Interesting Facts About the Desert

Deserts are locations that receive very little rainfall throughout the year.  Due to such conditions, animal and plant life is inhibited. About a third of the world’s land surface is either arid or semi-arid.  There are different types of deserts and they can be classified in terms of temperature, the amount of rainfall, the amount of humidity and a combination of other additional factors.

The main types of deserts are cold winter, polar deserts, cool coastal deserts and subtropical deserts. The polar deserts are the largest and are found in Antarctica. Hot deserts are the main types and they receive a little amount of rainfall throughout the year.  There are also cold deserts that have low moisture in most cases and the majority of those are found in central parts of Asia.

Desert Animals and Plants  

The daytime temperatures are very hot while night temperatures are very cold. Due to very hot day temperatures, the majority of the animals living in such areas have developed adaptations to survive in such locations. For example, the majority of the animals hibernate during the day and come out at night. They do this to adverse day conditions. The camel is one of the main desert animals and it stores body fat in its hump and can go for long periods of time without water.  On the other hand, the plants that grow in the desert tend to have long roots that search for water while some water is also stored in the stems.

Formation of Deserts

The majority of deserts are formed through hardening of crystalline rocks over a long period of time leading to the formation of sand. Other deserts were formed through tectonic movements that have made them evolve into the Rocky Mountains of crumpled land areas.
