Which outcome do anisotropic winds and airborne abrasives create?

💡 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.
