What is the importance of the Himalayas? The Himalayas form a natural boundary of the Indian sub continent. Since long they have formed a formidable barrier to the free movement of man. The Passes of the Himalayas are very high and in winter remain covered with snow.
One of the greatest diagnostic features of geomorphology is the character of river cross profiles. The cross-profile of the Himalayan Rivers is marked by gigantic gorges especially in the higher Himalayas.
The Himalayan Region extends along the North of India. It extends from Pamir to the eastern end of Arunachal Pradesh. Himalayas are the longest and the highest mountain range in the world.
