Question
Describe how the Himalayas were formed.
✓
Answer
The oldest landmass of India (peninsular part) was a part of Gondwana land.
Gondwana land included India, Australia, South Africa and South America as one single landmass.
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.
The Northward drift resulted in the collision of the plate with the much larger Eurasian plate.
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.
The Himalayas represent a youthful topography with high peaks, deep valleys and fast following rivers.
