what do you call the erosion of sediment by the wind?
a. deflation
b. drifting
c. deposition****
d. plucking
correct or wrong?
Deposition is when water slows down and silt settles to the bottom beneath
ty
this is only for a study guide so
The correct answer is a. deflation.
Deflation is the process of wind removing and carrying away fine particles of sediment such as sand, silt, and dust, leaving behind coarser and heavier material. This process is commonly observed in arid or desert environments where there is little vegetation to hold the soil in place. The wind blows across the surface of the sediment, lifting and carrying away the smaller grains, which leads to erosion and the exposure of larger particles.
Drifting, on the other hand, generally refers to the movement of sand dunes and the shifting of sand in response to wind. It is related to deflation but is more specifically focused on the movement and accumulation of windblown sediment.
Deposition, the option you selected, is incorrect in this case. Deposition refers to the process by which sediment carried by wind, water, or ice is dropped or added to a new location. It is the opposite of erosion.
Plucking is a process associated with glacial erosion, not wind erosion. It occurs when glaciers pick up and pluck out pieces of rock from the underlying bedrock as the ice flows downhill. So, it is not the correct answer for this question.
Therefore, the correct answer is a. deflation.
