Скачать или смотреть Aeolian (Arid & Deserts) Geomorphology | Physical Geography with Professor Patrich

This lecture introduces the categorization of aridity, and landforms found in arid landscapes. Topics will include erosion, transportation, and the deposition of material, and the features developed by those processes. We also discuss how sand moves, the anatomy of dunes, and how to identify six different dunes in the field.

Aeolian processes, also spelled eolian, 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 supply of unconsolidated sediments. Although water is a much more powerful eroding force than wind, aeolian processes are important in arid environments such as deserts.

The term is derived from the name of the Greek god Aeolus, the keeper of the winds.
