The continent Antarctica is the most southern area of land on the Earth and is mostly covered with ice.People have never wanted to l 67 there because of its coldest temperature.But now scientists from all over the w 68 come to study the ice to learn more about the Earth’s history.Some scientists live on Antarctica for part of the y 69 .But they don’t usually stay there for more than six months b 70 there are six months of light and six months of darkness.
Antarctica usually has a good deal of f 71 weather without any wind at all.The strong winds are usually only in some parts of it.It is also i 72 to learn that it isn’t very wet there.There is very l 73 snow or rain.It snows on the ice in winter,but at other times Antarctica is d 74 ,just like the Sahara Desert.
In winter the sea around Antarctica freezes for t 75 of kilometers.But scientists tell us that the earth is getting w 76 .So in the future,there may be less ice in the Antarctic sea.When that happens,our weather will never be the same again.
