Which mechanism transforms desert rocks into aerodynamic ventifacts?

💡 Explanation

Wind abrasion creates the characteristic shape; because particles in saltation act like a sandblaster, preferentially eroding windward faces. Deflation causes transport of the weathered minerals; therefore abrasion is the correct answer rather than chemical dissolution, deposition, or thermal stress.
