Desert

What are deserts?
1 Deserts cover about one fifth (20 percent) of the earth's land area. Some deserts get both very hot (during the day) and very cold (during the night, when temperatures can drop well below freezing). Some deserts, however, are always cold (for example, the Gobi Desert in Asia, and the desert on the continent of Antarctica) and are considered their own biome: the arctic tundra.

Where are deserts?

2 Most deserts are located on or near the Tropic of Cancer or Tropic of Capricorn (23.5ºN and S). The biggest desert is northern Africa's Sahara Desert; it covers roughly 3,500,000 square miles (9,065,000 square kilometers). The driest deserts are the Atacama desert of northern Chile, South America, and the Lut Desert in eastern Iran; these extreme deserts get less than half an inch (about 1 centimeter) of precipitation each year - and it is from condensed fog, and not from rain.

Rainfall (Precipitation)
3 The desert is a harsh environment with very little rainfall and extreme temperatures. All deserts get less than 10cm of precipitation a year.

Temperature
4 Temperatures during the day are very hot, sometimes over 120˚F and drop below freezing at night (below 32˚F, sometimes going into temperatures below 0).

Animals that Live in the Grasslands:

5 Different animals live in the different types of deserts. Animals that live in the desert have adaptations to cope with the lack of water, the extreme temperatures, and the shortage of food. To avoid daytime heat, many desert animals are nocturnal; they burrow beneath the surface or hide in the shade during the day, emerging at night to eat. Many desert animals do not have to drink at all; they get all the water they need from their food. Most desert animals are small.
