Desert A desert is a region of land that is very dry because it receives low amounts of precipitation (usually in the form of rain but may be snow, mist or fog), often has little coverage by plants, and in which streams dry up unless they are supplied by water from outside the area.n English before the 20th century, desert was often used in the sense of unpopulated area, without specific reference to aridity; but today the word is most often used in its climate-science sense (an area of low precipitation).

Definitions &Translations Drought. Drought is an extended period of months or years when a region notes a deficiency in its water supply whether surface or underground water.
