Overview
Antarctica is Earth's southernmost and least-populated continent, lying almost entirely south of the Antarctic Circle and encircled by the Southern Ocean. It is home to the geographic South Pole, making it one of the most remote and extreme environments on the planet.
Size and Geography
Antarctica is the fifth-largest continent in the world, with a total area of approximately 14,200,000 square kilometers (5,500,000 square miles). To put this into perspective, the continent is about 40% larger than Europe, despite having virtually no permanent human population.
The Antarctic Ice Sheet
The defining feature of Antarctica is its massive ice sheet, which covers the vast majority of the continent's landmass. This ice sheet has an average thickness of about 1.9 kilometers (1.2 miles), making it one of the largest reservoirs of freshwater on Earth. The sheer scale of the ice has shaped both the continent's landscape and its role in global climate systems.
