Which Landscape Processes Are Responsible For Loess Deposits?


Loess is mostly created by wind, but can also be formed by glaciers. When glaciers grind rocks to a fine powder, loess can form. Streams carry the powder to the end of the glacier. This sediment becomes loess.


Loess material in northern China is likely to have first formed through glacial abrasion and erosion by other geomorphic processes in mountainous areas (Sun, 2002b; Smalley et al., 2014), then was transported by fluvial and eolian processes into deserts, which act as silt and clay storage regions, rather than places where particles are formed.

Frequently Asked Questions

Which climatic condition is represented by occurrence of loess deposits?

Quaternary climatic changeDust Deposits: Loess Loess are geological deposits of silt-size mineral dust that together with paleosols (buried soils) form some of the most important terrestrial records of Quaternary climatic change.

Which erosional processes are occurring in the Loess Hills?

Iowa's Loess Hills are one of the state's and nation's unique scenic, geological, and biological resources. In addition, they are an out- standing example of two fundamental geological processes - the strong influence of past eolian or wind deposition, and erosional sculpture of the land.

Why are loess deposits used as farmlands?

Loess tends to develop into very rich soils. Under appropriate climatic conditions, it is some of the most agriculturally productive terrain in the world. Soils underlain by loess tend to be excessively drained. The fine grains weather rapidly due to their large surface area, making soils derived from loess rich.

What are the loess plains in social studies?

Loess is an aeolian sediment produced by wind-blown silt deposition, usually in the size range of 20-50 micrometres, twenty percent or less clay and the equilibrium of sand and silt components that are loosely cemented by calcium carbonate. Therefore, the loess plains are flat regions covered by such deposits.
