Most people envision a desert as a sand-covered, hot, and dry region. However, there are also additional desert types. Any sizable area that receives relatively little rain annually is considered a desert. Desert regions support very few plant or animal species. There are several different definitions to describe a desert, but they are typically areas that receive extremely low amounts of rain. In a year, deserts generally receive less than 16in of rain. Deserts can be hot or freezing cold. In scorching deserts, summertime midday temperatures are frequently exceeding 100 °F (38 °C). Artic and Antarctic have cold deserts.
Features of Deserts
Deserts cover twenty percent of the territory on Earth. They are found on every continent. The land features of deserts vary widely. They could consist of mountains, bare rock, rocky plains, and moving dunes. Contrary to popular belief, dunes are not as common in deserts. For instance, they only account for 10% of the Sahara in northern Africa. Some deserts don't even have sand.

The tropics are home to the majority of hot deserts. On either side of the equator is this strip of Earth.
Farther from the equator than hot deserts are cold deserts. Despite being extremely dry, the fact that it is so cold there is the main cause of the lack of plants there. Much of Antarctica is covered by a chilly dessert. An additional chilly desert is the Gobi in central Asia.
