← GeographyWhich mechanism roughens desert pavement where ventifacts originate?
A)Salt crystal weathering by haloclasty
B)Aeolian abrasion from particle collisions✓
C)Sheet flow erosion during rare storms
D)Frost action following dew formation
💡 Explanation
Aeolian abrasion polishes upwind rock faces because wind-transported sand erodes the surfaces; therefore smooth, faceted ventifacts form on desert pavement, rather than continuous dust cover due to finer particles only.
