Which risk increases when dust deflation lowers soil elevation?

A)Accelerated desert pavement formation
B)Increased alluvial fan deposition
C)Decreased floodplain sedimentation
D)Slower chemical weathering processes

💡 Explanation

Accelerated desert pavement formation increases because wind deflation removes fine particles at the surface, leaving behind larger rocks. This process, called armoring, protects underlying soil rather than promoting alluvial deposition; therefore the answer is desert pavement.
