·      Antarctica is Earth’s southernmost continent, underlying the South Pole

·      It is situated in the Antarctica region of the southern hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean

·      It is the fifth-largest continent in area after Asia, Africa, North America and South America

·      About 98% of Antarctica is covered by ice

·      Antarctica is the highest, driest, windiest, coldest continent in the world

·      Antarctica is the highest continent on earth. Average elevation is 2500m

·      Antarctica is the driest continent on earth with an absolute humidity lower than that of the Sahara Desert

·      Winds in Antarctica are mostly caused by heavy cold air located over the Antarctic plateau falling under gravity towards the sea. As the air falls it gathers speeds and reaches speeds of over 300 knots at the coast

·      Antarctica is buried under a vast ice cap upto 4km thick in places. The weight of this ice cap is so vast that much of the ground below is pressed down below sea level

·      Only cold-adapted plants and animals survive there, including penguins, seals, mosses, lichen, and many types of algae
