← GeographyWhich 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.
