Which abrasive mechanism sculpts ventifacts in hyperarid environments?

💡 Explanation

Aeolian abrasion specifically shapes ventifacts in deserts where wind-blown sand particles erode exposed rock surfaces; because differing wind directions and particle sizes cause differential erosion rates, these sandblasts carve distinctive shapes rather than uniform recession.
