Antartica

Antarctica is Earth's southernmost continent, overlying the South Pole. It is situated in the southern hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. Antarctica has the lowest temperatures in our planet reaching 70° Celsius below zero with winds of 300 km. per hour. Containing 90% of the planet's ice it's the major reserve of fresh water on Earth. And has the highest average elevation of all the continents. About 99% of Antarctica is covered with ice at an average thickness of 2,500 meters, reaching in some places as deep as 4,776 meters. If the ice layer would melt all the Earth's Oceans would rise 70 meters above the actual level.
