Hot Deserts

• Hot Deserts are typically found at 30 degress north and south from the equator longitude.
• • Hot deserts are formed from Rain Shadows and prevailing winds.
  • Moist, hot air rises and condenses, causing rain on one side of a mountain, causing vegetation to grow there
  • The cool air sinks and is deprived of moisture and warms again, causing no vegetation as there is no humidity
• Desertification is caused by overgrazing (cattle), deforestation,(wood) and overcultivation(farm).
• Desertification is the process of fertile land turning into infertile land.
• Desert soils:

  • very dry, can get saturated easily
  • rocky, sandy, etc
• Deserts have less than 250mm of rainfall per year.
