8.8 Wind

The wind is a force of erosion that wears down the surface of the Earth especially in regions where vegetation is scarce. 

Wind can carry fine materials, such as sand, from one place to another. When the speed of the wind decreases, these materials can pile up and form dunes. Dunes are especially common in deserts and beaches.

Fine fertile ground dust or loess is a byproduct of wind. This material is picked up from deserts and the border zones of glacial areas. The wind carries this material for thousands of kilometers, which results in the material accumulating at a certain location. Loess areas can be found in Russia, Ukraine and Germany. 

Wind can also erode rock by wearing down the lower surfaces of cliffs. Wind only erodes the lower parts of cliffs because it can only can carry particles like sand at low altitudes. 

Rock pedestals can be formed as the result of wind erosion. Their large caps and thin stems resemble mushrooms, which is why these formations are sometimes called mushroom rocks

A sand storm transports sand and other fine materials. Sand storms occasionally cause problems near desert regions.
