Antarctica is the only land on our planet that is not owned by any country. Ninety percent of the world's ice covers Antarctica. This ice also represents seventy percent of all the fresh water in the world. As strange as it sounds, however, Antarctica is essentially a desert. The average yearly total precipitation is about two inches Although covered with ice (all but 0.4% of it, i.e.), Antarctica is the driest place on the planet, with an absolute humidity lower than the Gobi desert.
