Desert

  1. 1. THE INDIAN DESERT
  2. 2. DESERTS A desert is a landscape or region that receives an extremely low amount of precipitation, less than enough to support growth of most plants.
  3. 3. DESERTS  Deserts are defined as areas with an average annual precipitation of less than 250 millimetres (10 in) per year.
  4. 4. DESERTS  Deserts are often composed of sand and rocky surfaces. Sand dunes called ergs and stony surfaces called hamada surfaces compose a minority of desert surfaces. Exposures of rocky terrain are typical, and reflect minimal soil development and sparseness of vegetation. The soil is rocky because of the low chemical weathering.
  5. 5. THE INDIAN DESERT  The Great Indian Desert (also known as the Thar Desert), is a large, arid region in the northwestern part of the Indian subcontinent.  With an area of more than 200,000 sq.km.  It is the world's 9th largest subtropical desert.
  6. 6. THE INDIAN DESERT  It lies mostly in the Indian state of Rajasthan, and extends into the southern portion of Haryana and Punjab states and into northern Gujarat state.
  7. 7. THE INDIAN DESERT  The Thar Desert is situated partly in India and partly in Pakistan. In India the thar desert extends from the Sutlej River in the north & northeast, surrounded by the Aravalli Range on the southeast, on the south by the salt marsh known as the Rann of Kutch (parts of which are sometimes included in the Thar), and on the west by the Indus river plains.
  8. 8. INDIAN DESERT  It is an undulating sandy plain covered with sand dunes.  Barchans (crescent shaped dunes) cover large areas.
  9. 9. INDIAN DESERT  It has arid climate with low vegetation cover.
  10. 10. INDIAN DESERT  Streams appear during the rainy season.  Rivers don't have enough water to reach the sea.  Inland Drainage.
