Antarctica

When you think of deserts, what comes to mind? Chances are, you're thinking of sun, sand, and perhaps camels or cacti. The truth is, to technically qualify as a desert, an area only needs to receive less than 25 centimeters of precipitation per year. The majority of Antarctica is too cold to allow for precipitation in the form of rain or snow, so approximately 5.5 million square miles of Antartica is a desert. How’s that for a curveball? It’s even theorized that some parts of the Antarctic desert haven’t had any form of precipitation for two million years.
