Which mechanism produces flattened facets on desert ventifacts?

💡 Explanation

Differential abrasion creates flattened facets because wind concentrates abrasive particles at specific angles, therefore shaping rocks selectively, rather than uniform weathering or temperature fracturing, which affects the entire rock surface.
