4. Wind

Like water and glacier, the wind is also an important agent of erosion and deposition. Wind erosion is much apparent, particularly in the deserts. Let's look at some of the important erosional and depositional feature/landforms of wind.

 

Mushroom rock: As the name suggests, the shape of the rock will be in the shape of a Mushroom. This shape of rocks is mostly seen in deserts because the wind carrying sand erodes the lower section of the rock more than that of the upper part. This is because the speed of the wind is higher close to the surface of the earth.

 

 

Inselberg: A small, rounded hill, knob, ridge, or mini-mountain that rises abruptly from relatively flat surroundings. It is also called a Monadnock.

 

Sand dunes: Sand dunes are nothing but sandhills. When there is a strong wind, it carries the sand away. But, when the wind speed reduces, it deposits the sands in a low hill-like structure called sand dunes.
 
Barchans: The crescent-shaped sand dunes are called, Barchans.

 

 

Loess: Windblown silt and clay, deposited as a layer over a large area, are called loess. Loess deposits make very fertile soils in many regions of the world.
