A region is arid when it is characterized by a severe lack of available water, to the extent of hindering or preventing the growth and development of plant and animal life. Environments subject to arid climates tend to lack vegetation and are called xeric or desertic.
Desert: a region with so little vegetation that no significant population can be supported on that land. This implies that it is dry, but not necessarily hot. There are several kinds of deserts, but they all have one thing in common - they each receive less than 25 cm (~10) of precipitation per year. Polar ice and snow deserts - the cold climate produces both low precipitation and relatively high evaporation rates, e.g., Antarctica.
