The formation of "Mushroom Rocks" in deserts is an example of which of the following?

Solution (By Examveda Team)

Mushroom rocks, also known as pedestal rocks, are formed in deserts due to the process of abrasion. Abrasion occurs when wind-blown sand and particles strike the surface of rocks, eroding the softer material at the base more than the top.

Over time, the differential erosion results in the base becoming narrower while the upper portion remains relatively wider, giving the rock a mushroom-like shape.

Erosion is a broader process that includes abrasion but also involves the removal of material by wind, water, or ice.

Contraction is not involved in the formation of mushroom rocks.

Attrition refers to the wearing down of particles during transport, not the shaping of stationary rock formations.

Thus, the formation of mushroom rocks is an example of abrasion.
