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). Winds may erode , transport, and deposit materials.
Aeolian landforms, or Eolian landforms, are produced by either the erosive or depositive action of wind. These features may be built up from sand or snow , [ 1 ] or eroded into rock, snow, or ice. Aeolian landforms are commonly observed in sandy deserts and on frozen lakes or sea ice and have been observed and studied around Earth and on other ...
Saltation of sand. In geology, saltation (from Latin saltus 'leap, jump') is a specific type of particle transport by fluids such as wind or water.It occurs when loose materials are removed from a bed and carried by the fluid, before being transported back to the surface.
Aeolian landform – Landforms produced by action of the winds include: Dry lake – Area that contained a standing surface water body; Sandhill – Type of ecological community or xeric wildfire-maintained ecosystem; Ventifact – Rock that has been eroded by wind-driven sand or ice crystals; Yardang – Streamlined aeolian landform
In accordance with these agents, erosion is sometimes divided into water erosion, glacial erosion, snow erosion, wind (aeolian) erosion, zoogenic erosion and anthropogenic erosion such as tillage erosion. [1] Soil erosion may be a slow process that continues relatively unnoticed, or it may occur at an alarming rate causing a serious loss of ...
Aeolian or eolian (depending on the parsing of æ) is the term for sediment transport by wind. This process results in the formation of ripples and sand dunes . Typically, the size of the transported sediment is fine sand (<1 mm) and smaller, because air is a fluid with low density and viscosity , and can therefore not exert very much shear on ...

Hargraves exhibits evidence of modification by aeolian processes over time. Transverse aeolian ridges predominate in a NNW-SSE orientation atop the older ejecta unit (interpreted as a lithic impact breccia), implying the presence of a longstanding prevailing wind. [2] A large erg is also present within the crater's topographic basin. [8]
