Antarctica is colder than the Arctic region, as much of Antarctica is over 3,000 m (9,800 ft) above sea level, where air temperatures are colder. The relative warmth of the Arctic Ocean is transferred through the Arctic sea ice and moderates temperatures in the Arctic region.
A map of the Antarctic region, including the Antarctic Convergence and the 60th parallel south The Antarctic Plate. The Antarctic (/ æ n ˈ t ɑːr t ɪ k / or / æ n ˈ t ɑːr k t ɪ k /, American English also / æ n t ˈ ɑːr t ɪ k / or / æ n t ˈ ɑːr k t ɪ k /; commonly / æ ˈ n ɑːr t ɪ k /) [Note 1] is a polar region around Earth's South Pole, opposite the Arctic region around ...
The Arctic has various definitions, including the region north of the Arctic Circle (currently Epoch 2010 at 66°33'44" N), or just the region north of 60° north latitude, or the region from the North Pole south to the timberline. [1] The Antarctic is usually defined simply as south of 60° south latitude, or the
Earth’s poles are undergoing simultaneous freakish extreme heat with parts of Antarctica more than 70 degrees (40 degrees Celsius) warmer than average and areas of the Arctic more than 50 ...
Most of the interior of Antarctica is polar desert, despite the thick ice cover. Conversely, the McMurdo Dry Valleys of Antarctica, although they have had no ice for thousands of years due to katabatic wind but contain ephemeral streams and hypersaline lakes characteristic of extreme non-polar deserts, are not necessarily polar desert ...
Antarctic waters predominantly sink beneath the warmer subantarctic waters, while associated zones of mixing and upwelling create a zone very high in marine productivity, especially for Antarctic krill. This line, like the arctic tree line, is a natural boundary rather than an artificial one, such as the borders of nations and time zones.
Like the United States, China has been expanding its presence in Antarctica and in the Arctic to explore polar resources. ... 25 hostess gifts from Walmart are way better than a bottle of wine. AOL.
A vital glacier in western Antarctica appears to be smoking in a rare view captured by a NASA satellite earlier this month. The so-called “sea smoke,” isn’t actually smoke, it’s fog ...
