The deserts in the world are divided into three types.
- Subtropical deserts - they are the hottest deserts with dry terrain and rapid evaporation rate.
- Cool coastal deserts - the average temperature in these deserts is much cooler because of cold offshore oceanic currents.
- Cold winter deserts - they are striking with harsh temperature differences ranging from 38°C in summers to -12°C in winters.
