The largest desert in the world is the Antarctic Desert, which covers an area of about 14 million square kilometers.
Despite being cold, Antarctica is classified as a desert because it receives very little precipitation, averaging less than 50 millimeters per year.
While most people associate deserts with hot climates, deserts are defined by their dryness, not temperature.
The Sahara Desert is the largest hot desert in the world, but it is not the largest overall. The Gobi and Kalahari are also significant deserts but are smaller than the Antarctic Desert.
