There are four prime kinds of desert found in the planet. These are:
1. Subtropical deserts: They are the hottest deserts. They are found in Africa, Asia, North America, and South America.
2. Coastal deserts: They occur in cool to warm regions along the coast like the Atacama Desert in Chile and Namib Desert in Africa.
