Question

Discuss the landforms created by winds.

Answer 1

Instructions:

• Explain mushroom rocks
• Explain sand dunes

Solution:

• Mushroom rocks :

In desert areas, a large amount of sand is lifted by fast moving winds and these sand particles move from one place to another with winds.
Now when a big rock comes in its way, these sand particles present in the wind, erode the surface of rocks over a period of time.
As the sand particles in wind blow closer to the ground, the lower part of the rock gets eroded more as compared to the upper part.
Now the landform looks like a giant mushroom, this is why we call these rocks as mushroom rocks.

• Sand dunes :

These are depositional landforms created when winds transport eroded particles from one place to another.
After erosion, when winds stop blowing, sand particles get deposited on the ground forming mounds or low-hill like structures which are called sand dunes.
Sand dunes are temporary structures as they change their shape according to blowing winds
