Features Produced by Wind Deposition

Wind deposition causes or produces the following features:

1. Dunes are accumulation of sand formed in desert by the action of wind.

Dunes are of two types:

a. Barchans are crescent shaped sand dunes, which may occur in group or individually.

b. Seifs or longitudinal dunes: These occur in the form of long, narrow and steep-sided ridges that lie parallel to the direction of the prevailing wind.

2. Loess are fine rock particles of dust blown out or carried over long distances by strong and steady winds

3. Sand sheet: This is a mass accumulation of sand in the desert when wind disperses sand evenly.
