What is the primary geomorphic agent responsible for the formation of yardangs and zeugen?

💡 Solution & Explanation

Yardangs and zeugen are classic erosional landforms sculpted predominantly by wind abrasion and deflation in hyper-arid desert terrains. Glacial action or fluvial deposition produces completely different topographic features such as moraines and alluvial fans rather than wind-sculpted ridges. Wind erosion creates yardangs as sharp, streamlined elongated ridges parallel to the prevailing wind direction.
