They are common in coastal areas. Star Dunes - are dunes with several arms and variable slip face directions that form in areas where there is abundant sand and variable wind directions. Wind Blown Dust - Dust consists of silt and clay sized particles that are often packed together with smooth surface. Such packed dust is difficult to remove by wind erosion alone, unless the surface is very dry or is disturbed. When dust it is disturbed, dust storms may develop, and dust may be transported by the wind over large distances.
Most soil contains some silt and clay particles deposited by the wind.
A large deposits of wind deposited dust is called loess . Much loess was derived from debris left by glacial erosion. Dust in Ocean Sediments and Glacial Ice. As a result, much of the fine grained continent-derived sediment that reaches the abyssal plains of the oceans was originally transported by winds or icebergs. If ejected high enough, such ash can become suspended in the wind and carried for long distances.
