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.
Why does Antarctica have wind speeds up to 300Km?
The wind speed you quote is an exaggeration.
The top wind speed measured on the continent is just under 200Km per hour. It is caused by the Katabatic winds that fall downhill from the polar plateau, which is about 2,835m above sea level. These winds are caused by gravity and the rotation of the earth.
In what continent is Mt Erebus located?
The active volcano Mount Erebus is located on Ross Island, which also home to three inactive volcanoes, on the continent of Antarctica. Mount Erebus is part of the Pacific Ring of Fire which is an area of the Earth that has 160 active volcanoes.
How deep is the ice in the Antarctic?
The Southern Ocean that surrounds the continent of Antarctica can measure 27 degrees F before freezing, based on the high mineral content of the water. During the winter, the ocean water freezes, essentially doubling the size of the Antarctica.
The water temperature consistently hovers around freezing.
What percent of Antarctica has melted from global warming?
Actually yes, the earths ice caps are melting but at a slow rate, we do not know if it is to cause an alarm just yet however. We believe "Global Warming" has contributed to the ice caps melting but further study is needed.

Why doesn't Antarctica float away?
Antarctica is a continent covered in ice sitting on the Earth's solid crust, so it is anchored to the bedrock below. The weight of the ice sheet helps keep it in place, preventing it from floating away. Additionally, the continent's mass prevents it from being easily moved by external forces.
How long until the ice cap of Antarctica melts?
in 4 to 10 years
in 4 to 10 years
Since about 20,000 years ago when the last ice age, or glacial period, reached it's peak, after that the caps began to melt, receding from the states of america, northern europe, northern-mid asia etc, which lead to flooding all around the world which caused things like the flooding of the land which connected england and france etc.
Although it has been melting steadily over the millenniums, scientist who are paid to investigate continuously on why the world is getting warmer have come to the conclusion that CO2(carbon dioxide) from cars and coal power plants etc are causing the planet to warm faster, even though sufficient evidence has not been presented.
As of right now, the south pole and the caps around green land are melting in the summer and freezing in the winter.
there were also a few periods in history that were called "the little ice age" or "the little ice ages" which caused famine and starvation in the not too distant past, and "the medieval warm period" which lasted about 300 years which was before the little ice age.
How could the ice caps form in Antarctica if it is a desert?
That an area is a desert does not mean that it is hot, just that there is very little precipitation. Antarctica gets very little snow, but it is cold enough that what little snow falls never melts. It has been like this for millions of years, allowing the snow to pile up and compress into ice sheets several miles thick.
Why does high biological productivity occur around Antarctica?
High biological productivity around Antarctica is driven by the upwelling of nutrient-rich waters due to strong winds and ocean currents in the region. These nutrients support abundant phytoplankton growth, which in turn sustains a diverse food web including krill, fish, and other marine species. The cold, nutrient-rich conditions also help to support large populations of seabirds and marine mammals in the area.
Greenland is an island and Antarctica is a continent, both covered with ice sheets.
How many countries are there in Antarctic treaty?
First signed in December 1959, by the 12 countries that took part in the international Geophysical Year of 1957-58, they were Argentina, Australia, Belgium, Chile, France, Japan, New Zealand, Norway, South Africa, the Soviet Union, the United Kingdom and the United States.
The 12 original countries have over the years been joined by other countries. the total now stands at 41 countries who have signed the Treaty.
What is winds that blow off the ice sheets of Antarctica and Greenland are?
The winds that blow off the ice sheets of Antarctica and Greenland are known as katabatic winds. These downslope winds are dense and cold, originating from the high ice sheets and flowing towards lower elevations due to gravity. Katabatic winds can have significant impacts on local weather and climate.
How much of the earth's ice is in Antarctica?
The Antarctic ice sheet contains about 90% of earth's ice.
What is the name of the Research Station located at the South Pole?
The Indian station for Arctic Research is called Himadri, and the station is at Ny-Alesund in Norway, which is the northern-most permanent human settlement, 1,200 km from the North Pole, opened in 2008.
The Arctic Circle (66.5 degrees North) marks the latitude where the sun doesn't set at least once in summer. The Antarctic Circle (66.5 degrees South) indicates the latitude where the sun doesn't rise at least once in winter.
