One-tenth of the Earth's surface is always under the cover of ice. And almost 90 per cent of that ice is to be found in the continent of Antarctica. The remaining 10 per cent is found on the mountains in the form of glaciers. The ice sheet that covers Antarctica is almost one-and-a-half times the size of America. The only creatures that live on Antarctica throughout the year are insects.

Antarctica also has one active volcano. It is called Mt. Erebus and it emits steam and gives out ash even though it is in a snowy region
