Antarctica

No, Alaska is not close to Antarctica. Alaska is located in the northern hemisphere, while Antarctica is located in the southern hemisphere. The two regions are separated by thousands of miles and several other countries.

The ozone hole over Antarctica disappears for about a half-year, every year. Another one forms over the North pole. Ozone holes form over the pole where there is no UV-C to form new ozone, because ozone is unstable and decays, and because contaminants can help ozone decay with even very low energy light.

Approximately 90% of an ice sheet is underwater, with only about 10% visible above the water's surface. This underwater ice helps stabilize the ice sheet by providing structural support and preventing it from sliding into the ocean.

• The most extreme cold on the planet.
• A very thick ice sheet.
• Isolation from any town, city or industrial development.
• Having to cross the roughest seas on the planet to get any cargo back to the industrialized world.
• Gigantic icebergs like multi-million tonne ploughs that threaten shipping, platforms and pipelines.
• The annual "icing-in" of the continent when the area around the coasts freeze so that only the most powerful (and expensive) ice breakers can get through.

  Antarctica is occupied by a succession of visitors, measured in thousands in the summer and hundreds occupying the various scientific bases in the winter.

The peninsula to the south of Tierra del Fuego is part of Antarctica. Specifically, it is called "Graham Land".

Antarctica is largely free of avalanches due to its low snowfall and lack of steep slopes. However, some areas where glaciers meet the sea, such as the Antarctic Peninsula, may experience some avalanches.

Continental glaciers cover Antarctica and most of Greenland because these are the coldest places on Earth, with temperatures that allow snow to accumulate and not melt. Over time, the accumulation of snow compacts into ice, forming massive ice sheets that spread across the land.

Antarctica is larger than the North Pole. Antarctica is a continent that covers an area of approximately 5.5 million square miles, while the North Pole is simply a geographic point located in the Arctic Ocean.

The Beardmore Glacier is important because it provides access to the interior of Antarctica, allowing for scientific research and exploration of the continent. It is also notable for its historical significance as part of the route used by Roald Amundsen during his successful journey to the South Pole in 1911. Additionally, the glacier serves as a key route for traversing the Transantarctic Mountains.

Antarctica is the continent around the South Pole. It is the southernmost continent and is covered by ice, making it the coldest and driest continent on Earth.

No, the Antarctic is considered a separate continent.

Yes, at least one: Mt Erebus.

The ozone hole forms over Antarctica in winter due to a combination of factors, including extreme cold temperatures and the presence of polar stratospheric clouds. These clouds promote chemical reactions that break down ozone molecules. Additionally, the lack of sunlight during the winter months allows these reactions to occur without interference from sunlight.

An atmospheric scientist studying the atmosphere in Antarctica is probably known as the P I or Principal Investigator, to whom monies have been granted by a government to answer a particular scientific question.

The North Pole is near the Arctic region, which is located in the northern part of the Earth near the North Pole. Antarctica is at the opposite end of the Earth, in the southern hemisphere. Europe is a continent located between Asia and the Atlantic Ocean.

The Prime Meridian crosses Antarctica in the same place that it crosses any geography that it touches: at zero degrees E/W, which turns into 180 degrees E/W-- the International Date Line -- at the South Pole, which is 90 degrees South Latitude.

Other countries took action to fix the ozone hole in Antarctica by signing the Montreal Protocol in 1987, which aimed to phase out the production of ozone-depleting substances. This treaty successfully led to a decrease in the use of these harmful chemicals, resulting in a gradual recovery of the ozone layer over time.

Open water surrounded by ice is called a polynya. Polynyas are areas of unfrozen seawater that stay open even when the surrounding water is frozen solid with ice. They are important habitats for marine life and can have a significant impact on regional ocean and atmospheric conditions.

Antarctica is a continent -- 10% of the earth's surface -- and will not melt. It's ice sheet, however, is subject to melting, and, it covers 98% of the continent.

There is no way to determine how long it would take for all the ice to melt off the continent.

The coast of Antarctica that is closest to the South Pole is the coast of the Ross Sea, which is located in the Pacific Ocean. It is approximately 700 kilometers (435 miles) from the Ross Sea coast to the South Pole.

Yes. There are two flowering plants, Antarctic hair grass and Antarctic pearlwort. Very little vegetation grows on Antarctica, mostly mosses and liverworts, and these exist on the warmest area, the Antarctic Peninsula.

Australia would be an MEDC (more economically developed country) due to the fact that Australia is quite a wealthy country.

The sun is farthest north of the Equator during the summer solstice, which occurs around June 21st each year, and farthest south during the winter solstice around December 21st.
