1. Antarctica

   Antarctica (UK: or, US: (listen)) is Earth's southernmost continent. It contains the geographic South Pole and 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 14,200,000 square kilometres (5,500,000 square miles), it is the fifth-largest continent and nearly twice the size of Australia. At 0.00008 people per square kilometre, it is by far the least densely populated continent. About 98% of Antarctica is covered by ice that averages 1.9 km (1.2 mi; 6,200 ft) in thickness, which extends to all but the northernmost reaches of the Antarctic Peninsula. Antarctica, on average, is the coldest, driest, and windiest continent, and has the highest average elevation of all the continents. Most of Antarctica is a polar desert, with annual precipitation of 20 cm (7.9 in) along the coast and far less inland. The temperature in Antarctica has reached −89.2 °C (−128.6 °F) (or even −94.7 °C (−135.8 °F) as measured from space), though the average for the third quarter (the coldest part of the year) is −63 °C (−81 °F). Anywhere from 1,000 to 5,000 people reside throughout the year at research stations scattered across the continent. Organisms native to Antarctica include many types of algae, bacteria, fungi, plants, protista, and certain animals, such as mites, nematodes, penguins, seals and tardigrades. Vegetation, where it occurs, is tundra. Antarctica is noted as the last region on Earth in recorded history to be discovered, unseen until 1820 when the Russian expedition of Fabian Gottlieb von Bellingshausen and Mikhail Lazarev on Vostok and Mirny sighted the Fimbul ice shelf. The continent, however, remained largely neglected for the rest of the 19th century because of its hostile environment, lack of easily accessible resources, and isolation. In 1895, the first confirmed landing was conducted by a team of Norwegians. Antarctica is a de facto condominium, governed by parties to the Antarctic Treaty System that have consulting status. Twelve countries signed the Antarctic Treaty in 1959, and thirty-eight have signed it since then. The treaty prohibits military activities and mineral mining, prohibits nuclear explosions and nuclear waste disposal, supports scientific research, and protects the continent's ecozone. Ongoing experiments are conducted by more than 4,000 scientists from many nations.

1. Antarctica

   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.

Examples of Antarctica in a Sentence

1. Maria Valdes:

   I’m eager to go back there, for sure, based on the satellite study, there are 300,000 meteorites, at least, waiting to still be collected in Antarctica. And the larger the (number of) samples that we have, the better we can understand our solar system.

2. Thomas Duconseille:

   At the end of summer, we are happy to come home, but it’s a mixed feeling: we’re sad to leave Antarctica, it’s an incredible environment and a unique life that we have here.

3. Catherine Bradshaw:

   With the big ice sheet on Antarctica like we have today, the predominant winds are known as katabatic winds, and these go from the land to the sea, they originate from the ice sheet where it is very high, very cold and very dry -- in fact Antarctica receives only a few inches of snowfall a year and is so dry it is classified as a desert.

4. Gavin Schmidt:

   We will see instances of extreme precipitation that will break records or see extreme heat waves that will break records. We will see increased wildfires ; we will see increases in coastal flooding ; we will see increases in sea level ; we will see increased mass loss from Greenland and Antarctica, these are very predictable aspects of the climate.

5. Thomas Duconseille:

   I have always been drawn to atypical landscapes, beautiful areas, places at altitude. It’s a small world – the world of people who do this work in these regions – so another cook told the station’s director about me. Working at one place can open new doors, and that’s how I got from the Alps to Antarctica.
