Sagot :
Loess is assumed to have primarily glacial and periglacial origins in Europe and North America.
Where does loess come from?
Loess is created primarily by wind and is also formed by glaciers. Glaciers can turn rocks into a fine powder, which can lead to the development of loess. Streams carry the glacier's terminus's powder. This sediment is converted into loess.
Loess was formed in North America from both glacial and nonglacial causes, but it is often connected to the floodplains of large, braided rivers and to the outwash deposits of the Laurentide ice sheet; parts of the Mississippi River basin may have loess up to a depth of 20 meters.
Why is loess essential and how does it form?
The majority of loess is made up of coarse silt-sized quartz particles with a diameter of 20–63 m, however certain desert loess deposits can contain fine sands with an 80 m or less diameter. Loess is made up of large amounts of wind-blown dust that have been captured, laid down, and preserved on specific terrain.
