Discuss the geological structure of India. 

Answer: Geological structure of India: 

1. India is part of ancient continent called
Gondwanaland which is divided into many plates. One such Indo-Australian plate moved towards the north and collided with Euro-asian plate and thus
resulted in rising to the present day Himalayas. 

2. To the south of Himalayas a basin was formed. It was filled with alluvium brought by the rivers and thus forming North Indian plains. 

3. During Himalayas formation, two major events affected the plateau. An extensive volcanic eruption took place in the north-west part of the plateau. 

4. The western part subsided and the Indian Ocean advanced and occupied the depression. It led to the rise to the Bay of Bengal and the Arabian sea.
