Top 10 Antarctic factsAntarctic quiz
What sound can be heard when approaching an iceberg?
A fizz. When a piece of iceberg ice melts, it makes a fizzing sound called "Bergie Seltzer". This sound is made when the water-ice interface reaches compressed air bubbles trapped in the ice. As this happens, each bubble bursts, making a 'popping' sound. The bubbles contain air trapped in snow layers very early in the history of the ice, that eventually got buried to a given depth (up to several kilometers) and pressurized as it transformed into firn then to glacial ice.
This is Amundsen–Scott South Pole Station. Why is it elevated?
To avoid being buried in snow. All structures at the South Pole cause wind-blown snow to build up in the surrounding area (about four feet of snow per year). The station building has sloping lower portion of wall, which causes the snow to be scoured away.
After whom is Queen Maud Land in Antarctica named?
Norwegian queen. Queen Maud Land was the first part of Antarctica to be sighted. The name was initially applied in January 1930 to the land discovered by Hjalmar Riiser-Larsen and Finn Lützow-Holm during Norvegia expedition of 1929–30. It was named after the Norwegian Queen Maud of Wales, wife of the then-reigning King Haakon VII.
Which direction is not possible to point at when standing at the South Pole?
Neither east, west, nor south. At the South Pole every direction is north.
Where is Mount Vinson located?
In Antarctica. Mount Vinson is the highest peak in Antarctica, at 4,892 metres. It lies in the north part of Vinson Massif’s summit plateau in the south portion of the main ridge of the Sentinel Range about 2 kilometres north of Hollister Peak.
How much of the Earth's ice is in Antarctica?
About 90% of terrestrial ice is found in Antarctica.
Apart from the extreme cold, what is the other problem with the air in the Vostok Station in Antarctic?
All of the above. Vostok is one of the most difficult places on Earth for human habitation. It is extremely cold, there is no moisture in the air, it's always windy, the oxygen is low due to high altitude, the air is ionized and polar night lasts approximately 130 days.
Which known band played a concert in Antarctica?
Metallica is the first band to play on all seven continents . . . and they did it all in one calendar year. In 2013 they played in North America, South America, Europe, Asia, Africa, Australia and a special concert for some scientists in Antarctica.
Where is the saltiest lake in the world?
In Antarctica. With a salinity level of over 40%, Don Juan Pond is the saltiest of the Antarctic lakes. This salinity allows the pond to remain liquid even at temperatures as low as −50 °C (−58 °F) due to the interference of salts with the bonding of water molecules. Don Juan Pond was discovered in 1961 by George H. Meyer.
What is the lowest recorded air temperature ever recorded on Earth (Vostok Station - Antarctica)?
−89.2°C (−128.6°F). Vostok Station is a Russian research station in inland Princess Elizabeth Land, Antarctica. Founded by the Soviet Union in 1957, the station lies at the southern Pole of Cold, with the lowest reliably measured natural temperature on Earth of −89.2°C (−128.6°F; 184.0 K)
