What is a Desert?


Deserts, generally are defined as areas which receive less than 250 mm (10 in) of precipitation each year. A region of land that is very dry because it receives low amounts of precipitation in the form of rain, maybe snow, mist or fog.

Deserts can be the hottest and most inhospitable places on Earth like Sahara and Gobi deserts. At the same time, they can also be cold and chilly with little to no snowfall like in the Antarctic and Arctic.

Types of Deserts

Deserts make up one-third of the surface of the Earth. There are four fundamental types of deserts. Hot and Dry Deserts, Cold Winter Deserts, Coastal Deserts and Polar Deserts.

  • Hot and Dry Deserts experience very little rainfall, hot temperatures during the day and freezing temperatures during the night. They are characterized by sand, rocks, gravel, and a few sparse oases. The Sahara Desert is the largest hot desert in the world.
  • Cold Winter Deserts experience dry summers and winters with brief intervals of rainfall. They are similar to the hot desert but somewhat cooler.
  • Coastal Deserts have cool winters but long warm summers. During the winters temperature averages, 6°C but can drop to -4 or -5°C. During the summers temperature ranges between 13 and 24° Celsius. The annual average rainfall is between 3 and 6 inches.
  • Polar Deserts Polar deserts are cold deserts. They are located at the earth’s poles. They receive annual precipitation of between 6 and 10 inches. The Antarctic is the world largest desert. The Arctic is the second largest desert extending across Alaska, Canada, Iceland, Greenland, Sweden, Norway, Russia, and Finland.
