 Describe how the Himalayas were formed.

Solution
t is true to say that the major areas of the Himalayas have been formed by folding while minor physical features in them have been the result of weathering and other agents of changes. The statements can be proved by the following evidences :

1. It has been learned that the Himalayas had been formed by the internal forces in various phases of movements. It had been uplifted from the great Geosyncline known as Tethys sea in the folded form. These uplifted ranges had been denuded by the weathering and the other agents of changes such as rivers and glaciers. These agents of changes carved the minor physical features such as gorges, U-shaped valleys, hanging valleys and ridges. The Indus gorge is the result of erosion and weathering.

2. Many U-shaped and hanging valleys found in this region are the result of erosional work of glaciers and ice.

3. The high order complexities in the relief features of the Himalayas were achieved by the various processes of weathering and cycle of erosion.

4. The fertile valley of Kashmir represents the depositional work of the agents of changes.

5. The rivers rising from Himalayas such as Ganga, Indus and their tributaries are busy is carving the minor physical features.

6. The snow-capped peaks of Himalayas represents the work done by earth movements.
