  • The strongest winds in Antarctica can reach speeds of over 322 kmph (200 mph).
  • The average precipitation in Antarctica is around 160 mm. The continent is basically a cold desert.

3. About 98% of Antarctica is covered with ice, which has an average thickness of about 2 kilometers. Moreover, 90% of the world’s total ice is in Antarctica.

4. Antarctica has around 70 percent of Earth’s total freshwater.

5. Antarctica is the continent with the highest average elevation (about 2,500 meters). The highest mountain in Antarctica is Mount Vinson which has an elevation of 4,892 meters.

6. There is a huge amount of volcanic activity going on under the ice in Antarctica. 138 volcanoes have been discovered till now. Volcanoes under glacial ice are known as subglacial volcanoes or glaciovolcanoes.

7. The geographic South Pole is located in Antarctica.

8. In Antarctica, as we move toward the South Pole, the number of days when the sun is above the horizon during the winter decreases. At the South pole, there is no sunshine, not even twilight, during the winter.

On the contrary, there is continuous sunlight for the entire 24 hours of the day during summer at the South Pole.

9. There is no indigenous population living in Antarctica. However, there are always 1000-5000 people living in research centers. Emilio Marcos Palma was the first documented person to be born in Antarctica.

11. East Antarctica is colder than West Antarctica as it has a higher average elevation.

15. Many large chunks of icebergs have separated from Antarctica from time to time. For example, a 1,636 square-kilometer iceberg separated in 2019. An even bigger 2,240 square kilometer chunk separated in 2017.
