Desert sand dunes primarily consist of coarse sand particles and generally contain very little silt. The strong winds that shape these dunes tend to carry away finer materials like silt, leading to a predominance of larger sand grains. However, some desert environments may have areas where silt is present, but it is not a characteristic feature of sand dunes themselves.

What does wind erosion form?
Wind erosion can form features such as sand dunes, loess deposits, and desert pavement. Sand dunes are created by the deposition of sand grains carried by the wind, while loess deposits consist of fine silt particles that settle out of the wind. Desert pavement forms when finer particles are removed by the wind, leaving behind a surface of coarser rocks and pebbles.
How are sand dunes formed in deserts?

What two formations does wind deposition create how they are different?
Wind deposition primarily creates dunes and loess. Dunes are mounds or ridges of sand formed by the accumulation of sand particles moved by the wind, typically found in desert or coastal environments. In contrast, loess is a fine, silt-sized sediment that is wind-blown and can cover large areas, often resulting in fertile soil. The key difference lies in their composition and formation processes: dunes are composed mainly of sand, while loess consists of finer particles and often forms in areas with minimal vegetation.
A stony surace called desert pavement is a common feature of many deserts Which process helps form desert pavement?
Deflation of sand and silt from the surface
How does silt taste?
Silt does not have a taste as it is a fine sediment composed of particles of sand, clay, and organic matter. However, ingesting silt can be harmful to health as it may contain contaminants and pathogens.
How does loess deposit from?
Continued high winds will pick up dust and silt particles and blow clouds of them cross-country until the wind dies down and the dust and silt fall to earth. Sometimes, especially where I live in North Idaho, the loess (luss) was formed into what look like sand dunes. Dust dunes, I guess.

Is silt smaller than sand?
