Western Antarctica and Eastern Antarctica correspond roughly to the eastern and western hemispheres relative to the Greenwich meridian. This usage has been regarded as Eurocentric by some, and the alternative terms Lesser Antarctica and Greater Antarctica respectively are sometimes preferred. There has been some concern about this ice sheetbecause there is a small chance that it will collapse.
Stand at the South Pole and you will be on solid ground — well, solid ice over metres thick. The Geography of Antarctica Ice formation in the Arctic.
The differences between the Arctic and the Antarctic are stark. The Arctic is a large ocean surrounded by land.
Antarctica is a large continent surrounded by an even larger ocean. Antarctica is a roughly circular continent with a long finger of land reaching out to South America as if trying to stay connected to the rest of Gondawana as it drifted away. Two major indentations in the coast are ice-infested seas, studded with icebergs encased in frozen sea.
At the head of these bays are ice shelves and the glaciers that feed them, leading into the heart of a vast frozen land. Antarctica and its altitude Antarctica and its altitude. Both the poles are cold.
But what makes Antarctica much colder than the Arctic is that most of the Antarctic continent is not at sea level but at high altitude.
The average altitude of Antarctica is metres the highest elevation of all continents and over twice the average elevation of Asia, the next highest.
It has over 26 million cubic kilometres of pure fresh water, frozen solid, and is metres through at its thickest point.
Antarctic geography The Prince Charles Mountains, inland of Mawson, contain some of the highest peaks in the Australian Antarctic Territory. (Photo: David Neilson). A key stage 3 Geography revision resource on Antarctica. Sub-topics include: Climate, Ecosystems in Antarctica, Potential resources, Tourism, and Climate change. Over 98% of Antarctica is covered by ice. It is the driest and coldest continent on earth. Antarctica is the fifth largest continent based on size, but it is the smallest in population with an official population of 0 (although some people do visit for scientific research).
That is enough to raise global oceans 58 metres if all of it were to melt. In fact, there is so much ice that in some parts of Antarctica the weight of ice depresses the underlying land below sea level.
The Geography of Antarctica Stand at the North Pole and, if you are lucky, you will be standing on a layer of ice. If you are still lucky it may be 2 metres thick, otherwise, you’ll be treading water 4 kilometres deep. Greater Antarctica and Lesser Antarctica are divided by the Transantarctic Mountains. However, the highest point in Antarctica is located in the Ellsworth Mountains, part of West Antarctica. The Antarctic Treaty () prevents militarization of the Antarctic continent and suspends territorial claims by states for the life of the treaty.
The highest point of the Antarctic ice sheet is a place called Dome A. The ice has formed from the slow accumulation of snow over thousands of years.
Imagine a snow flake landing at Dome A. It settles into the surface and then more snow falls to cover it. The gradual snow load compresses the flakes into a mass of ice. Then the relentless force of gravity starts the ice moving.
From Dome A it is all downhill to the coast. The ice slowly builds momentum as it follows flow lines in the underlying bedrock and the weight of accumulating snow pushes from behind.
The glaciers, essentially rivers of ice, take form guided by the sub-glacial mountains and valleys, eventually to reach the coast many thousands of years later. Glaciers and Icebergs A glacier in Antarctica.Kids learn about the geography of Antarctica.
Maps, natural resouces, and facts about this continent. Over 98% of Antarctica is covered by ice. It is the driest and coldest continent on earth. Antarctica is the fifth largest continent based on size, but it is the smallest in population with an official population of 0 (although some people do visit for scientific research).
Cultural Geography A Culture of Science While the Antarctic does not have permanent residents, the region is a busy outpost for a variety of research scientists.
These scientists work at government-supported research stations and come from dozens of different countries. The number of scientists conducting research varies throughout the year, from about 1, in winter to around 5, in summer.
