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 and are effective agents in regions with sparse vegetation , a lack of soil moisture and a large ...
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 ...
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
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 ...

Aeolian processes pertain to the activity of the winds and more specifically, to the winds' ability to shape the surface of the Earth. Winds may erode, transport, and deposit materials, and are effective agents in regions with sparse vegetation and a large supply of fine, unconsolidated sediments .

Cross-bedding in lithified aeolian sand dunes preserved as sandstone in Zion National Park, Utah. A lithified (consolidated) sand dune is a type of sandstone that is formed when a marine or aeolian sand dune becomes compacted and hardened. Once in this form, water passing through the rock can carry and deposit minerals, which can alter the ...
