A "loess" is a type of soil deposit. It is formed by dust carried on the wind. At the end of the last Ice Age, winds blew off the retreating northern ice sheets and across the "ground up" moraine deposits left by the retreating ice.
As it did so it picked up the fine rock flower from these and dust storms formed, the dust was carried south and then deposited in great thicknesses.
These deposits are yellowish in color and China has a great deal of "loesses".
What else can I help you with?
Deposit of windborne silt and dust?
Windborne silt and dust can accumulate to form deposits known as loess. These deposits are often found in flat, arid regions and can be quite extensive. Loess deposits are important for agriculture as they are rich in nutrients and help improve soil fertility.
Do loess helps to form fertil soil?
Yes, loess deposits can help to form fertile soil due to their high content of minerals and nutrients. Over time, the fine particles of loess break down further, releasing nutrients and improving soil quality for agriculture.
What agent of erosion causes loess?
Wind is the primary agent of erosion that causes loess. Fine particles of silt and clay are carried by the wind over long distances before settling and accumulating to form thick deposits of loess.
Fine sediment deposited by wind in layers is called?
deflate
What are deposits of wind-blown rock flour called?
Deposits of wind-blown rock flour are called loess. Loess is a finely grained sediment that is usually deposited in extensive layers, often forming fertile soils when mixed with other materials.
How do sand dunes and loess deposits form?
Wind erosion and deposition may form sand dunes and loess deposits. When the wind strikes an obstacle, the result is usually a sand dune!
How do loess form and why is it important?
Loess forms by wind. It is thought that loess, a kind of silt or clay, is formed from deposits of wind-blown dust.
What is loess deposits?
Loess is deposited by wind.
How does a loses deposits form?
Your question doesn't make sense to me . . . maybe you meant, "How does a loess (luss) deposit form?" Loess is a deposit of dusty silty dirt that has been blown into an area from a different location. It often deposits in the shape of sand dunes. The "Palouse Loess Deposit" around Pullman, WA and Moscow, ID is a great example of dune-shaped loess deposits.
Deposit of windborne silt and dust?
Windborne silt and dust can accumulate to form deposits known as loess. These deposits are often found in flat, arid regions and can be quite extensive. Loess deposits are important for agriculture as they are rich in nutrients and help improve soil fertility.
What features result from deposition by wind?
Wind erosion and deposition may form sand dunes and loess deposits.
What are a common form of wind deposits in desert regions and near oceans and lakes?
loess
What are common form of wind deposits in deserts regions and near oceans and lakes?
loess
What are two types of deposits formed by wind erosion and deposition?
Sand dunes and loess deposits are two types of deposits formed by wind erosion and deposition. Sand dunes are hills of sand that form in areas with strong winds, while loess deposits are fine, wind-blown sediment that accumulates over time to create thick layers of fertile soil.
Do loess helps to form fertil soil?
Yes, loess deposits can help to form fertile soil due to their high content of minerals and nutrients. Over time, the fine particles of loess break down further, releasing nutrients and improving soil quality for agriculture.
How are the sediments in loess deposits from the sediments in a sand dune?
Loess is very fertile while sand is not
How are sediments in loess deposits from the sediments in a sand dune?
Loess is very fertile while sand is not
