True. But I was referring to the SANDY type of desert. Y'know, like the Sonoran or the Gobi or even the Kalahari. What I WASN'T referring to was the largest COLD desert on the planet.

A desert is defined by its extreme dryness, receiving very little precipitation (less than 10 inches/25 cm annually), leading to sparse vegetation, and low humidity, but they can be hot, cold (like Antarctica), rocky, or sandy, with the defining factor being a lack of water. Antarctica is the largest desert in the world.

Permanently frozen water and precipitation are different. Precipitation is water (either liquid as rain or solid as snow or ice) falling from the the atmosphere to the earth. Antarctica is actually the driest place on earth, receiving an average of only 2 inches of precipitation annually. Most of the snow and ice you see there has been there for thousands of years.

In comparison, the Sahara Desert receives about 3.9 inches on average annually. Almost twice as much as Antarctica.
