Which spatial outcome results when desert vegetation stabilizes parabolic dune arms?

A)Deflation hollow formation decreases sharply
B)Ventifact abrasion rate increases steadily
C)Loess sediment plume trajectory increases
D)Barchan migration velocity rises swiftly

💡 Explanation

Deflation hollow formation decreases because vegetation anchoring increases surface cohesion, reducing wind erosion; therefore, hollow development slows noticeably, rather than intensifying ventifact abrasion or altering distant loess movements since surface deflation ceases within hollows.
