Topics in Aeolian Processes and Associated Landorms

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.
