Q.2. Answer the following questions briefly

(i) What are tectonic plates?


The convectional currents below the Earth’s crust split the crust into a number of pieces. These pieces are called tectonic plates. e.g., Eurasia plate, Indo Australian plate etc.

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

Q.3. Distinguish between
(i) Converging and diverging tectonic plates.

Answer: Difference between Converging plates and Diverging plates.

Converging Tectonic PlatesDiverging Tectonic Plates
When tectonic plates move towards each other, they are called converging plates.When tectonic plates move away from each other, they are called diverging plates.
They collide or crumble or one of them slides under the other while moving towards each other.They do not collide or crumble while moving away from each other.
Converging plates cause folds.Diverging plates cause fractures in the crust.

Q.4. Describe how the Himalayas were formed.


(a) The oldest landmass of India (peninsular part) was a part of Gondwana land.

(b) Gondwana land included India, Australia, South Africa and South America as one single landmass.

(c) Convectional currents split the crust into a number of pieces, thereby leading to the drifting of the Indo Australian plate after being separated from the Gondwana land towards the North.

(d) The Northward drift resulted in the collision of the plate with the much larger Eurasian plate.

(e) Due to this collision the sedimentary rocks which were accumulated in the geosyncline known as the Tethys, were folded to form the mountain systems of Western Asia and Himalaya.

(f) The Himalayas represent a youthful topography with high peaks, deep valleys and fast following rivers.

Q.6.  Give an account of the Northern plains of India.


(a) The Himalayan uplift out of the Tethys sea and subsidence of the Northern flank of the peninsular plateau resulted in the formation of a large basin. In course of time, this depression gradually got filled with deposition of sediments from rivers flowing from the mountains in the north and led to formation of the fertile Northern plains.
