Deserts are arid regions, generally receiving less than ten inches of precipitation a year, or regions where the potential evaporation rate is twice as great as the precipitation.
The world’s deserts are divided into four categories. Subtropical deserts which are the hottest, with parched terrain and rapid evaporation. Although cool coastal deserts are located within the same latitudes as subtropical deserts, the average temperature is much cooler because of frigid offshore ocean currents. Cold winter deserts are marked by stark temperature differences from season to season, ranging from 100 F (38 C) in the summer to 10 F (12 C) in the winter. Polar Regions are also considered to be deserts because nearly all moisture in these areas is locked up in the form of ice.
