Yardangs are unique desert landforms that are found in a myriad of deserts in the world including the Turkistan and the Mojahe deserts. While above height of average 2 meters, erosional process is again very low. Yardangs are streamlined forms, with a blunt upwind face and a tapering leeward projection that appears to have evolved to minimize drag. Ripple marks, known as sediment ridges, are formed when the wind blows across a sediment layer. Both processes happen over a long period of time, sometimes millions of years. Surfaces that have been worn away at by grain are called ventifacts. This triangle of land is called a delta. Topsoil is usually eroded first because it _____. Wind erosion typically occurs in any area where the soil or sand is not compacted or is of a finely granulated nature.
