Question

Although sand dumes are thr best known wind deposits accumulations of loess are very significant in some parts of the world. What is loess? Where are such deposits found? What are the origins of this sediment

Answer 1

Answer:

They are deposits of silt and mud carried by the wind.

They are found in regions close to but outside areas of glaciation.

There are deposits in Europe, North America, China, and Argentina.

Explanation:

Loess was first discovered and coined in Europe and refers to an important component of the soils of the European Plain. Loess consists of particles of silt, clay, and mud that have been carried by the wind and eventually deposited to form extensive formations.

Loess layers are not only deep but also conducive to agriculture as they are also fertile. Perhaps the most common source of loess is the glacial activity since the movement of glaciers produces a large amount of finely ground sediment on the fringes that is later picked up by the wind.
