Aeolian processes are those processes of erosion, transport, and deposition of sediments that are caused by wind at or near the surface of the earth. [1] Sediment deposits produced by the action of wind and the sedimentary structures characteristic of these deposits are also described as aeolian. [5]
Lag deposit: Angular rocks and sand grains that have been left behind during the gradual removal of finer particles by aeolian processes. Lag deposits can also form due to removal of finer particles by water. Yardangs: A protruding rock that results from a streamlined carving from consolidated material by wind abrasion by dust and sand, and ...
Loesses have been described as rich, dust-like soil. [5] Loess deposits may become very thick: at more than a hundred meters in areas of Northwestern China and tens of meters in parts of the Midwestern United States. Loesses generally occur as blanket deposits that cover hundreds of square kilometers. The deposits are often tens of meters thick.
Beach sands and river channel deposits are examples of fluvial transport and deposition, though sediment also often settles out of slow-moving or standing water in lakes and oceans. Desert sand dunes and loess are examples of aeolian transport and deposition. Glacial moraine deposits and till are ice-transported sediments.
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 ...

The dust that sits in your home can turn into tumbleweed-like dust bunnies and wreak havoc on allergies and indoor air quality. Ahead, we spoke to cleaning experts about the most common dusting ...
Changes in hydrological cycle and vegetative cover impact these patterns and have a large impact on global dust production, with dust deposition estimates ranging between 1000 and 2000 Tg/year. [2] Aeolian dust is a critical part of the iron cycle by transporting iron particulates from the Earth's land via the atmosphere to the ocean. [23]
