Aeolian processes are the erosion, transport and deposition of sediment carried out by wind. Deflation strips loose fine grains from a surface, abrasion and attrition wear and round the grains wind carries, and the same wind builds the sand back up as dunes, sand sheets and windblown loess. Water erodes more material worldwide, but wind dominates where vegetation is sparse and sand is exposed, chiefly deserts and their margins.

1. Aeolian Processes (Wikipedia)
Wikimedia FoundationIntroduction, definition and setting
Although water is a much more powerful eroding force than wind, aeolian processes are important in arid environments such as deserts.
Deposition section, process-type
Wind is very effective at separating sand from silt and clay. As a result, there are distinct sandy (erg) and silty (loess) aeolian deposits.
Introduction, alias
Aeolian processes are those processes of erosion, transport, and deposition of sediments that are caused by wind.

Barchans "face" the wind, appearing convex, and are produced by wind action predominantly from one direction.

The lake was formed by aeolian processes after tectonic upwarping occurred to the south subsequent to the end of the Pleistocene epoch.

As a shifting sand desert, sand dunes constantly shift under the influence of the wind.

A yardang is a streamlined protuberance carved from bedrock or any consolidated or semiconsolidated material by the dual action of wind abrasion by dust and sand and deflation (the removal of loose material by wind turbulence).
