2 Answer the following questions briefly. 

(i) What are tectonic plates? 

Answer: According to Plate Tectonic Theory, the earth's crust is made up of seven major plates and a few minor ones.

We refer to these as tectonic plates. A tectonic plate, also known as a lithospheric plate, is a large slab of solid rock with an uneven form that is often made up of both continental and oceanic lithosphere. The Pacific and Antarctic Plates are among the biggest plates, although they may range in size from a few hundred to thousands of kilometers broad. Additionally, there is a wide range in plate thickness, from less than 15 km for young marine lithosphere to 200 km or more for old continental lithosphere.

(ii) Which continents of today were part of the Gondwana land?

Answer; The Peninsular region, the oldest landmass, was a part of Gondwana land. India, Australia, South Africa, South America, and Antarctica were all included in the Gondwana landmass as a unified geographical mass.

(iii) What is the bhabar?

Answer: The Northern plains can diverge into four regions. Pebbles are left behind by rivers as they flow down from the mountains in a thin band that is 8 to 16 km wide and runs parallel to the Shiwaliks' slopes. It is called bhabar. The bhabar belt is where all the streams end or disappear. 

(iv) Name the three major divisions of the Himalayas from north to south. 

Answer: The following are the three major divisions of the Himalayas from north to south; 

  • The Great or Inner Himalayas or Himadri (The Northernmost range) 

  • Himachal or Lesser Himalaya (Middle Himalayas) 

  • Shiwaliks ( Outer Himalayas)

(v) Which plateau lies between the Aravali and the Vindhyan ranges? 

Answer: The plateau between the Aravali and Vindhya ranges is known as the Malwa Plateau. The Malwa area, which stretches from modern-day western central Madhya Pradesh to south-eastern Rajasthan, was formerly a part of Ujjain, which has volcanic origins. The plateau has an average elevation of 500 meters and descends towards the north. The Chambal ravines are located in the north of this plateau, which is rolling. It is traversed by the Mahi, Chambal, and Betwa rivers, and the flora is large of the savanna variety. Because of its volcanic origins, the area has a lot of black soil.

(vi) Name the island group of India having coral origin

Answer: Lakshadweep is the island group of India formed from coral. They are a particular variety of coral reefs that are round or horseshoe-shaped and are referred to as atolls. Lakshadweep's coral reefs are situated in the southern Indian Ocean, off the coast of Kerala.

3. Distinguish between 

(i) Converging and diverging tectonic plates 

 

Converging Tectonic Plates 

Diverging Tectonic Plates 

In converging, the tectonic plates come towards each other. 

In divergent, the tectonic plates move away from each other. 

The plates collide, crumble or slide below the other. 

It moves away from each other hence they don’t collide or crumble. 

It results in folding

It produces cracks or fractures on the earth’s surface. 

Example Oceanic Nazca Plate subducts underneath the continental South American Plate at the Peru–Chile Trench.

Example: The East African Rift in eastern Africa and the Red Sea Rift.

 

(ii) Bhangar and Khadar 

 

Bhangar 

Khadar 

Bhangar is an old alluvial soil 

Khadar is a new alluvial soil 

Mainly found at a distance from the river basin

It is found close to the river basin 

Not suitable for agriculture as it is less fertile 

Suitable for agriculture as it is fertile

 

(iii) Western Ghats and Eastern Ghats 

 

Western Ghats 

Eastern Ghats 

It lies parallel to the Malabar Coast of the Peninsular Plateau 

It lies parallel to the Coromandal Cost of the Peninsular Plateau 

It is continuous and regular it can be only crossed through passes. 

It is irregular and discontinuous and is dissected by the river which drains into the Bay of Bengal

The average elevation is 900-1600 meters 

The average elevation is 600 meters 

Anai Mudi and Doda Betta are the highest peaks 

Mahendragiri is the highest peak 

 

4. Describe how the Himalayas were formed. 

Answer: 

(A) India's oldest landmass, the peninsular portion, was formerly a part of the continent known as Gondwana, which also encompassed Australia, South Africa, South America, and South Asia.

(b) Convectional currents caused the earth's crust to break up into a number of pieces, which caused the Indo-Australian plate to drift away from Gondwana land and toward the north.

(c) Due to the northward migration, this plate collided with the much larger Eurasian plate.

(d) As a result of this collision, the sedimentary strata that had collected along the Tethys geosyncline were bent to create the mountain ranges in west Asia and the Himalayas.

(e) With its lofty peaks, vast valleys, and swift rivers, the Himalayas have a young topography.
