Why is wind abrasion stronger close to the ground?
Answer and explanation
Correct answer: Because saltating sand grains mostly move at low levels
The governing concept is wind abrasion, in which moving particles strike and wear exposed rock. Sand grains commonly travel by saltation: they hop, bounce and roll near the surface rather than remaining high in the air. Their repeated impacts therefore erode the lower part of a rock more strongly, sometimes producing a pedestal or mushroom rock. The other choices describe unrelated processes.
