During the rule of Iltutmish (1211-36), the Delhi Sultanate had to face three problems mainly. Firstly, how to subdue the rebelling powers.

But Raziya was the ultimate choice and became the real successor of Iltutmish. Raziya ascended the throne with the help of the army, a part of the nobles and the common people On the otherhand, the Turkish nobles thought that Raziya is in favour of non-Turkish nobles. So the nobles who were outside of Delhi, started opposing Raziya from the very inception of her rule. Besides, the Rajputs, too, opposed Raziya.

d. How did Alauddin Khalji combat the Mongol aggression ?
Answer:
During the rule of Alauddin Khalji (1296-1300 AD) Delhi was attacked twice by the Mongols (1299-1300 and 1302-03 AD). The Sultan built up a huge army to resist Mongol attack. A new city named Siri was set up to accomodate the soldiers. To make arrangements, for their provisions, he imposed taxes at a higher rate on the farmers of Doab.

After that he captured Hoysan and Kakahya one by one with the help of Malik Kafur, Alauddin captured Dwar samudro, and After that his army get victory over Tanjore. At last Alauddin finished his Military expeditions over South, with victory over Madurai and Pandya and his kingdom extended upto Indian ocean.

b. What was the relation between the Delhi Sultans and their nobles ?
Answer:
The Sultan who could show alround proficiency in the art of administration his rule would last long. From the time of Balban the powers and prestige of the Sultan began to increase. None was above the Sultan. If opposed, he must be punished. As a result they none could raise any question regarding the power and prestige of the Sultans and the nobles. In the time of Alauddin the nobles were harshly suppressed. But when the supervision of the Sultan loosened, the nobles increased their power.

Sultan had to maintain relation with the Ulemas too. As the priest advised the king so did the Ulemas about the Sultan. But the Ulema’s advice was not always obeyed by the Sultan. It also created strifes between the Ulemas and the Sultans. The Ulemas were punished sometimes by the Sultans. But to keep themselves in power intact the Sultans needed the support of the nobles and Ulemas. So the Sultan tried to please them with several tributes and honours to get their support.

c. What is Iqta? Why did the Sultans introduce the system ?
Answer:
The Sultans of Delhi extended the limits of their empires gradually. They felt it necessary to collect taxes from the newly acquired areas. It was also necessary to maintain peace in those areas too. The kingdoms which were conquered by the Sultans were supposed to be a province. These provinces were called Iqta. A military leader was in charge of these Iqtas.

He was called Iqtadar or Muqti or wate. These Iqtas were sab-divided in smaller and bigger ones. The ruler of the smaller Iqtas performed the military duties only, and the rulers of the bigger one performed his military duties along with administrative ones. To supervise the army, to remit the excess revenue to the Sultan and to maintain peace and order there, were some of the duties of the rulers of lerger Iqtas. The Iqtadars were fully under the control of the Sultan.

d. What is your opinion about the market regulations of Delhi in the reign of Alauddin Khalji?
Answer:
The administrative system of Alauddin Khalji was compleatly based upon military power. In the mean time he organised a huge army and fixed the salary of the soldiers. Alauddin fixed the price of daily necessities. During the time of Alauddin Khalji there were four big markets in Delhi.

Food, horses etc. were sold in these markets. To supervise the market price there were ‘Shahane-l-Mandi’ and ‘Dewan-I-Riasat. If the sellers used to take higher price than that of Alauddin fixed, or tried to cheat the buyer in weights they were severely punished.

e. Would you call the strife between Vijaynagar and the Sultani kingdoms a religious one? Give your arguments.
Answer:
Over three regions of Decan problems rose between Vijayanagar and Bahamoni sultanate. These were the regions in the coastal area of Tungabhadra, the basin area of Krishna- Godavari and Marathwara region. These areas were fertile and commercial too. Remember these areas not only created strifes between Vijaynagar and Bahmani kingdoms.

Previously the Chalukyas and the Cholas, Yadavas and Hoysalas too fought to occupy the same. The rulers of both the northern and southern borders of river Krishna took the title ‘Sultan’. They maintained many etiquettes of the Delhi sultans.

The Vijaynagar kings called themselves ‘Sultans’ among the Hindu kings. King Deva Roy II introduced the Turkish war tactics for his own army. During his reign, cultural contact was maintained between the north and south. So it can’t say that the strife between Vijaynagar and the Sultani Kingdoms a religious one.

Question 1.
What is Iqta system?
Answer:
In the Islamic empire of central Asia military aristocrats were awarded with Iqtas. The tenure of Iqtas was fixed. This system originated in the 9th century A.D. At that time sufficient revenue was not deposited in the royal exchequer. In 11th century’ A.D. the Iqta system could be found in the empire of the Seljuk Turks. During this time about half of the empire was distributed as Iqta.

Somewhere this system became hereditary. In the empire of the Ottoman Turks a similar system was introduced. It was called ‘Timar’. The Sultans of Delhi made several changes in the Iqtadari system for the expansion of the empire, collection of revenues and maintenance of peace and order. The Iqtdar or Mukti could have been the ruler of an entire province. He could have been a revenue collector also.

Question 2.
What is Jizya and Turuska Danda?
Answer:
The Muslim rulers used to collect Jizya from the non-muslims. In liew of this tax the people were provided safety, religious fight and security to property. In the 8th century A.D. the Arab commander Muhammad bin qasim first introduced this tax in Sind.

During the rule of the Delhi Sultanate, the Brahmins, women, minors and slaves were exempted from the Jizya. If the sages, blind, lame and mad men were poor then they w ere also exempted from the tax. Alauddin Khalji collected ‘Kharaj’ along with Jizya.

His objective was to decrease political and economic power of the influential non-muslims. Ghiyasuddin Tughlaq imposed the Jizya in such a manner that the non-muslims would neither be paupers nor challenge the state.

Firoz Shah Tughlaq went overboard to tax the brahmins also. Some Hindu kings introduced a tax similar to the Jizya. They used to impose the tax on the Muslims. The tax was called Turuska danda.

Long Questions and Answers:

Question 1.
Describe Delhi Sultanate during Lodi Rule.
Answer:
During the Lodi rule the power of the Sultan increased considerably. Sultan Bahlul Lodi followed the traditional custom of the Afghans and shared his power with the Afghan chieftains. But his objective was also to establish the dominance of the Lodi Afghans.

Conquering the neighbouring state of Jaunpur endorses this fact. However, his successor Sikandar Lodi did not believe in sharing his power with the Afghan chieftains. The Afghan chiefs were told that they were completely under the control of the Sultan. Their fortunes depended upon the will of the Sultan. Thus, he established his sovereignty over the Afghan chiefs and the common people.

Question 2.
Describe the administrative system of Delhi Sultanate.
Answer:
The real head of the administration of Delhi Sultanate was the Sultan himself. All powers of governance, the army, law and judiciary were in the hands of the Sultan. But a single individual could not look after all administrative responsibilities. So the Sultan appointed ministers and officials. His order was the final word.

In this way Sultanate administration developed with the Sultan at the centre. This is known as centralized administration. They distanced themselves from others, pronounced harsh judgements, and did not differentiate between the rich and the poor, common man and noble during trial. The Sultan who had the efficiency to look after all aspects of administration could rule for a long period. During the reign of Balban the power and prestige of the Sultan increased.

Nobody was above the Sultan. Any opposition would be penalized. So the nobility (Amirs) no longer questioned the power and prestige of the Sultan. During the reign of Alauddin, they were ruthlessly suppressed. But whenever the central administration weakened, the power of the nobility increased.
Besides the nobles, the Sultans had to keep connection with Ulema.

As the priest advised the king, the Ulema advised the Sultans. But most of the time their advice was not followed by the Sultans. Hence, the Sultan did whatever he thought to be the best. And so the Sultans often had conflict with the Ulema. But to keep their power intact the Sultan needed the support of the Ulema and the Omrah. Sometimes the Sultans even punished the Ulema.

Question 3.
Describe the control over market price by Alauddin Khilji.
Answer:
The administrative system of Alauddin Khilji was completely dependent on military power. He organized a huge army and fixed the salary of soldiers. He also fixed the prices of all daily commodities. During his reign, there were big markets in Delhi. Food, horses, cloth etc. were sold there.

The Shahna-i Mandi and the Diwan-i Riyasat looked after the markets. Severe punishment was given to offenders for demanding in excess of the fixed price or cheating the buyer in weight. Alauddin introduced a ration system. The people were provided grain and daily necessities by the Sultan when required.

Question 4.
What is Jizya and Turaska Danda?
Answer:
The Muslim rulers used to collect Jizya from the non-Muslims. This was an individual tax. In lieu of this tax the people were provided safety, religious right and security to property. In the 8th century A.D. Muhammad bin Qasim first introduced this tax in Sind.

During the rule of the Delhi Sultanate, the brahmins, women, minors and slaves were exempted from the Jizya. Alauddin Khilji collected ‘Kharaj’ long with jizya. His objective was to decrease the political and economic power of the influential non-Muslims. He thought that these people were creating discontent and. rebellion in the empire.

Ghiyasuddin Tughlaq proposed the Jizya in such a manner that the non-Muslim would neither be paupers nor challenge the state. Firoz Shah Tughlaq went overboard to tax the brahmins also. Some Hindu kings introduced a tax similar to the Jizya. The tax was called Turuskadanda. They used to impose this tax on the Muslims.

Question 5.
Who was the greatest ruler of madieval Bengal, and why?
Answer:
Alauddin Hussain Shah was the greatest ruler of medieval Bengal. His reign of 26 years (1493-1519) was famous for his liberal policy. The Hindus were appointed in important postions in his administration. The Wazir of Alauddin, his physician, bodyguard and the chief of the mint were Hindus. Sultan Hussain Shah was a gentle and amiable person. He was respectful of all religions.

It is said Sultan Hussain Shah was a devotee of Sri Chaitanya. One of the two famous brothers, Rup and Sanatan, was appointed as his Personal Secretary (Dabir-i Khas). Hussain Shah was regarded as the incarnation of Lord Krishna. He was extremely enthusiastic in the research and practice of the Bengali language. Bengali literature flourished during his reign.

Question 6.
Mention Vijaynagar in the accounts of foreign travellers.
Answer:
Many foreign travellers visited Vrjaynagar. The most notable of them were Nicolo Conti of Italy, Persian envoy Abdur Razzak, Potuguese travellers Paes and Nuniz, Duarte Barbosa etc. All of them were astonished to see the treasures of Vijaynagar.

The city of Vijaynagar was surrounded by seven walls. Agriculture was the chief occupation. Irrigation system was well organized. Land revenue was the main source of income. Apart from agriculture, trade, commerce and industry flourished. Vijaynagar had close trade relationship with the Portuguese. But the travellers had also remarked that the life style of the rich and poor was markedly different.

Question 7.
Give a picture of Vijaynagar in the eye of Portuguese traveller Paes.
Answer:
“….The city is as big as Rome and very beautiful to look at. There are many orchards – both in the city gardens and in the gardens of the mansions. A number of canals of clear flow through the city. There are large tarks. A palm grove and fruit trees are found close to the royal palace.

The population of this city is high. So many people and elephants stroll through the roads and lanes that it is difficult for the soldiers and cavalry to pass through. No other city in the world provides such food as in Vijaynagar. Rice, wheat and other crops are available in large quantity. The’ numbers of oxen carrying loads in markets and on roads makes it impossible to walk through. Either one has to wait for long or take a different route.”

A growth in mercantile activities was noted in South India between the 9th and centuries. Various inscriptions inform us about the trade bodies like co-operative socities and the commodities of trade which were catered by the traders. The trade Guilds awarded land to the temples.

The copper plate inscriptions from South India record this. Due to the growing over mercantile activities of the Cholas in South east Asia, India’s influence on the trade and comment in this region gradually increased.

All the above mentioned crops are still cultivated.

In the Sena era, poet Joydev was the famous poet in the court of Lakshmana Sena. The theme of his famous poetry Geet Govindam was the story of romantic love of Radha and Krishna. Another poet Dhoyee, on the court of Lakshman Sena, wrote the Pabanduta Poetry.

Three more poets of this era was Gobardhan, Umapati Dhar and Sharan. these five poets were ‘five gems’ of the court of Lakshman Sena. The book, Sadukti Karnamrits was a compilation of poems of several books.

d. Why did the Sena rule last lesser a period them that of the Pala rule?
Answer:
The Sena rule did not witness much publicity and popularity as it was in the Pala period. They attached much importance to the Brahmin religion. The Pala rule could strike their roots during their rule of400 years. But the Senas could not do so in their hundred years rule.

When Gopal became the king, he was backed by the support of the people. But Vijay Sena, the founder Of the Sena dynesty had no popular suport behind him. Pala rulers could make themselves acceptable to the people. The Senas failed to do it. In the field of learning, religion and the artistic activities, the Pala era was far above the Senas.

4. Write in details (100 to 120 words):

a. If you want to draw a picture of the feudal system, why does it look like a triangle? How did the feudal lords spend their livlihood in this system?
Answer :
The triangle is wide at the base. This means, the people at the bottom are more in number. Above them are feudal or middle level leaders. Above them are a few principal leaders. The king is above the rest. The division of authority and revenue in this manner forms a system known as feudalism.

The feudal groups had a common characteristic. They did not work to earn their living. They lived on other people’s income. There were divisions in these groups. Some headed a village. Some others controlled a group of villages. Yet some others controlled a whole region. In this manner, the society was divided into different classes, comprising the king, the group leaders and the people at large.

The principal feudal lords and the other lords always faught among themselves. Each tried to expand his authority. Often they joined hands to wage a war against the king. Apart from collecting revenues, they controlled the civil and legal administration of the annexed villages. Often they also revolted against the king. The weakness of the king’s authority becomes evident from this. Because of these feudal lords, the self-government of the villages was destroyed.

b. Compare and contrast the agricultural and commercial progress of the Pala-Sena period.
Answer:
The basic resources of the economic condition of Bengal in the Pala-Sena period were agriculture, industry and trade. The importance of trade started reducing during this age. The mercantile activities of the Arab traders along the Arabian Sea coast in Western India led the Bengal traders to step back.

Due to the decay in foreign trade, the economy of Bengal became dependent on agriculture. The fall of trade was related to the devaluation of currency. The use of gold and silver coins started waring during the rule of the Palas and Senas in Bengal.

‘Cowrie’ become the main medium of trade. In this agarian Society, there are many instance of land grant. The kings granted land to religious institutions. The kings collected one-sixth of the produce from the farmers as revenue. Cotton was the principal commodity of trade. The fine cotton clothes of Bengal became famous all over the world. Handicrafts included wooden and metalic utensils and ornaments were useful.

c. Write a note about the art and architecture of Bengal in the Pala period.
Answer:
The art form of the Pala era is called Eastern Indian style of art. The Gupta art was the Predecessors of the Pala style. Of the Pala architecture the stupas, the Bihars and the temples deserve special mention. Due to human anger and the curse of nature the sculptures were totally destroyed.

The stupas built in the reign of the Pala kings looked like the mountain peaks. In West-Bengal and Bangladesh these stupas were found in numbers. But the original thinking was lacking in the construction of the stupas. These Bihars were the abodes of the Buddhists and the centres of Buddhist learning. Sompuri Bihar of Paharpur was the famous one of the Pala stupas.

The temple in the middle of Sompur Bihar was really remarkable among temples. These temples were square in size. There were underground compartments, a path going around the temple. Mamiupa’. were very high pillars. In construction of the temples, local burnt bricks and mud were used.

The famous specimens of the Pala arts were its sculptures. The Paharpur field of excavation was the best of them, where a large number of specimens are available. These were the examples of folk art. Happiness and miseries of daily lives, social life and religions belief have been depicted. The pictures drawn before the eleventh and twelfth centuries are not available at present.

The pictures which have been found now’ were only used as illustrations of the Buddhist manuscripts. In the Pala era, Bitpal and his son Dhiman were famous artists during the eighth and ninth centuries. They showed their skill in the metallic art, sculpture and painting.

d. Write a note about the society and religion of the Pala-Sena era,
Answer:
The life of the general people in the society was mostly afluent. But the economic condition of the people without land property and the labourers was not at all good. The literature of that time proves the same. The Sena rule did not witness much publicity and popularity as it was in the Pala period. They attached much importance to the Brahmin religion. Though the Buddhism existed, the Buddhists were not benifitted much by the government as it was before. The Brahmins only were the sole benificiaires as the head of the society.

There were several sub-divisions among the Brahmins. Brahmins were treated as a mixed caste of the sudras. The Brahmins could perform the duties of the ton-Brahmins, but the non Brahmins could not perform duties of the Brahmins. Beside the tribal people were there in the same period. Pala rulers could make themselves acceptable to the people. The Senas failed to do it.

Answer:
In the A.D. 8th century the Pala emperor Dharntapala founded the Vikramshil university or mahavihara near Bhagalpur in the northern part of Magadha. This university lasted for the next 500 years. Over 100 teachers were involved in the teaching and study of religion.

Students used to come there to study. Grammar, logic, philosophy were taught here. Maximum three thousand students could avail free education. Students had to appear for an admission test before enrolment. At the end of their course they were awarded with titles.

Vikramshila was the main centre for Vajrayana cult: Many valuable manuscripts were preserved in its library. Dipankar Srijnan (Atish. was one of the mahacharyas of this university. This university was also ransacked by the Turkish invaders in the 13th century.

Question 11.
Describe the main architectural monuments of the Pala age.
Answer:
The main architectural monuments of the Pala age were stupa, vihara and temple. Now most of them do not exist. In ancient India there was a custom of building Buddhist and Jain stupas. In fact, the Buddhists in particular, constructed many stupas. Initially these stupas were round shaped. But later, they were conical in shape.

The stupas built during the Pala Age looked like shikhams or mountain peaks. No originality is seen in the design of the stupas of Bengal. The viharas were the residences of the Buddhist monks and also seats of learning of Buddhist knowledge systems.

Sompuri vihara at Paharpur was a prominent vihara in the Pala reign. The temple of Sompuri vihara is also worth mentioning. The temple was square shaped. The temple had underground chambers or garvagriha, a path for going around the temple, an altar and lofty pillars. The temple was built with burnt brick and clay.

Question 12.
Write a short note on feudal system of India.
Answer:
The growing importance of the regional monarchs had an impact on contemporary Indian society and economy. A section of the society gained enormous power. The contemporary writers had addressed this group as ‘Samanta’, ‘Raja’, ‘Raimak’ etc. Some of them were high officials in the princely courts. Sometimes they were granted lands in lieu of salary.

The revenue from such lands was the income of this group. In some regions, the defeated kings also enjoyed the revenue of those areas. Often the tribal leaders who were skilled in warfare controlled certain regions.

These groups had one common feature. None of them gave labour for production. They lived on the revenue or output of others’ labour. Again, there were divisions in these groups. Some headed a village. Some controlled a group of villages. Others controlled an entire region. In this manner the society was stratified into different classes comprising the king, the group leaders and the common people.

The Samantas Mahasamantas (feudal lords. had constant conflict with each other. Sceryone wanted to increase his influence. Sometimes they even unified to fight against the king. Besides extracting revenues, these groups used to govern the village and even give judgment. Often they refused to recognize the authority of the king. The weakness of the sovereign becomes evident.

Additional Questions and answers

Question 1.
Give a short note on Pala Dynasty.
Answer:
The first hundred years of Pala rule was the period of extending their domination. In the later 130 years their influence gradually declined. The founder of the Pala dynasty, Gopala, included almost all of Bengal within his kingdom.

His successor, Dharamapala, took part in the ‘Tripartite Struggle’ for control of northern India. His son, Devapala expanded the frontiers of his empire quite like the other kings of north and south India. During his reign, the empire extended from the foothills of the Himalayas in the north to the Vindhyas in the south and from Kamboja in the north-west to Pragjyotishpur in the east.

The domination of the Palas started to wane after the reign of Devapala. The reason was inner conflict of the Pala rulers. Moreover, in the 9th century the Rashtrakutas of the Deccan, the Pratiharas of the western region and the rulers of Odisha conquered many parts of Bengal and Bihar.

As a result, the existence of the Palas in Bengal was at stake. Their kingdom was restricted to the limits of Magadha. However, during the time of King Mahipala I there had been an attempt to revive the former glory of the Pala reign.

Ramapala became king towards the end of the 11th century. The entire Varendra region went beyond the control of the Palas as a result of the Kaivarta revolt. Ramapala succeeded in recovering it. He was able to restore the domination of the Palas to some extent. However, the Pala dynasty came to end within fifty years after the death of Ramapala.

Question 2.
Write a short note on Kaivarta revolt.
Answer:
During the reign of the Palas the Kaivarta revolt took place. The Kaivartas were probably boatmen or fishermen. In that period the Kaivartas had influence in North Bengal. The account of the revolt can be found in the Ramcharita of Sandhyak ar Nandi. Three leaders of that revolt were Divya (Divvok), Rudok and Bhim. Divya was an official of the Pala empire during the reign of Mahipala II.

Taking advantage of the weakness of the Pala kings, he revolted. Mahipala was killed while suppressing the revolt. Divya captured Varendra and became its ruler. Not much is known about the magnitude of the revolt or the number of people supporting the revolt. Ramapala. the younger brother of Mahipala tried to defeat Divya and recover Varendra but he failed.

The Kaivarta king Bhima was also a popular ruler. At this time the authority of the Palas was limited to North Bihar and North-West of Bengal. Ramapala later defeated and killed Bhima with the help various chieftains (Samanta) of Bengal and Bihar. After that he established Pala rule in Varendra. Kamarupa of Bengal and part of Odisha. This revolt had exposed the weakness of central authority in the later part of Pala rule.

Question 3.
Write about the Sena dynasty.
Answer:
The kings of the Sena dynasty started to rule in Bengal in the 11th century. Their dynasty came to an end towards the beginning of the 13th century. The rulers of the Sena dynasty were originally from the Karnata region of South India. Originally they were Brahmins, but later became Kshatriyas.

Samantasena of the Sena lineage had left Karnata for Radh some time ago. During the rule of Samantasena and his son Hemantasena. the Senas had developed some domination over the Radh region. Vijaysena, the son of Hemantasena. expanded the territory of the Sena dynasty by occupying Radh, Gauda, eastern Bengal and Mithila.

Ballalsena, the next ruler defeated the Pala king Gobindapala. Thus Ballalsena struck the final blow on the Palas. He reformed the society and established orthodox Brahmanical rites and practices. His son and successor Lakshmanasena established his domination over Prayag. Benaras and Puri. His capital was Bikrampur in castern Bengal. Another important town of that period was Lakshmanavati (Gauda). In A.D. 1204/5 the Sena dynasty came to an end with the invasion of the Turks.

Question 4.
Write about the Cholas of South India.
Answer:
The Cholas set up their kingdom on the deltaic region of Kaveri and its tributaries. Vijayalaya overthrew King Muttabaiya, the ruler of the area. and founded the Chola dynasty, A new town called Thanjavur or Tanjore was set up as the capital of the Cholas’. The successors of Vijayalaya expanded their kingdom further. The Pandya region of the south and the Pallava region of the north came under their control. In A.D. 985 Rajaraja I was able to establish the Chola supremacy in present Kerala.

Tamil Nadu and in the vast areas of Karnataka. His son Rajendra. defeated the Chalukya power of Kalyani. He adopted the title Gangaikondachola after defeating the Pala king on the banks of the river Ganges in an expedition against the Pala dynasty. Both Rajaraja I and Rajendra I set up efficient navies. As a result, the Cholas were able to maintain control over commerce between India and the South East Asian countries.

Answer:
The rock cycle is the process by which rocks of one kind change into rocks of another kind. There are three main kinds of rocks: igneous rock, metamorphic rock and sedinientary rock. Each of these rocks can change in to the other kinds by physical process : cooling. melting, heating, weathering. compacting, cementing and pressure.

Question 6.
State the characteristics lies of different soils.
Answer:
Sandy soil : i) The grains of this soil are large. 2) It can not hold more water. 3) Air can passes through this soil. 4) It is not fertile. 5) It is not fit for agriculture.
Clayey soil : i) The grains of the soil is very fine. ii) The capasity of holding air is more. iii) Air can not pass through this soil easily. iv) It can not be broken easily if it becomes dry. v) Dust clayey soil is like powder.
Loamy soil : i) It is fit for agriculter. ii) The grains of the soil is medium. iii) The ability of holding water is medium. iv) The ablity of passing air is medium.

Question 7.
Classify the igneous rock according to their origin.
Answer:
According to their origin ignious rocks are of two types-i) Intrusive rock, ii) Extrusive rock. Intrusive rock is further divided into two types : a) Plutonie rock, b) hypabyssal rock.

When the hot molten lava of earth chamber can not reach on the earth’s surface it cools down in the earth’s chamber for many years and solidifies. This is called intrusive rock.

In the earth chamber when the magma cools down and solidifies to form a rock it is called plutonic rock. On the other hand when the magma cools down and solidifies in the crack before reaching the earth surface, this is called hypobyssal rock. Granite is the example of hypobyssal.

When the magma comes out through the crater of the volcano at the time of volcanic erruption, it cools down and solidify in contact of coal air then it is called extrusive rock. Basalt is the example of extrusive rock.

Question 8.

Answer:
a) Fossils can not be found in igneous rock. Fossils are found in sedimentary rocks.
b) Igneous is the rock of primery stage. Sedimentary rock is the rock of second stage.
c) Igneous rock is formed either on earth’s surface or in the earth’ chamber and sedimentary rock is formed under the ocean.
d) Ignious rock is crystalized but sedimentary rock is not crystalized.
e) There is no layer in igneous rock but layers are found in sedimentary rocks.
f) lgneous rock is hard but sedimentary rock is less hard

Question 9.
Why is fossil found in sedimentary rocks?
Answer:
Fossil is found in sedimentary rocks because sedimentary rock is formed under the sea or lake by accumulating sediment layer by layer. then the dead body of marine plants or animals are burried at the time of accumulating sediment and solidifies to form rock. After that the mark of their bodies are left in rock layers. So the fossils are found in sedimentary rocks. As the formation of the sedimentary rocks is a long process, in the long past the fossils of the animals that appeared in different ages can be found in the sedimentary rocks and it helps us to gain knowledge about the ancient plants and animals or the climate of that ages.

Additional Questions and answers :

Question 1.
Mention the factors of formation of soil.
Answer:
Rocks: The characteristics of a soil depend on the nature of rock(s) from which it is derived. However, soil formation is also influenced by several other factors.

Climate : Climate plays a very significant role in the formation of soil. Soil forms faster in warm and rainy climates and takes a lot of time to form in cool and dry climates. So, deeper soils are generally found in warm and humid regions.

Relief: the relief of the land influences the processes of formation of soil. Soil is unlikely to form on steep slopes. Gentler slopes support better and gradual development of soil.

Organic matter : plants and animals, alive or dead, form a very small part of soil, but are very significant. Ants, moles, earthworms and snakes loosen the soil and let air and water enter in to it. Dead remains of organisms supply nutrients to a soil.

Time : Soil does not form in a day. The natural process of soil formation may span through thousands, and sometimes, even millions of year.

Answer:
In the mountain region if the rever valley is very narrow and deep like ‘I’ or ‘V’ shaped, then it is called george. When the George is in dry ares it is called Canyon.

Question 5.
How is waterfall formed?
Answer:
In the upper course of the river if hard and soft -rocks are arranged in alternate layers. the softer layers get eroded faster and step-like features are formed. Now the the water now plunges down these steep-sided and form waterfalls.

Question 6.
What is Estuary?
Answer:
At the meeting point of the river and sea the river valley becomes wide. At the time of high tide the saline water of see enters the river through its mouth and form estuary by widen the mouth. Muddy water is found is the mouth of the river and the river vaitey becomes wide.

Question 7.
What is flood plain? Give examples.
Answer:
In the lower course of a river the flood waters leave sediments in the extensive plain lands on both banks of the river, thereby form flood plain. The lower course of the \mathrm{Hv How has flood plains.

Question 8.
What is perennial river?
Answer:
The streams with their sources high up in the mountains are generally fed by ice-melt water. The channels do not dry up during any time of the year. Such type of river is called perennial river.

Question 9.
What is non-perennial river?
Answer:
There are some rivers which are filled with water during rainy season. During other parts of the year their channels tend to dry up. They are called non-perennial rivers.

Long Questions & Answers : (3 marks for each question)

Question 1.
Why is ‘V’ shaped valley formed in the upper course of the river?
Answer:
In t e upper course of the river the velocity of the water is high and so the water break the pelbbles and boulders into small pieces and are transported by the water. These pebbles and boulders struck the river bed. So lower cut is more than the side cut. Therefore the V shaped valley is formed in the upper course of the river.

Question 2.
Why is the delta not found in all river.
Answer:
The deposition is much in the lower course of the river. The eroded silt, mud, pebbles. sands brought by the river accumulate at the mouth of the river to form delta. Sometimes in many rivers the lower course could not be found or the amount of the load may be less. Besides if the water current is more the delta could not be formed.

Question 3.
What are the different functions of the river?
Answer:
The function of the rivers are of three types-i) Erotion, ii) Transportation and iii) deposition.

1. Erosion : The river struck the side rocks by the water current in upper course.
2. Transportation : The eroded rock particles are transported by the river water.
3. Deposition : The eroded rock particles are accumulated at the river bed and the mouth of the river in the lower course. This is called deposition.

Question 4.
Compare the function of the river in different courses.
Answer:

Question 5.
What are the different landforms created in the upper course of the river?
Answer:
The different landfroms created in the upper course :
i) Narrow ‘V’ shsped Valley : In upper course the lower cut of the river is more than side cut. Thus the ‘V’ shaped valley formed. This type of valley when becomes more deep it is called George. But in the desert area with limestone the upper cut is only occured, thus the river valley is ‘I’ shaped here. This is called Cannyon.

ii) Water fall : In the upper course of the river if the hard and soft rock bed lie horizontally, the soft rock erodes faster then hard rock and the hard rock forms step like structure and river water falls from higher to laower slope which is known as waterfalls. Sometimes water falls occurs in the upper course due to fault.

iii) Pot hole : when the boulders or rocks are carried by the river water they may strike the river bed and create holes. These are called poese holes.

Question 6.
What are the different land forms created in lower course.
Answer:
Old age of the river found after the middle course. This is called lower course. This is called main river valley. The main function of the river in lower course is deposition. The landform created by deposition are-i) delta, ii) flod plain.

i) Delta : When the river falls in the sea or lake it stops flowing and can not go any more in the sea. Thus the silt accumulae in the sea bed. The sedimentation is more in saline water. Years after years the accumulation of silt forms delta at the mouth of the river. The landform is triangular shaped or greek ‘Δ’ shape. The silt accumulaes at the river bed day by day and the delta increases towards the sea and the sea goes away from the land. For this reason the mouth of the river graduaily expands.

ii) Flood plain : The accumulation of sediments on the river bed makes it shallow. So the river overflows its banks during the rainy season. The flood waters leave behind cediments in the existensive plain lands on both banks of the river and form flood plains.

Question 7.
What are the different process of erosion?
Answer:
The different process of erosion are-i) abration, ii) attrition, iii) Corrosion, iv) Hydrolic action.

1. Abrasion : The rocks, pebbles. brought by the river, erode the river bed. This type of erosion is called abrasion which creats potholes in the river bed.
2. Attrition : The pieces of rocks. brought by the river, gradually become smaller by striking each other at last turn into sand. This is called attrition. For this the pebbles become round shaped.
3. Corrosion or solution : In the course of the river sometimes minerals present in the rocks in some places. Which desolve in the water and becomes eroded. This is erorsion by solution. This type of erosion is found in limestone area.
4. Hydrodlic action : When the river water flows violently, it strikes the two sides of the river valley. For this reason the comperatively soft rocks gradually erode. This type of erosion makes the river valley.

Question 8.
What are the different landforms created in the middle course of the river due to the deposition.
Answer:
The slope of the river decreases in the middle course of the river. Eroded materials are accumulated at the both side of the river bank and in the river bed.

i) Meander : In the middle course the velocity of the river water decreases and the river flows slowly. In this situation the river meanders when it gets obstructed. This is called meander. Meanders are found it the river Ganga near Baranasi.

ii) Sand bars, River Islands : In the middle course of a river its capacity to carry eroded materials is also reduced. Its starts depositing the transported pebbles, sand and silt on its bed and along the banks. This deposits may choke the channel and form sand bars, or sometimes, river islands.

iii) Ox-bow lake : The more a river meanders, or the more volume of water flows through it, the loop of the meander can get seperated from the main channel by reverine deposits. This seperated part generally has the shape of a horse-shoe and is called an ox-bow lake.

Long Questions & Answers : (3 marks for each question)

Question 1.
How are fold mountains created? Give an example.
Answer:
Fold mountains are created when two plates move together. This can be where two continental plates move towards each other or a continental and an oceanic plate. The movement of the two plates forces sedimentary rocks upwards into a series of folds.

Example: At the place of the Himalaya Mountain there was a geosyncline almost 10 crore years ago. The name of the land to its north was Angara land and to the south was gondowana land. For many years the silt, brought by the rivers of these two land was accumulated at the bed of Tethes. Due to the downward pressure of the layers of the silt the bed of Tethis went downword and the two land came closer. For this reasen the fold occured on the silt and it uplifted to form a mountain. As the fold mountain is originated from geosyncline the bredth of the mountain is lesser than the length of the mountain.

Question 2.
What is valcanic Mountain?
Answer:
Hot molten magma remains in the earth chamber. For earth’s movement or only other causes the hot molten magma expands. At that time due to changing of earth’s movement the magma comes out through any openings of the earth’s surface and deposits around the cracks to form volcanic mountain. Due to the course of time it becomes conical in shape. This is called valcanoic mountain.

The example of the volcanic mountains are Etna in Sicily, Visuvius in Italy, Kilimanjaro in Africa, Fujiyama in Japan etc. But the Guaiyati in Chilly is he highest(19.082 \mathrm{Ft})$ active volcanic mountain of the world.

Question 3.
Classify the volcanie mountain according to their shape and structure.
Answer:
According to the shape and structure the volcanic mountains are classified into four categories-i) Volcanic mountain with conical shape, ii) Volcanic mountain with dome shape, iii) Valeanic mountain with explossive crater, iv) Volcanic Mountain with composite conical.
i) Volcanic mountain with conical shape : This is formed by large explosion. It looks like cone, This type of volcano is found in Japan.
ii) Volcanic mountain with dome shape : Due to large explosion the thick magma comes out form dome shaped Volcano. This types of volcano is found in Hawai island.
iii) Volcanie mountain with explossive crater : This type of volcano is formed due to large explosion by making big crater. This type of volcanic mountain is found in lceland.
iv) Composit volcanic mountain with conical shape : When explosion countinues for long time a main erativ forms with other earths surrounded it. This type of Valcano is found in Maxico.

Question 4.
Classify Plateaus according to their origin.
Answer:
According to their origin plateaus are classified into three categories-i) Dissected plateau, ii) Intermontane plateau, iii) Lava plateau
i. Causes for the origin of dissected plateau : Sometimes the old fold mountain is eroded by the natural forces for long time to form high plateau: When the soft rocks of the high mountain eroded or brought away by the wind or river water leaving the hard rocks only as the peak of the mountain then it is called Residual plateau. The Residual plateau is sometimes dissected by narow river vally, it is called dissected plateau. The example of dissected plateaus are Bindhya plateau in India, Highland of Scottland etc.

ii. Cause for the origin of Intermontane plateaus: At the time of the formation of fold mountain the places comperatively lower uplifted to form plateaus for the earthquake. This type of plateaus are generally surrounded by the mountains. This is called inter mountaine plateau. The example of intermontane plateaus are the Tibetan plateau, Iranian plateau etc.

iii. Cause for the origin of volcanic plateaus: The lava plateau is made up with bassalt rock. The hot molten lava comes out through the openings of the earth surface and begines to accumulate to the earths surface. In due course of the time the lava cools down and hardens to form plateau. This types of plateau froms due to the accumulation of lava. Thus it is called lava plateau or volcanic plateau or depositional plateau. The example of this type of plateau in the Decan plateau in India, the Somalian and Etheopian plateau, the Puner plateau in Argentina.

Question 5.
Classify the plain according to their origin.
Answer:
According the their origin plains are classified mainly into two categories-

1. Plain of accumulation
2. Plain created by earths movement.

1. The classification of plain of accumulation : The plain of accumulation is also devided into 8 categories-

1. alluvial plain
2. flood plain
3. deltaic plain
4. coastal plain
5. lake plain
6. Lava plain
7. Glacier plain
8. loess plain

2. Plain created by earth movement : This type of plain is classified into two categories

1. uplifted and
2. downward plain.

Question 6.
Write the causes for the formation of different plains.
Answer:
i) The silt accumulated under the rivers, seas and lakes to form alluvial plain (genstic plain), ii) For the volcanic erruption of the volcano (lava plain-northen part of the Decan), iii) the plain formed by the glacier (Prairries in North America), iv) In desert region the sand blown by the wind and deposited to form plain (Loess plain in china), v) The low hills and plateau eroded to form plain (some part of the Ranchi plateau), vi) For earthquake high land goes downward to form plain (Taranian plain) or uplifted to form plain (Karamandal coast in India).
