← GeographyWhich primary feature results when aeolian Abrasion transforms desert rocks?
A)Ventifact formation on exposed surfaces✓
B)Lateral migration shifts of barchan dunes
C)Dissolution widens limestone karst cliffs
D)Suspension concentrates silt to fertile soil
💡 Explanation
Ventifacts' angular shapes on rocks form because aeolian abrasion, caused by wind-blown particles, erodes rocks. The wind selectively polishes and sculpts exposed surfaces; this mechanism is "abrasion", therefore, ventifacts appear, rather than dune migration or karsts.
