Which mechanism shapes ventifact development given limited dune sand?

💡 Explanation

Aeolian abrasion creates ventifacts where constant wind-driven sand impacts exposed rock surfaces, because the repetitive impact grinds and polishes the rock preferentially, therefore forming distinct facets rather than other weathering patterns.
