The Antarctic(南极洲)is actually a desert.It is the only continent on the earth without a river or a lake.The Antarctic is all ice all year round.The warmest temperature ever recorded there is zero,at the South Pole.Explorers used to think that a place so cold would have a heavy snowfall.But less than ten inches of snow falls each yeat.That is less than half an inch of water.Ten times that much moisture falls in parts of the Sahara.The little snow that falls in Antarctic never melts.It continues to pile up deeper and deeper year after year.When the snow gets to be about eighty feet deep it is turned to ice by the weight of the snow above it.1.Antarctica is called a desert because it has little moisture and no lakes or rivers.A.TB.F2.The Antarctic has ten times as much moisture as the Sahara.A.TB.F3.The temperature in the Antarctic is always above zero.A.TB.F4.The snow In Antarctic is very deep because it piles up year after year.A.TB.F5.The snow turns to ice when the snow above it is heavy enough.A.TB.F
