← GeographyWhich outcome do anisotropic winds and airborne abrasives create?
A)Ventifact formation on exposed surfaces✓
B)Loess deposit accumulation in basins
C)Parallel dune alignment transverse valleys
D)Dissolution of carbonate rock features
💡 Explanation
Ventifacts form because aeolian abrasion preferentially erodes rock facets facing prevailing winds through the sandblasting mechanism. This carves distinctive shapes into rock rather than forming loess or dunes, because the effect is erosional rather than depositional.
