The location of deserts is dependent on two factors, latitude and global wind patterns. Most deserts are located between 15' and 35' latitude, both north and south of the equator. In terms of global wind patterns, most deserts are located within the Southeastern and Northeastern trade winds belt.
Most of the world's deserts occur at low latitudes close to the equator, although there are high-latitude deserts as well. Both hot and cold deserts exist, and deserts occur on all seven continents. Approximately one-fifth of the Earth is desert. Desert classifications include hot and dry, semiarid, coastal and cold. While most conceive of deserts as hot environments, a desert is any region of the world that receives less than 50 centimeters of rainfall every year. Hot and dry deserts occur in North America, South America, Asia, Africa and Australia. Examples of this desert type are the Mojave Desert in North American and Africa's Sahara Desert.
