Answer 2

• Wind is an active agent of gradation mainly in the desert. It blows unchecked due to lack of vegetation. The sand and dust particles are carried over greater distance. These get deposited when the wind velocity reduces or when there is an obstruction in the path of the wind

• In deserts, wind picks up small particles and leaves behind larger rocks to form desert pavement. Moving sand may sand blast rocks and other features to create ventifacts. The sand is transported until it is deposited in a sand dune.

Hence, we could conclude that Dunes and Rock Pedestals are features produced by wind in the desert.
