Approximately one-third of the Earth’s land surface is classified as desert. Deserts are regions that receive very little precipitation, typically less than 250 millimeters (10 inches) of rain per year. These regions are characterized by extreme temperatures, sparse vegetation, and a variety of unique geological features.
Deserts are found in many parts of the world, including the Sahara in Africa, the Arabian Desert in the Middle East, the Mojave and Sonoran Deserts in North America, and the Gobi Desert in Asia. While deserts can be inhospitable places for many forms of life, they are home to a variety of specialized plants and animals that have adapted to survive in these harsh conditions.
