Relevant history of Antarctica

Introduction to Antarctica:

Antarctica, the continent that surrounds Antarctica. Located at the southern tip of the earth, it is surrounded by the Pacific Ocean, the Indian Ocean and the Atlantic Ocean, and is bordered by the Belinsgau Ching, Ross, Amundsen and Weddell Seas. Antarctica is composed of continents, continental edge ice, and islands, with a total area of 10,000 square kilometers, of which the continental area is 10,000 square kilometers, the continental margin ice area is 10,000 square kilometers, and the island area is 10,000 square kilometers.

The whole territory is a large plateau with an average altitude of 2,350 meters, which is the highest average altitude in the world.

The continent is almost entirely covered by glaciers, accounting for more than 80% of the world's modern ice cover. Continental glaciers stretch from ** to the sea, forming a huge Ross ice barrier, and icebergs float in the surrounding sea.

Only 2% of the entire continent is free of snow and ice all year round, and plants and animals are able to survive. The climate is very cold, with extreme minimum temperatures reaching the year). Wind speeds generally reach 17 18 meters per second, and the maximum reaches more than 90 meters per second, making it the world's coldest land with the most storms and winds.

The average annual precipitation on the continent is 55 mm, there is almost no precipitation near the pole, and the air is very dry, which is called the "white desert".

In the Antarctic Circle, there are continuous polar days in the warm season and continuous polar nights in the cold season, and there are gorgeous arc-shaped aurora lights. Animals include penguins, walruses, sea lions, albatrosses, etc. Antarctic cod and largemouth fish are produced in the nearby oceans, and krill production is the largest in the world.

Minerals have been found in coal, oil, natural gas, gold, silver, nickel, molybdenum, manganese, iron, copper, uranium, etc., mainly distributed in the Antarctic Peninsula and coastal island areas.

Antarctica. It is the last continent that humans reached, also known as the "Seventh Continent." ”

Location: Located in the southernmost part of the earth, almost all of the land is within the Antarctic Circle, surrounded by the Pacific Ocean, the Indian Ocean and the Atlantic Ocean.

It is a continent with the highest geographical latitude in the world.

Area: The total area is about 14 million square kilometres, which is about the total land area of the world.

Range: It consists of continents, continental edge ice and islands around Antarctica, of which the continental area is 10,000 square kilometers, the continental edge ice area is 10,000 square kilometers, and the island area is 10,000 square kilometers.

Geographical Division: Antarctica is divided into two parts: East Antarctica and West Antarctica.

East Antarctica extends from 30°W to 170°E and includes Coates Land, Queen Maude Land, Leadby Land, Wilkes Land, George V Coast, Victoria Land, the Antarctic Plateau and the Pole.

It covers an area of 10.18 million square kilometres.

West Antarctica is located between 50°W and 160°W longitude, including the Antarctic Peninsula, Alexandria Island, Ellsworth Land, and Bird Land, covering an area of 2.29 million square kilometers.

Population: Antarctica has only a few scientific expeditions and whaling teams from other continents, and no settled inhabitants.
