Which process sculpts ventifact shapes preferentially on upwind faces?

A)Differential aeolian abrasion
B)Localized salt crystal growth
C)Cyclical freeze-thaw weathering
D)Alternating hydration-dehydration fracturing

💡 Explanation

Aeolian abrasion preferentially erodes upwind surfaces because wind carries abrasive particles; therefore differential aeolian abrasion sculpts those faces, rather than chemical weathering altering all exposed regions equally or freeze-thaw affecting subsurface layers.
