Desert is defined as a location with fewer than 10 inches (25 centimetres) of annual rainfall. Deserts cover approximately a fifth of the Earth’s land surface and can be found on all continents. Semi Arid, Hot and Dry, Cold, and Coastal deserts are the four basic types of deserts that can be found.

In other words a desert can be defined as a land that is completely devoid of life. Almost all deserts are found between 15-30 degrees latitude north-south.

Different Types of Deserts:

  1. Hot and Dry Deserts: They are the hottest among all deserts. These are also known as arid or subtropical deserts. Year around, the temperature in these deserts is warm and dry.
  2. Semi-Arid Deserts: These are similar to hot and dry deserts, but the temperature in comparison to them is cooler.
  3. Coastal Deserts: These kinds of deserts are found near large water bodies. They are humid in comparison to the other kind of deserts. The Atacama Desert in South America is a coastal desert.
  4. Cold Deserts: These deserts are having extremely cold temperatures and dry conditions. Basically found in polar areas.
