WORLD HISTORY

Detailed explanation-1: -In some parts of the world, windblown dust and silt blanket the land. This layer of fine, mineral-rich material is called loess. Loess is mostly created by wind, but can also be formed by glaciers. When glaciers grind rocks to a fine powder, loess can form.

Detailed explanation-2: -Loess is a deposit of wind-blown silt that blankets large areas of the continents. It is often light brown in color, consisting predominantly of quartz, feldspars, micas, and calcium carbonate.

Detailed explanation-3: -Loess soil formations are typically non-stony fine sand, porous silt, loose sediment material of yellowish brown colour.

Detailed explanation-4: -Loess is an aeolian sediment produced by wind-blown silt deposition, usually in the size range of 20-50 micrometers, It consists of Twenty percent or less clay and the equilibrium of sand and silt components that are loosely cemented by calcium carbonate.

Detailed explanation-5: -In summary, loess is the only parent material in a few soils and is the uppermost parent material of many soils in Indiana. It is not stratified. It commonly forms silt loam A horizons, silty clay loam or heavy silt loam B horizons, and silt or silt loam C horizons.
