Following repeated seasonal flash floods across alluvial fans in arid regions, which outcome directly results related to local aeolian processes?

A)Extensive deflation hollow formation
B)Increased loess sediment deposition
C)Accelerated ventifact abrasion rates
D)Stabilized dune migration patterns

💡 Explanation

Seasonal floods remove fine sediments, leaving coarser material; subsequent winnowing by wind causes deflation. Deflation hollow formation occurs because wind selectively erodes unconsolidated surface material, therefore deepening the depression, rather than deposition.
