Give geographical reasons:Mushroom rocks have broad tops.

Answer»

Mushroom rocks have broad tops because-

1. The high rising rocks in the path of the wind are attacked by the sand that moves with the wind. 

2. Winds and the particles they carry, attack the base of an individual rock. 

3. The larger top part is not eroded as much as the basal part since, the particles carried by the wind being heavy are not uplifted up to the top portion of the rock. 

4. The particles at medium height are smaller but their velocities are high. Hence, their impact is more. 

5. As a result, the portion of rock at medium height is eroded more and the rock as a whole gets the shape of a mushroom.
