    How does wind action change the surface in deserts?

    Answer:

    Wind is responsible for erosion in the deserts. When it blows across the land, it picks up tiny particles of loose sand. These sand particles strike forcefully against the rocks in case of strong winds or storms. This is called sandblast. Mushroom rocks are formed due to sandblasting as the lower part of the rocks erode more quickly as compared to the top giving the rock a mushroom shape. When sand is deposited at a place, sand dunes are formed. Thus constant wind action shapes the outer surface in deserts into different landforms.
