A desert is an arid region characterized by extremely high or low temperatures and has scarce vegetation. People have learned to cope with extreme harsh temperatures; in some places as hot as fire and some as cold as ice. These are characterized by low rainfall, scanty vegetation and extreme temperatures. Depending on the temperatures there can be hot deserts or cold deserts. The people inhabit these lands wherever little water is available to practice agriculture.
