The Antarctica is actually a desert.
The Antarctica is all ice all the year. The warmest temperature ever recorded there is zero at the South Pole. Explorers(探险家) used to think that a place so cold would have a heavy snowfall. But less than ten inches of snowfalls each year. That is less than half an inch of water. Ten times that much moisture(水分) falls in parts of the Sahara.
The little snow that falls in Antarctica never melts(融化). It continues to pile up deeper and deeper year after year and century after century. When the snow gets to be about eighty feet deep, it is turned to ice by the weight of the snow above it.
