Which wind erosion process dislodges more particles and moves the most soil?

• A. Saltation
• B. Suspension
• C. Creep
• D. Deflation

Answer: (A)

In wind erosion, the process that dislodges the most particles and moves the greatest amount of soil is the hopping motion of grains that collide with the surface, creating a sandblasting effect. As wind lifts grains, they bounce along the surface and repeatedly strike other grains, ejecting them and sustaining a high flux of material. This continuous impact-driven dislodgement drives the majority of soil transport under typical wind conditions, making it the dominant mechanism for both surface disturbance and overall movement. Suspension can carry very fine particles high into the air over long distances, but the number of particles involved in suspension at any moment is usually less than the mass mobilized by saltation near the surface. Creep involves larger particles rolling or sliding and occurs more slowly, contributing less to total transport. Deflation refers to the removal of loose surface material but doesn’t describe the primary transport process as effectively as saltation.
