What two formations does wind deposition create how they are different?

Wind deposition primarily creates dunes and loess. Dunes are mounds or ridges of sand formed by the accumulation of sand particles moved by the wind, typically found in desert or coastal environments. In contrast, loess is a fine, silt-sized sediment that is wind-blown and can cover large areas, often resulting in fertile soil. The key difference lies in their composition and formation processes: dunes are composed mainly of sand, while loess consists of finer particles and often forms in areas with minimal vegetation.
