What term describes the movement of dirt and dust by wind from one location to another?

• A. Wind erosion
• B. Deflation (Erosional Process)
• C. Desert pavement
• D. Glacier

Answer: (A)

Wind erosion describes how wind moves dirt and dust from one place to another. It happens when wind has enough force to lift loose particles (entrainment), transport them through the air by suspension or by bouncing along the surface (saltation), and eventually deposit them elsewhere, reshaping landscapes such as dunes and eroded surfaces. Deflation is a specific wind-erosion process that removes fine particles from the surface and can leave behind coarser material, but it’s a particular mechanism within wind erosion rather than the general term for wind-driven transport. A glacier involves ice movement, not wind-driven transport, and desert pavement is a landform created by deflation and other processes rather than the act of movement itself. So the movement of dirt and dust by wind from one location to another is described by wind erosion.
