This sedimentbecomes loess. Small whirlwinds, called dust devils, are common in arid lands and are thought to be related to very intense local heating of the air that results in instabilities of the air mass. Dust devils may be as much as one kilometer high. Eolian deposition Wind-deposited materials hold clues to past as well as to present wind directions and intensities. This often happens when the wind has to move over, or around, an obstacle. A rock or tree may cause wind to slow down. As the wind slows, it deposits the largest particles first. Different types of deposits form depending on the size of the particles deposited. Deposition of Sand. When the wind deposits sand, it forms small hills of sand.Aeolian processes, also spelled eolian, [1] pertain to wind activity in the study of geology and weather and specifically to the wind's ability to shape the surface of the Earth (or other planets ).

Debris in the glacial environment may be deposited directly by the ice or, after reworking, by meltwater streams (outwash).The resulting deposits are termed glacial drift.
