deposition
Yes, sand dunes are loose sand carried and deposited by wind from one place to another.
Deposition
Three landforms created by wind erosion and deposition are Dunes, Deflatation Hollows, and Desert Pavement.
Sand dunes, for one
Sand dunes are not formed by the process of erosion, they are formed by the process of aeolian deposition.
Wind erosion and deposition may form sand dunes and loess deposits.
Deposition
Deltas are created by pieces of rock being weathered, washed away by erosion and deposition at the mouth of the river where it meets an ocean. Beaches are created by deposition of sand by waves. Dunes are created by erosion of sand by wind.
I am going to say sand dunes and loess deposits are two types of deposits formed by wind erosion.
No, they are examples of deposition, not erosion.
Five example of deposition are: beach sand, sand dunes, river delta, river silt, and sediments. Another example of deposition is wind picking up sand.
