How do Yardangs form?

Yardangs form through the process of erosion by wind, primarily in arid and semi-arid regions. The wind carries fine particles that wear away softer rock layers, while harder rock remains relatively intact, creating elongated ridges or streamlined shapes. Over time, this differential erosion leads to the distinctive morphology of yardangs, which can vary in size and orientation depending on wind direction and geological conditions.
