Work of wind

Work of wind: An active agent of erosion and deposition in the deserts is wind. In desert you can see rocks in the shape of a mushroom. Commonly called mushroom rocks. Winds erode the lower section of the rock more than the upper part. Therefore, such rocks have narrower base and wider top.

When the wind blows, it lifts and transports sand from one place to another. When it stops blowing the sand falls and gets deposited in low hill- like structures. These are called sand dunes.

When the grains of sand are very fine and light, the wind can carry it over very long distances. When such sand is deposited in large areas, it is called loess. A large deposit of loess is found in china.
