How is global warming threatening the lives of Antarctic animals?
Global warming refers to the rise in the global temperature due to the Greenhouse Effect. Global warming effects Antarctica's marine life by raising the temperature of the water, so that a lot of the fish are dying.
Why the ice in the Antarctica does not melt away into the sea when sunlight shines on it?
The reason the ice in the Antarctica does not melt away when sunlight shines upon it is because the whiteness of the ice reflects most of the light back into space. But as a result of global warming, much more ice are being melted now than before. And thus without the ice, more sea will appear. And with the sea, there were not as much ice to reflect the sunlight back into space, therefore more of the sunlight and its heat were absorbed by earth, and thus more and more ice will melt.
Where do Antarctic explorers stay?
Explorers everywhere bring their own shelter and supplies with them on any expedition. In Antarctica, the best portable protection from the elements is a tent, often a Scott tent design. This shape -- like a pyramid -- withstands winds from every direction.
Which subregions of Antarctica are located in West Antarctica?
West Antarctica includes the Antarctic Peninsula and its offshore islands such as Adelaide Island, Marie Byrd Land, the Rockefeller Plateau, the Hollick-Kenyon Plateau, and a host of ice shelves such as the giant Filchner-Ronne Ice Shelf on the Weddell Sea, and the Ross Ice Shelf.
Why is there no mining in Antarctica's mineral minerals?
Mining in Antarctica is prohibited under the Protocol on Environmental Protection to the Antarctic Treaty due to concerns about preserving the pristine environment and preventing pollution. The extreme environmental conditions, logistical challenges, and minimal economic feasibility also contribute to the lack of mining activities in Antarctica's mineral-rich areas.
How many time zones in antarctica?
Well, there are 24 timezones - one for each hour of the day. Being as the timezones stretch from the North Pole to the South Pole, and the South Pole is in Antarctica, Antarctica has all 24 of them.
The dense ice sheets that cover Antarctica create?
The dense ice sheets that cover Antarctica create a reflective surface that helps to maintain cooler temperatures by reflecting solar radiation back into space. This also contributes to regulating global sea levels by storing a significant amount of freshwater in the form of ice. Additionally, the weight of the ice sheets can exert pressure on the underlying landmass, affecting the topography and geological features of the continent.
How does the height of Antarctica compare with the height of Mt Everest?
Mount Vinson is the highest peak in Antarctica, with an elevation of 16,066 feet (4,897 meters).
Mount Everest is the tallest mountain in the world, its stands at a height of 8,848 meters or 29.028 feet.
An ice shelf is a floating platform of ice that forms where a glacier or ice sheet flows down to a coastline and onto the ocean surface. The thickness of ice shelves can range from about 100 to 1000 meters (328 to 3280 ft).
Is Antarctica nearly all solid ice?
Yes, Antarctica is nearly all covered in a thick ice sheet. In fact, about 98% of Antarctica is covered by ice, which averages about 1.6 kilometers (1 mile) in thickness. The ice is so massive that it contains about 70% of the world's fresh water.
In which of the two major parts of antarctica is the south pole located?
The South Pole is located in the eastern part of Antarctica.
You can find Antarctica -- the Antarctic Peninsula -- about 750 miles south of the southern tip of the Argentine. Otherwise, it is also south of South America, and also south of India, south of Australia.
What imaginary lines forms the northern boundary of most of antarctica?
The imaginary line that forms the northern boundary of most of Antarctica is the Antarctic Circle, located at approximately 66.5 degrees south latitude. Beyond this line, there are restrictions on sunlight and daylight hours due to the tilt of the Earth's axis.
Does it snow all year round in Antarctica?
No, but because Antarctica is at such a low latitude the sun does shine and never sets for a few weeks in mid-summer. In mid-winter, they experience the opposite when the sun does not rise above the horizon at all.
If you would like to know the day length on any given day at any of the stations, go to the Web Link ' Australian Antarctic Division - Sunlight Hours' to the left.
Is Australia moving to Antarctica?
No, Australia is not moving to Antarctica. While Australia does have research stations and territorial claims in Antarctica, geographically Australia remains a separate continent located in the Southern Hemisphere.
How many meters thick is the thickest piece of ice?
The thickest piece of ice ever recorded was about 4,000 meters (13,000 feet) thick. This ice sheet is found in Antarctica and is known as the East Antarctic Ice Sheet.
What months does the ozone hole occur in antarctica?
The ozone hole in Antarctica typically occurs from September to November, with the largest depletion usually observed in October. This is during the Southern Hemisphere's spring when unique atmospheric conditions contribute to the formation of the ozone hole.
What is the coldest recorded on antarctica?
The coldest temperature ever recorded in Antarctica was -128.6 degrees Fahrenheit (-89.2 degrees Celsius) at the Soviet Union's Vostok Station on July 21, 1983. This extreme low temperature was measured using satellite data.
What is the diameter of the base of mt erebus?
Mount Erebus has a base diameter of approximately 30 kilometers.
Why are there cracks in the ice in Antarctica?
Icebergs calving off the Antarctic ice sheet is a normal phenomenon that has occurred for eons and will continue to occur. The weight of ice on the continent forms glaciers that push the ice sheets out over the ocean.
In recent years warming waters are undermining the ice shelves at the point where they reach the sea. This is known as basal melting.
What are some of the items Ernest Shackleton packed on his voyage to the south pole?
Ernest Shackleton packed essential items such as food provisions (biscuits, pemmican), clothing (woolen socks, fur mittens), equipment (tents, sleeping bags), medical supplies, navigation tools (sextant, compass), and personal items (diaries, photographs) for his voyage to the South Pole. He also brought sledges, skis, and dogs for transportation across the ice.
The average precipitation fall of the transantarctic mountains?
None.
Any rainfall in Antarctica is concentrated on the Antarctic Peninsula. The Trans-Antarctic mountains are too cold for rain. Plus, further inland, there is essentially no precipitation, that geography being a polar desert.
What continent is Brisbane and Queen Maud Land on?
Brisbane is on the continent of Australia.
Queen Maud Land is on the continent of Antarctica.
Does it snow a lot in antarctica compared to other countries?
Yes, Antarctica receives more snowfall than most other countries, with some areas averaging over 6 inches of snow per year. The interior of Antarctica is the driest place on Earth, but coastal regions can receive much higher amounts of snowfall.
What is the differences between Canada and antarctica?
Canada is a country located in North America with a diverse population, developed infrastructure, and a strong economy. Antarctica, on the other hand, is a frozen continent at the southernmost part of the Earth, uninhabited by humans and primarily used for scientific research. Canada has a government, cities, and communities, while Antarctica is mostly untouched wilderness.
