Desert regions exhibit lack of moisture due to excessive temperature. The impact of air is more in regions of less moisture. Topographies which are formed by the deposition of soil blown and brought by air are known as depositional topographies. 

Some of the major topographies formed by deposition performed by wind are as follows:

1. Sand dunes: These are tiny moving piles or mounds of sand, which get shifted along with wind. 

2. Ripples: These are structures which get projected on the sandy surface of the deserts, just like sea waves. 

3. Sand drifts: These are moving vertical sequences of sand on the edge of the topographic obstacle.

4. Sand levees: These are vertical sequences of sand with broad peak. 

5. Loess: Deposit of minute sand particles flown and brought by the wind are known as loess.
