The desert biome is an ecosystem that forms due to the low level of rainfall it receives each year.
They are found at the lower latitudes, between the Tropic of Cancer and the Tropic of Capricorn. Light winds
- Deserts cover about one fifth of the Earth's surface and occur where rainfall is less than 50 cm/year
- Light winds occur often which evaporates any type of moisture that is typically going to develop in them. The heat is very dry and that makes it hard for too many types of plants or animals to be able to survive in such biomes.
- It can be come cold as the sun goes down in the desert. This is because there are very few trees or other elements there to retain any heat
- Generally, a desert is defined as an area that receives less than 10 inches, or 25 centimeters, of precipitation a year.
- Deserts that receive rain as their main form of precipitation are referred to as 'hot' deserts, while deserts that receive snow as their main form of precipitation are 'cold' deserts.
