Loess is an erosional product carried by the wind from adjacent deserts, from frost-pulverized outwash of glaciers (during the Pleistocene epoch), or from the floodplains of glacier-fed streams. In some parts of the world, windblown silt blankets the land.

Loess landscapes, such as the Great Plains, are usually a sign of past glacial activity. Fertile area consisting of Mesopotamia and the lands facing the Mediteranian. As the distance from the source increases, the grains size deposited decreases. Loess can be made up of silt and loamy particles up to 50% and of clay particles up to 10%. Studies of particles transported by wind from plains recently denuded by tillage show that the material is sorted to about the same degree as loess. History. World History.
