West Antarctica was formed by the merging of several continental plates, which created a number of mountain ranges in the region, the most prominent being the Ellsworth Mountains. The presence of the West Antarctic Rift System has resulted in volcanism along the border between West and East Antarctica, as well as the creation of the ...
The lake contains both saline and fresh water layers. [8] [9] Algae Lake: An ice-free lake in the ice-free Bunger Hills highlands. Amphitheatre Lake: A surface lake. Beaver Lake: A surface lake, near a "stagnant" glacier, its name derives from the STOL Beaver aircraft used to supply a nearby base, not from the presence of actual beavers. Lake ...
A satellite image of the Sahara, the world's largest hot desert and third largest desert after Antarctica and the Arctic. Desert greening is the process of afforestation or revegetation of deserts for ecological restoration (biodiversity), sustainable farming and forestry, but also for reclamation of natural water systems and other ecological systems that support life.
Antarctica is the largest ice desert in the world. Some 98% of Antarctica is covered by the Antarctic ice sheet , the world's largest ice sheet and also its largest reservoir of fresh water . Averaging at least 1.6 km thick, the ice is so massive that it has depressed the continental bedrock in some areas more than 2.5 km below sea level ...
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,-k t ɪ k /, US also / æ n t ˈ ɑːr t ɪ k,-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 North Pole.
Parts of icy Antarctica are turning green with plant life as the region is gripped by extreme heat events, new research shows, sparking concerns about the changing landscape on this vast continent.
The Schirmacher Oasis (or Schirmacher Lake Plateau) [1] is a 25 km (16 mi) long and up to 3 km (1.9 mi) wide ice-free plateau with more than 100 freshwater lakes. It is situated in the Schirmacher Hills on the Princess Astrid Coast in Queen Maud Land in East Antarctica and is, on average, 100 m (330 ft) above sea level .
Antarctica experienced its warmest day ever recorded in February, with the mercury rising to 65 degrees Fahrenheit. The impact of climate change on the spread of snow algae is unclear, but it is ...
