Major Deserts of World

major deserts of world showing continents

 A desert is a barren area of land where little precipitation occurs and consequently living conditions are hostile for plant and animal life.  A place that receives less than 10 inches (25 centimeters) of rain per year is considered a desert. About one third of the land surface of the world is arid or semi-arid. Deserts cover more than one fifth of the Earth’s land, and they are found on every continent. Sahara, Kalahari and Arabian deserts are such examples of Major deserts of World. These areas exist under a moisture deficit, which means they can frequently lose more moisture through evaporation than they receive from annual precipitation.

And despite the misconceptions about major deserts of world that they are dry and hot, there are cold deserts as well. The largest hot desert in the world, northern Africa’s Sahara, reaches temperatures of up to 122 degrees Fahrenheit (50 degrees Celsius) during the day. But some of major deserts of world are always cold, like the Gobi desert in Asia and the desert of Antarctica. This includes much of the polar regions which are sometimes called “cold deserts”.

Deserts are classified in a number of ways, generally by total precipitation, number of days on which this falls, temperature and humidity. Deserts are sometimes also classified as hot or cold, semiarid or coastal.
