Q1 What are Tectonic Plates? (NCERT QUESTION)

Ans 1. The crust (upper part) of the earth has been formed out of seven major and some minor plates. These are called tectonic plates. 

  1. A Tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. 
  2. Plate size can vary greatly, from a few hundred to thousands of kilometers across; the Pacific and Antarctic Plates are among the largest. Plate thickness also varies greatly, ranging from less than 15 km for young oceanic lithosphere to about 200 km or more for ancient continental lithosphere.

 

Q2 Distinguish Between the Western Ghats and the Eastern Ghats. (NCERT QUESTION) 

Ans 

Western Ghats
Eastern Ghats
1. The Western Ghats are higher than the Eastern Ghats.
The Eastern Ghats stretch from the Mahanadi Valley to the Nigiris in the south. 
2. Their average elevation is 900– 1600 metres as against 600 metres of the Eastern Ghats. The height of the Western Ghats progressively increases from north to south.
The Eastern Ghats are discontinuous and irregular and dissected by rivers draining into the Bay of Bengal.
The Western Ghats cause orographic rain by facing the rain bearing moist winds to rise along the western slopes of the Ghats. The Western Ghats are known by different local names. The highest peaks include the Anai Mudi (2,695 metres) and the Doda Betta (2,637 metres).
3. Mahendragiri (1,501 metres) is the highest peak in the Eastern Ghats. Shevroy Hills and the Javadi Hills are located to the southeast of the Eastern Ghats.

 

Q3 Describe how the Himalayas were formed. 

Ans 1. The Himalayas and the Northern Plains are the most recent landforms. From the viewpoint of geology, Himalayan Mountains form an unstable zone. 

  1. The whole mountain system of Himalaya represents a very youthful topography with high peaks, deep valleys and fast flowing rivers. 
  2. The northern plains are formed of alluvial deposits. The peninsular plateau is composed of igneous and metamorphic rocks with gently rising hills and wide valleys.

 

Q4 Which are the major physiographic divisions of India? Contrast the relief of the Himalayan region with that of the Peninsular plateau. (NCERT QUESTION)

Ans The physical features of India can be grouped under the following physiographic divisions:

  1. The Himalayan Mountains 
  2. The Northern Plains 
  3. The Peninsular Plateau 
  4. The Indian Desert 
  5. The Coastal Plains 
  6. The Islands 

The Himalaya consists of three parallel ranges in its longitudinal extent. A number of valleys lie between these ranges. The northernmost range is known as the Great or Inner Himalayas or the ‘Himadri’. It is the most continuous range consisting of the loftiest peaks with an average height of 6,000 metres. It contains all the prominent Himalayan peaks. 

The Deccan Plateau is a triangular landmass that lies to the south of the river Narmada. The Satpura range flanks its broad base in the north while the Mahadev, the Kaimur hills and the Maikal range from its eastern extensions. Locate these hills and ranges in the physical map of India. The Deccan Plateau is higher in the west and slopes gently eastwards. An extension of the Plateau is also visible in the northeast– locally known as the Meghalaya and Karbi-Anglong Plateau. It is separated by a fault from the Chotanagpur Plateau. Three Prominent hill ranges from the west to east are the Garo, the Khasi and the Jaintia Hills.

 

Q5 What are the three types of plate movements on the earth? 

Ans The three types of plate movements are the following. 

  1. Convergent Boundary: When the plates come towards each other, they form convergent boundaries. The plates collide, crumble or even slide under the other. It may also be known as folding movements. For example, Himalayan mountains were formed by convergence of the Indo-Australian plate against Eurasian plate. 
  2. Divergent Boundary: These are formed when the plates move away from each other, they form divergent boundaries. They are also called faulting movements. For example, the North American Plate diverges from the Eurasian Plate. 
  3. Transform Boundary: When some plates move past each other form transform boundary, e.g. San Andreas fault. The western half of California is moving north because it is part of the Pacific Plate and Eastern half of California is moving south because it is part of North America.

Q2 Read the extract given below and answer the questions that follow:

The Northern Plain is broadly divided into three sections. The Western part of the Northern Plain is referred to as the Punjab Plains. Formed by the Indus and its tributaries, the larger part of this plain lies in Pakistan. The Indus and its tributaries – the Jhelum, the Chenab, the Ravi, the Beas and the Satluj originate in the Himalaya. This section of the plain is dominated by the doabs. Doab’ is made up of two words – ‘do’ meaning two and ‘ab’ meaning water. Similarly ‘Punjab’ is also made up of two words -‘Punj’ meaning five and ‘ab’ meaning water. The Ganga plain extends between Ghaggar and Teesta rivers. It is spread over the states of North India, Haryana, Delhi, Uttar Pradesh, Bihar, partly Jharkhand and West Bengal to its East, particularly in Assam lies the Brahmaputra plain. The Northern plains are generally described as flat land with no variations in its relief. It is not true. Their vast plains also have diverse relief features. According to the variations in relief features, the Northern plains can be divided into four regions. The rivers, after descending from the mountains, deposit pebbles in a narrow belt of about 8 to 16 km in width lying parallel to the slopes of the Shiwaliks. It is known as bhabar. All the streams disappear in this bhabar belt. South of this belt, the streams and rivers re-emerge and create a wet, swampy and marshy region known as Terai. This was a thickly forested region full of wildlife. The forests have been cleared to create agricultural land and to settle migrants from Pakistan after partition.

Q1 Give an account of the Northern Plains of India. (NCERT QUESTION)

Ans 1. The northern plain has been formed by the interplay of the three major river systems, namely– the Indus, the Ganga and the Brahmaputra along with their tributaries. This plain is formed of alluvial soil. 

  1. The deposition of alluvium in a vast basin lying at the foothills of the Himalaya over millions of years, formed this fertile plain. It spreads over an area of 7 lakh sq. km. The plain being about 2400 Km long and 240 to 320 Km broad is a densely populated physiographic division. 
  2. With a rich soil cover combined with adequate water supply and favourable climate, it is agriculturally a very productive part of India. 
  3. The rivers in their lower course split into numerous channels due to the deposition of silt. These channels are known as distributaries. 
  4. The Northern Plain is broadly divided into three sections. The Western part of the Northern Plain is referred to as the Punjab Plains. Formed by the Indus and its tributaries, the larger part of this plain lies in Pakistan. The Indus and its tributaries–the Jhelum, the Chenab, the Ravi, the Beas and the Satluj originate in the Himalaya. This section of the plain is dominated by the doabs.

 

Q2 Write short notes on the following: (NCERT QUESTION)

  1. The Indian Desert
  2. The Central Highlands 
  3. The Island Groups of India 

Ans 1. The Indian Desert The Indian desert lies towards the western margins of the Aravali Hills. It is an undulating sandy plain covered with sand dunes. This region receives very low rainfall below 150 mm per year. It has an arid climate with low vegetation cover. Streams appear during the rainy season. Soon after they disappear into the sand as they do not have enough water to reach the sea. Luni is the only large river in this region. Barchans (crescent-shaped dunes) cover larger areas but longitudinal dunes become more prominent near the Indo-Pakistan boundary.

  1. The Central Highlands The Peninsular plateau consists of two broad divisions, namely, the Central Highlands and the Deccan Plateau. The part of the Peninsular plateau lying to the north of the Narmada river covering a major area of the Malwa plateau is known as the Central Highlands. The Vindhyan range is bounded by the Central Highlands on the south and the Aravallis on the northwest. The further westward extension gradually merges with the sandy and rocky desert of Rajasthan. The flow of the rivers draining this region, namely the Chambal, the Sind, the Betwa and Ken is from southwest to northeast, thus indicating the slope. The Central Highlands are wider in the west but narrower in the east. The eastward extensions of this plateau are locally known as the Bundelkhand and Baghelkhand. The Chotanagpur plateau marks the further eastward extension, drained by the Damodar river. 
  2. The Island Groups of India This group of islands is composed of small coral islands. Earlier they were known as Laccadive, Minicoy and Amindive. In 1973 these were named as Lakshadweep. It covers a small area of 32 sq km. Kavaratti island is the administrative headquarters of Lakshadweep. This island group has a great diversity of flora and fauna. The Pitli Island, which is uninhabited, has a bird sanctuary. An elongated chain of islands located in the Bay of Bengal extending from north to south. These are Andaman and Nicobar islands. They are bigger in size and are more numerous and scattered. The entire group of islands is divided into two broad categories – The Andaman in the north and the Nicobar in the south. It is believed that these islands are an elevated portion of submarine mountains. These island groups are of great strategic importance for the country. There is great diversity of flora and fauna in this group of islands too. These islands lie close to the equator and experience equatorial climate and have thick forest cover.

 

Q3 Describe the three parallel ranges of the Himalayas. 

Ans The three parallel ranges of the Himalayas are: 

  1. Himadri (Greater or Inner Himalayas): It is the most continuous range of the Himalayas. It has loftiest peaks with an average height of 6000 metres. For example, Mount Everest 8848 metres, Kanchenjunga 8598 metres. The folds of this part are asymmetrical in nature. It is perennially snowbound and gives rise to a number of perennial rivers e.g. Ganga rises from Gangotri glacier. 
  2. Himachal (Lesser Himalayas): These ranges lie south of Himadri and form the most rugged ranges. These ranges are mainly composed of highly compressed and altered rocks. The average height of the lesser Himalayas is between 3700 and 4500 metres. The important ranges are the Pir Panjal, the Dhaula Dhar and the Mahabharata. This range consists of the famous valley of Kashmir, the Kangra and the Kullu Valley. This range is also famous for its hill stations like Mussoorie, Nainital, Ranikhet, Shimla. This range is also famous for its fruit orchards. 
  3. Shiwaliks (Outer Himalayas): These ranges extend over a width of 10-50 km and height between 900 and 1100 metres. These ranges are made up of unconsolidated mud and rocks brought down by the Himalayan rivers. These ranges are more prone to landslides and earthquakes. They are more prominent in the western part of India. The longitudinal valleys lying between lesser Himalayas and the Shiwaliks are called ‘Duns’ like Dehra dun, Kotli Dun and Path Dun etc. 

 

Q4 Mention the significance of the Himalayas.

Ans The significance of Himalayas are as follows: 

  1. The Himalayas act as a climatic divide. They do not allow the cold winds from Central Asia to come into India nor do they allow the monsoons to escape into Central Asia. 
  2. They are a storehouse of forest wealth and wildlife. 
  3. They give rise to perennial rivers e.g. River Ganga. 
  4. They have a number of places of tourist attraction i.e. hill stations (Shimla, Nainital, Srinagar etc). 
  5. They are also famous for the river valleys, e.g. Kashmir valley is drained by Jhelum river and fruit orchards. 
  6. They also are well known for glaciers like Siachen, the highest battlefield. 

 

Q5 Classify the Northern plains on the basis of the variations in the relief features. 

Ans The Northern Plains are alluvial plains formed by deposition of sediments brought down by rivers from the mountains. On the basis of the variation in relief of the northern plains it can be divided into four regions.

  1. Bhabar: The rivers, after descending down from the mountains, deposit pebbles in a narrow belt of 8-16 km lying parallel to the slopes of the Shiwaliks. This is known as bhabar. The streams disappear in this belt. 
  2. Terai: Below the Bhabar belt, the streams and rivers re-emerge and create a wet, swampy and marshy region called terai. It was a thickly forested area rich in wildlife. But now the area is cleared for cultivation. 
  3. Bhangar: It is the largest part of the northern plains made up of older alluvium. This region lies above the flood plains of the rivers and presents a terrace-like feature. The soil is not fertile here, it contains calcareous deposits called kankar. 
  4. Khadar: The newer, younger deposits of the floodplains found in the lower river valley and at the mouth of the river. These are very fertile and get renewed every year by annual floods. They are suitable for intensive cultivation. 

 

Q6 Mention the significance of Northern Plains of India. 

Ans The significance of Northern Plains are:

  1. The Northern Plains of India are drained by Rivers Indus, Ganga and Brahmaputra along with their tributaries. Thus, these plains are very fertile and are a rich source of food grains in India so known as granaries of the world. 
  2. The plains are densely populated. A number of religious places are also there, e.g., Varanasi, Rishikesh, Haridwar etc. 
  3. The presence of a number of perennial rivers, e.g. Ganga, Yamuna etc. provide water for irrigation. 
  4. They have a dense network of transport such as railways and roadways. 
  5. They provide the base for early civilisations. 

 

Q7 How do the physical divisions of India complement each other? 

Ans Each physiographic region is unique in itself, but in spite of their differences they are interdependent on each other. They complement one another, in the following sense:

  1. The Northern mountains are a rich source of water and forest resources. 
  2. The Northern Plains with fertile soil are the granaries for the whole country. 
  3. The Peninsular plateau is the storehouse of mineral wealth, so it is a base of manufacturing industries. 
  4. The coastal plains provide sites for fishing and port activities.
  5. The island groups have a unique diversity in flora and fauna. 

Conclusion: None of these regions can exist without the other. Therefore, there is a geographical unity between these different regions. In other words there is a kind of unity in diversity that exists in India.
