Question

Mention the various features formed by wind erosion.

Answer 1

Some of the erosional landforms of wind are

• Mushroom rocks

1. When a rock’s bottom is soft, the sand-laden winds blow against it and wear it down.
2. By the constant wearing down action of the wind, the bottom gets eroded away to form a mushroom like structure.

• Inselbergs:

1. Certain hard rocks like igneous rocks are more resistant to wind action.
2. Such isolated residual hills rising abrupt by from their surroundings are turned as inselbergs.

• Yardangs:

1. In arid regions certain rocks have hard and soft layers arranged vertically.
2. When winds blow over these rocks, the soft layers get eroded leaving irregular crests. These are called yardangs.
