Why is the base of a mushroom rock narrower?
Answer and explanation
Correct answer: Because sand abrasion by wind is stronger near the ground
A mushroom rock, or pedestal rock, develops in a desert where wind-driven sand is concentrated close to the ground. This sand abrades the lower part of an exposed rock much more intensely than the upper part, producing an undercut and a narrow base with a wider cap. Waves, river deposition, and glacial addition do not explain this shape. Hence option D gives the governing process and is correct.
