A prominent erosional landform of wind action is called a "yardang". A yardang is a streamlined ridge that is created by the erosion of windblown sedimentary rocks. When strong winds blow across the landscape, they can cause the rocks to become eroded and sculpted into elongated ridges with a sharp, pointed crest and steep slopes. Yardangs are typically found in arid regions and are often aligned with the direction of the prevailing wind. They are an important feature of desert landscapes and can range in size from a few meters to several kilometers in length.
