← GeographyFollowing 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.
