Which of the following geomorphic agents is primarily responsible for the formation of yardangs and zeugus in arid and semi-arid regions?

💡 Solution & Explanation

Yardangs and zeugus are classic desert landforms shaped by aeolian processes, where wind-driven sand particles abrade and deflate less resistant rock strata while leaving harder layers intact. Glacial action creates U-shaped valleys and moraines, whereas fluvial processes carve river valleys. Wind erosion is most effective in arid regions due to sparse vegetation cover and loose sediment supply.
