WORLD HISTORY

Detailed explanation-1: -Encyclopedic entry. In some parts of the world, windblown dust and silt blanket the land. This layer of fine, mineral-rich material is called loess.

Detailed explanation-2: -Loess is a periglacial or aeolian (windborne) sediment, defined as an accumulation of 20% or less of clay and a balance of roughly equal parts sand and silt (with a typical grain size from 20 to 50 micrometers), often loosely cemented by calcium carbonate.

Detailed explanation-3: -Loess is formed from high accumulation of windblown dust that is trapped, deposited and preserved on certain landscapes. After deposition, dust will be altered by weathering and soil-forming processes, and is held in place by vegetation.

Detailed explanation-4: -Loess is a yellowish, predominantly silt-sized sediment that is rich in calcium carbonate and most abundant in semi-arid regions of inner Eurasia [1].

Detailed explanation-5: -Loess is a kind of fine dirt or dust that’s made up of silt, sand, and clay. The wind blows loess around until it settles and, over time, accumulates in one area. Where loess settles, the resulting soil tends to become very fertile, and to be distinctive for its yellowish-brown color.
