1
Deserts and Their Distribution
- A desert receives generally below 25 cm rainfall per annum.
- Deserts occupy about 30 per cent of the earth's surface area.
- Most deserts are found on the western margins of continents between 20° and 30° north and south latitudes.
2
Erosional Work of Wind
- Wind has three-fold work: erosion, transportation, and deposition.
- Wind's erosive work is limited to heights close to the ground.
- Wind acts more strongly where loose particles are available.
3
Wind Erosional Landforms
- Deflation hollows are depressions formed by deflation.
- Oasis is formed when continuous deflation lowers the land surface until it reaches the water table.
- Permanent vegetation and human settlement can develop in an oasis.
4
Depositional Work of Wind
- When wind velocity decreases, it drops its load.
- Sand dunes and loess deposits are the main depositional landforms of wind.
- A sand dune is a mound, hill, or ridge of sand with a crest or definite summit.
