Dominik [7]

Of the total Earth's surface, approximately 20 percent is covered with deserts. The majority of the desert takes place in the area band situated along the 30 degrees latitude in North and 30 degrees latitude in the south. Even some of the deserts are also situated in the regions of mountains.  

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.  

3. Cold winter deserts: They are also known as semi-arid deserts. The Great Basin, the Colorado Plateau, and the Red desert are all cold winter deserts.  

4. Polar deserts: They are found in the Antarctic and Arctic regions.
