The Largest Deserts on the Planet

The Main Deserts of the World

Deserts are arid regions characterized by very low precipitation and sparse vegetation. They cover about one-third of the Earth's surface and are found on all continents. Deserts are often associated with extremely high temperatures due to their low rainfall and direct exposure to the sun.

The hottest deserts are the Lut Desert (Iran) with 70.7°C in 2005, the Sahara Desert (North Africa) with 58°C in Aziziya, Libya, in 1922, and the Sonoran Desert (United States and Mexico) with 54.4°C in Death Valley, California, in 2013.
