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 landforms preserved in the formation range from damp sandsheet and lake paleosol (fossil soil) beds to thin, chaotically arranged dune sets to equilibrium erg construction, with dunes 300 to 400 meters (980 to 1,310 ft) wide migrating over still larger draas. The draas survived individual climate cycles, and their interdunes were sites ...
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

A draa is a very large aeolian landform, with a length of several kilometers and a height of tens to hundreds of meters, and which may have superimposed dunes. [23] Dunes are made of sand-sized particles, and may consist of quartz, calcium carbonate, snow, gypsum, or other materials.
A yardang near Meadow, Texas) (USDA photo Yardangs in the Qaidam Desert, Qinghai Province, China.. 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).

The surface of Venus is dominated by geologic features that include volcanoes, large impact craters, and aeolian erosion and sedimentation landforms. Venus has a topography reflecting its single, strong crustal plate, with a unimodal elevation distribution (over 90% of the surface lies within an elevation of -1.0 and 2.5 km) [ 1 ] that ...
Strictly speaking, an erg is defined as a desert area that contains more than 125 km 2 (48 sq mi) of aeolian or wind-blown sand [3] and where sand covers more than 20% of the surface. [2] Smaller areas are known as "dune fields". [ 4 ]
