The need to find food and water has led many desert civilizations to become nomadic. Please be respectful of copyright. As a result, wind and water erode the nutrient-rich topsoil. As the air rises, it cools and drops its moisture as heavy tropical rains. The global and regional climate can be altered by an increase in carbon storage, as well as changes in land surface albedo (LSA) and evaporation. Deserts may seem lifeless, but in fact many species have evolved special ways to survive in the harsh environments. This leaves what we call 'habitable land'. Daytime temperatures in the Chihuahua can climb beyond 37C (100F), while nighttime temperatures can dip below freezing (0C or 32F). All of this contributes to soil erosion and an inability for the land to retain water or regrow plants. The driest deserts, such as Chile's Atacama Desert, have parts that receive less than .08 inches (2 mm) of precipitation a year. These areas exist under a moisture deficit, which means they can frequently lose more moisture through evaporation than they receive from annual precipitation.

How are our forests distributed across the world regions? Are these boots made from endangered elephants? Large areas of desert soil are irrigated by water pumped from underground sources or brought by canal from distant rivers or lakes. The descending air hinders the formation of clouds, so very little rain falls on the land below.The worlds largest hot desert, the Sahara, is a subtropical desert in northern Africa.
