The wildlife of Antarctica are extremophiles, having adapted to the dryness, low temperatures, and high exposure common in Antarctica. The extreme weather of the interior contrasts to the relatively mild conditions on the Antarctic Peninsula and the subantarctic islands , which have warmer temperatures and more liquid water.
Nearly all of Antarctica is covered by a sheet of ice that is, on average, at least 1,500 m (5,000 ft) thick. Antarctica contains 90% of the world's ice and more than 70% of its fresh water. If all the land-ice covering Antarctica were to melt — around 30 × 10 ^ 6 km 3 (7.2 × 10 ^ 6 cu mi) of ice — the seas would rise by over 60 m (200 ft ...
The temperatures in the Arctic are different depending on the location. Temperatures in the Arctic have a higher range than in the Antarctic. Temperatures can range as much as 100 °C (180 °F). Along the coast in the Arctic temperatures average −30 to −40 °C (−22 to −40 °F) in December, January and February. [7]
Antarctica's two flowering plant species, the Antarctic hair grass (Deschampsia antarctica) and Antarctic pearlwort (Colobanthus quitensis) are found on the northern and western parts of the Antarctic Peninsula, including offshore islands, where the climate is relatively mild. Lagotellerie Island in Marguerite Bay is an example of this habitat.
Polar bear in Manitoba, Canada.November 2004. Polar seas is a collective term for the Arctic Ocean (about 4-5 percent of Earth's oceans) and the southern part of the Southern Ocean (south of Antarctic Convergence, about 10 percent of Earth's oceans).
The U.S.-based team used a sterile hot water drill to reach and collect samples from Lake Whillans, one of Antarctica's roughly 400 lakes, which are kept liquid by pressure, friction and the ...
The water temperature fluctuates at −1.3–3 °C (29.7–37.4 °F). The waters of the Southern Ocean form a system of currents. Whenever there is a West Wind Drift, the surface strata travels around Antarctica in an easterly direction.
At around 600 miles wide and up to 6,000 meters (nearly four miles) deep, the Drake is objectively a vast body of water. To us, that is. To the planet as a whole, less so.
