Desert Biome

By Phong and David

What is a desert biome

The desert biome is an ecosystem that forms due to the low level of rainfall it receives each year. There are four major types of desert in this biome - hot, dry, coastal and cold. Although the daytime temperatures of the desert biome are very hot.

About the desert biome

One-third of land on Earth is so dry and harsh that only specific plants and animals can survive there. The largest on Earth is the Sahara Desert in Africa and covers over 300 million square miles. This desert stretches over more than ten African countries for about 20%.

Location of deserts

Although most deserts such as sahara of North Africa and deserts of the Southwestern U.S. , Mexico, and Australia, occur at low latitudes another kind of deserts, cold deserts, occur in the range area of Utah and Nevada and in parts of Western Asia.

Hot at day cold at night

Because deserts are so dry and their humidity is so low they have no blanket to help insulate the ground. Many deserts can quickly get cold once the sun sets. Some deserts can reach to over 100 degrees .

Animals in Deserts

The animals that live in the desert usually have special adaptations that allow them to survive the extreme temperatures and conditions. A good example the camel. The camel can drink very large amounts of water. These are some of the animals in the desert.

Dry Desert climates are formed by high-pressure zones in which cold air descends. Then the descending air becomes warm but, instead of releasing rain, the heat from the ground evaporates the water before it can come down as rain. The ground is super hot because the sun's rays beat down on it directly overhead. Not a lot of atmosphere to protect it from radiant energy.

longitude and latitude

Many deserts are found in bands along 30 degrees latitude north and 30 degrees latitude south.


All months have average temperatures over 64° F (18° C) with an average annual temperatures over 64° F (18° C).
