అంటార్కిటికా అనేక ప్రశ్నలతో నిండిన ఖండం | Mysteries of Antarctica Antarctica (/ænˈtɑːrktɪkə/ ⓘ)[note 1] is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean (also known as the Antarctic Ocean), it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of 14,200,000 km2 (5,500,000 sq mi). Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of 1.9 km (1.2 mi). Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over 200 mm (8 in) along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost 60 metres (200 ft). Antarctica holds the record for the lowest measured temperature on Earth, −89.2 °C (−128.6 °F). The coastal regions can reach temperatures over 10 °C (50 °F) in the summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation occurs, it is mostly in the form of lichen or moss. The ice shelves of Antarctica were probably first seen in 1820, during a Russian expedition led by Fabian Gottlieb von Bellingshausen and Mikhail Lazarev. The decades that followed saw further exploration by French, American, and British expeditions. The first confirmed landing was by a Norwegian team in 1895. In the early 20th century, there were a few expeditions into the interior of the continent. British explorers, Robert Falcon Scott and Ernest Shackleton, were the first to reach the magnetic South Pole in 1909, and the geographic South Pole was first reached in 1911 by Norwegian explorer, Roald Amundsen.[4] Antarctica is governed by about 30 countries, all of which are parties of the 1959 Antarctic Treaty System. According to the terms of the treaty, military activity, mining, nuclear explosions, and nuclear waste disposal are all prohibited in Antarctica. Tourism, fishing and research are the main human activities in and around Antarctica. During the summer months, about 5,000 people reside at research stations, a figure that drops to around 1,000 in the winter. Despite the continent's remoteness, human activity has a significant effect on it via pollution, ozone depletion, and climate change. The melting of the potentially unstable West Antarctic ice sheet causes the most uncertainty in century-scale projections of sea level rise, and the same melting also affects the Southern Ocean overturning circulation, which can eventually lead to significant impacts on the Southern Hemisphere climate and Southern Ocean productivity. amazing facts in telugu, interesting facts in telugu, unknown facts, interesting and amazing facts, most interesting facts, telugu unknown facts, facts, interesting facts, interesting facts you never know, most amazing top 10, interesting facts, telugu facts, telugu interesting facts, telugu real facts, amazing, arun surya teja, t talks,think deep,think deep videos,think deep riddles,think deep riddles in telugu,think deep new video #interestingfacts# antarctica# antarctica secrets# antarctica theories# secrets antarctica# antarctica documentary# antarctic# antarctica facts# secret meetings# #telugu wonders #think_deep_latest_videos​​​​​​​​​​ ​ concept and Editing :- V . jagannadham scropting &Voice Over :- *V . jagannadham Disclaimer- Some contents are used for educational purpose under fair use.
