Which outcome results from wind-driven abrasion over time in arid environments?

💡 Explanation

Ventifacts arise from abrasion, a form of Aeolian erosion. The wind-driven particles erode exposed rock surfaces due to abrasive impact. This results in the smoothing and shaping of rocks into ventifacts, because differential erosion grinds specific planes of wind exposed rocks, rather than uniform weathering which could produce rounded surfaces or deflation hollows.
