Wind deposition can result in dunes and loess deposits.
Wind Erosion and Deposition continued DEFLATION Wind can blow tiny particles away from larger rock pieces during deflation. Deflation happens when wind removes the top layers of fine sediment or soil and leaves behind larger rock pieces. Deflation can form certain land features. It can pro-duce desert pavement, which is a surface made of peb-
