Question

describe briefly the four main structural units of Indian landmass .​

Answer 1

HEY MATE !!!!!!!______________

Millions of years ago, the Peninsular Plateau region (the oldest landmass) was a part of the Gondwana Land which covered India, Australia, South Africa, and South America. Over hundreds of years of shifting landmass and ocean currents broke this landmass into multiple pieces.

One such piece- the Indo-Australian plate started shifting northwards, where it collided with the Eurasian plate (now Europe). Consequently, this collision caused the landmass to fold and become, what we know as the Himalayas today.
