Wind erosion and deposition may form sand dunes and loess deposits. When the wind strikes an obstacle, the result is usually a sand dune!
Loess is the term given to silt that accumulates due to windblown dust. It is usually highly porous.
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.
The most common wind deposits are sand dunes and loess. Sand dunes are typically found in deserts and coastal areas, while loess deposits are made up of fine-grained sediments that are often found in regions with strong winds, like the Great Plains of North America and parts of China.
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.
One descriptor would be 'an aeolian deposit. Which means a deposit caused by wind. An alternative would be the name Loess, which means the same thing. Downwind of a desert region, Loess deposits may be many tens of metres in thickness.
