"Antarctica is twice the size of Australia"
The southernmost continent, south of the Southern Ocean, containing the South Pole.
The wider South Polar region comprising the Antarctic Continent as well as the adjacent Antarctic and Subantarctic islands, and the Southern Ocean waters situated south of the Antarctic Convergence.

Antarctica is Earth's southernmost continent, containing the geographic South Pole. It is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. At 14.0 million km², it is the fifth-largest continent in area after Asia, Africa, North America, and South America. For comparison, Antarctica is nearly twice the size of Australia. About 98% of Antarctica is covered by ice that averages at least 1 mile in thickness. Antarctica, on average, is the coldest, driest, and windiest continent, and has the highest average elevation of all the continents. Antarctica is considered a desert, with annual precipitation of only 200 mm along the coast and far less inland. The temperature in Antarctica has reached −89 °C. There are no permanent human residents, but anywhere from 1,000 to 5,000 people reside throughout the year at the research stations scattered across the continent. Only cold-adapted organisms survive there, including many types of algae, animals, bacteria, fungi, plants, and protista. Vegetation where it occurs is tundra.
The continent containing the South Pole with an extensive thick layer of ice covering most of the continent, with a variety of vegetation, animals, marine life and plant life, a cold climate and a moderate amount of snowfall.
Antarctica is the coldest of Earth's continents. The coldest natural temperature ever recorded on Earth was −89.2 °C (−128.6 °F) at the Soviet (now Russian) Vostok Station in Antarctica on 21 July 1983.

Sample Sentences & Example Usage
Our main disagreement is for East Antarctica and the interior of West Antarctica – there, we see an ice gain that exceeds the losses in the other areas.
The seas of Antarctica are treacherous and unforgiving, this incident is a sobering reminder of the importance of the U.S. icebreaker fleet as we see increased human activity in the polar regions.
Antarctica is shedding 160 billion tons of ice annually and that figure is rising, it's heartbreaking for those of us who've been fortunate enough to witness the place in all its chilling beauty. Forget Cuba. If there's one destination you need to see now, it's Antarctica.
If the losses of the Antarctic Peninsula and parts of West Antarctica continue to increase at the same rate they’ve been increasing for the last two decades, the losses will catch up with the long-term gain in East Antarctica in 20 or 30 years - I don’t think there will be enough snowfall increase to offset these losses.
The good news is that Antarctica is not currently contributing to sea level rise, but is taking 0.23 millimeters per year away, but this is also bad news. If the 0.27 millimeters per year of sea level rise attributed to Antarctica in the IPCC report is not really coming from Antarctica, there must be some other contribution to sea level rise that is not accounted for.
