Describe loess deposits, their formation, distribution, and their importance
What will be an ideal response?
In many parts of the world, wind transported fine-grained sediments of clays, silts, and fine sands) have accumulated in unstratified, homogeneous deposits called loess. These deposits form a thicket blanket of material that covers previously existing landforms. The materials that contribute to loess deposits are often glacial or periglacial in origin, especially alluvial deposits in meltwater, (North American and Europe) or from windblown desert sediments (China). Because of the strength and internal coherence, loess weathers and erodes into steep bluffs. Large loess deposits are found in the central U.S. and Pacific Northwest, in parts of Northern Africa, large parts of Europe In Asia (primarily in China) and in large parts of Argentina in South America.
Loess areas make good agricultural land and have even been carved for human dwellings.
