Question

which process wears away tall sandstone rock formations due to wind?
abrasion
deflation
impact
plucking

Explanation:

Abrasion is the process where wind - blown sand and other particles collide with rock surfaces, gradually wearing them away. Deflation is the removal of loose, fine - grained sediment by wind (not wearing away rock formations). Impact is a more general term and not the specific wind - related process for wearing away rock. Plucking is related to glacial action (ice picking up rocks), not wind.

Answer:

abrasion
