Question

• A. Gorge
• B. V-shaped valley
• C. Sink hole
• D. Mushroom rock

Answer 1

Answer:

D. Mushroom rock

A mushroom rock is an erosional landform created by wind.

Mushroom rocks are formed through a process of wind erosion, primarily in desert regions. The wind erodes softer rock layers faster than harder layers, creating a shape that resembles a mushroom, with a wider top and a narrower base. This happens because the wind continually abrades the rock, wearing away the lower part more quickly than the top, which is more resistant to erosion.

These rock formations are a clear example of deflation and abrasion caused by wind, which are common erosional processes in arid regions.
