Where are most of the large deserts?

Deserts are regions that receive very little rainfall, typically less than 250 millimeters (10 inches) per year. They are often characterized by sparse vegetation, high temperatures, and low humidity. Deserts can be found on all continents except Antarctica, but they are most common in the subtropical and tropical regions of the world.

Some of the largest deserts in the world include:

- The Sahara Desert in North Africa, which is the largest hot desert in the world, covering an area of over 9 million square kilometers (3.5 million square miles).

- The Arabian Desert in the Middle East, which is the second largest hot desert in the world, covering an area of over 2.5 million square kilometers (1 million square miles).

- The Gobi Desert in Central Asia, which is the largest cold desert in the world, covering an area of over 1.3 million square kilometers (500,000 square miles).

- The Atacama Desert in South America, which is the driest desert in the world, with some areas receiving less than 1 millimeter (0.04 inches) of rainfall per year.

- The Australian Outback, which is a large desert region in central and western Australia, covering an area of over 1.7 million square kilometers (660,000 square miles).
