Which erosional outcome results when deflation affects playas?

A)Formation of expansive desert pavement
B)Increased deposition near ephemeral channels
C)Accelerated chemical weathering processes
D)Stabilization of longitudinal dune formations

💡 Explanation

Deflation removes fine sediments, winnowing smaller particles and leaving behind larger ones; desert pavement develops because removal of the fines leaves a surface layer of tightly packed larger rocks. Therefore, pavement forms rather than deposition, weathering change or dune alteration.
