Antarctica is the fifth largest continent in the world, and the most southern, located almost entirely within the Antarctic Circle. It is the only continent on Earth that is completely surrounded by ocean. Antarctica is covered by an ice sheet that averages 1.6 kilometers (1 mile) in thickness and is the highest, driest, coldest, windiest, and most inhospitable continent on the Earth. The total area of Antarctica is estimated at 14 million square kilometres (5.4 million square miles), including its islands and the waters it contains. Its land mass is roughly twice the size of Australia, making it the fifth largest continent. Antarctica is also the most remote and isolated continent on the planet, being almost 7,000 kilometres (4,300 miles) from the nearest landmass. The majority of Antarctica is covered by the Antarctic ice sheet, which is estimated to contain about 90 percent of the world's fresh water. The average thickness of the ice sheet is 1.6 kilometres (1 mile), with the highest point being 4,776 metres (15,694 ft) above sea level at Vinson Massif. The ice sheet covers an area of 14 million square kilometres (5.4 million square miles). The continent is largely uninhabited, with only a few thousand research personnel living there during the summer months. Most of the continent is classified as a desert, with average temperatures ranging from -20°C (-4°F) to -80°C (-112°F). The climate of the continent is extremely harsh, and the winds can reach speeds of up to 320 kilometres per hour (200 mph). In addition to the ice sheet, Antarctica is also home to numerous glaciers, mountains, valleys, and rivers. The Antarctic Peninsula is the most biologically active region of the continent, with a wide variety of cold-adapted plants, birds, and mammals.
