A desert is an area with very little rainfall or snow, which as a result becomes very dry, and any animals or plants that live in a desert have to develop special characteristics in order to survive with little water.
An oasis is an area within a desert where there is more vegetation and other life, usually because there is a spring or other natural water source. You can find more information about deserts here.
