MAJOR DESERTS OF THE WORLD UPSC

A desert is a landscape or region that receives very little precipitation - less than 250 mm per year (about ten inches).
Approximately 1/3 of Earth's land surface is a desert.
There are four different types of deserts based upon their geographic situation:
- polar deserts,
- subtropical deserts,
- cold winter deserts, and
- cool coastal deserts.
