What is the location of desert biome?

A desert is any dry terrestrial area on Earth. Desert covers about 1/5 of the Earth's land surface. That being said, it is also important to know that a desert can be hot OR cold, a common misconception being that they are always hot. Antarctica is the world's largest desert due to its very low rainfall and massive area. Hot deserts are all over the world, extending into the USA, South America, Africa, Europe, Australia, and Asia.

In many places, mostly in Australia and Asia.
