Which stone modification results when unidirectional wind erosion ablates desert pavement?

💡 Explanation

Ventifacts form due to strong, persistent winds carrying sand and silt abrading rock surfaces; this process of aeolian abrasion creates distinct facets and forms on the windward side. This sculpturing occurs because abrasive transport is directed, rather than creating a uniform, thin coating, such as desert varnish.
