Question

Q3. Give Geographical reasons:
1. The Barren Island is becoming conical in shape.
2. There is adifference in the formation of Meghalaya Plateau and Deccan Plateau​

Answer 1

Explanation:

1. The Barren Island is home to India's only volcanic mountain, the Barren Mountain which had been dormant for a long time. It was a central type or conical volcano where the magma had been ejected through a single central vent. This has made it more conical in shape.

2. The Meghalaya plateau is a type of block mountain. It was formed when horizontal movements of the waves within the earth's crust moved away from each other creating tension on the surface finally creating faults. This magma cools down and forms a gently rolling plateau as seen in the Deccan plateau.
