Which erosional feature is formed in a desert due to the action of wind? Explain its formation.
Answers
Windblown silt and clay deposited layer on layer over a large area form loess (Figure below). Loess deposits form downwind of glacial outwash or desert, where fine particles are available. Loess deposits make very fertile soils in many regions of the world.

Explanation:
Wind erosion is composed of:
Abrasion – Very small particles of rocks are hit against the rock surfaces which lead to the formation of some characteristic features of desert like Zeugens, Rock pedestals and Yardangs.
Deflation – The depressions are formed when wind blows away the wastes of rocks to distant areas. The movement of particles causes the surface to get lowered and forms depressions.
Attrition – When rock particles rub against each other and wear down and break down into much smaller particles, it is called attrition.
Wind deposition
Dunes – These are the result of deposition of rock wastes which get deposited in the form of large mounds. These mounds are either ridge shaped or crescent shaped.
The presence of water is quite low in desert but still when combined with the power of wind, it forms various shapes and landforms in the desert.
