Why cant a person in Antarctica use the big dipper to find the north direction?
The Big Dipper is not visible from Antarctica. As a person goes south of the equator, the stars in the northern hemisphere drop from view. When one crosses the equator, Polaris drops from sight. As one continues from sight Ursula Major and Cassiopeia vanish. There goes the Big dipper.
Where is the coldest and most desolated region on earth?
The coldest and most desolated region on earth is Antarctica. It is the coldest continent with temperatures dropping below -80°C (-112°F) and vast uninhabited areas covered by ice sheets and glaciers. The interior of Antarctica is considered one of the most desolate places on the planet due to its extreme cold, isolation, and harsh conditions.
What will happen to the North Pole if global warming continues?
Hot or cold there will always be a north magnetic and a north geographic pole on Earth. The environment in these areas may change through the warming processes of global climate change as well as ice cover and sea level but the poles will remain.
What continent at the South pole is sparsely populated?
Antarctica is the continent located at the South Pole and is sparsely populated, with only a few thousand researchers and support staff living there temporarily. The harsh climate and remote location make it unsuitable for permanent human habitation.
Are the glaciers melting in antarctica?
Antarctica is a continent and continents do not melt.
The ice sheet that covers 98% of the continent thaws and freezes annually. Extraordinary thawing is currently taking place under the ice shelves -- primarily in the Weddell Sea -- based on warming ocean waters which cause the ice shelf to decay.
Why does it stop snowing in antarctica?
Technically yes, on the peninsula jutting out of the continent rain is relatively common, happening on a yearly basis. However, anywhere more than several miles inland nearly never sees rain, and the actual magnetic south pole has never seen rain.
Where was Antarctica 500 billion years?
500 billion years ago, planet Earth didn't exist. The Universe didn't even exist for such a long time; the age of the Universe is estimated at about 14 billion years.

Can ice cream melt in Antarctica?
Yes, ice cream can melt in Antarctica if exposed to high enough temperatures, such as inside a warm building. While the outside temperature is extremely cold in Antarctica, indoor temperatures are typically kept above freezing to prevent water pipes from freezing.
What type of volcano is mount terror?
Mount Terror is a stratovolcano, which is a tall, conical volcano composed of layers of hardened lava, tephra, and volcanic ash. It is located in Antarctica and is part of the active volcano chain known as the Terror Rift.
Relate the movement of continental glaciers to why they cover antarctica and most of Greenland?
Continental glaciers form when snow accumulates over time in areas where the rate of snowfall exceeds melting. In Antarctica and Greenland, the extremely cold temperatures and high snowfall rates result in the continuous accumulation of snow over centuries, gradually forming thick ice sheets that cover the landmasses. The weight of the accumulated ice causes the ice to flow outward, forming continental glaciers that cover much of Antarctica and Greenland.
On which continent is the South Pole loacaded?
Well, since the North Pole is located at the "top" of the world, the South Pole is located at the bottom. A continent that is on the bottom is . . .
Antarctica!
Hope that helps! :)
How is the climate in the south pole?
The North Pole is significantly warmer than the South Pole because it lies at sea level with winter temps in January ranging from −43° C(−45° F) to −26° C(−15° F) and averaging around −34° C(−29° F), while summer temps average around the freezing point(0° C, 32° F).
What is Continental Divide of Antarctica?
The Continental Divide of Antarctica is a geographical feature that separates the ice flowing towards the Weddell Sea and the ice flowing towards the Ross Sea. It marks the boundary between the East Antarctic Ice Sheet and the West Antarctic Ice Sheet.
Does hypothermia relate to Antarctica and if so how?
Hypothermia is a human state that occurs when body temperature slips below normal. Since Antarctica is a polar continent -- the coldest on earth -- developing hypothermia is possible each time a human ventures out of doors or finds himself or herself without supplemental forms of heat.
Why north and south pole always ice?
The North and South Poles are covered in ice because they receive less direct sunlight due to the tilt of the Earth's axis. This causes colder temperatures and allows ice to accumulate and remain frozen year-round. Additionally, the cold temperatures at the poles prevent much of the ice from melting.
What kind of plant grows in Antarctica?
North of the Antarctic Peninsula there are moss carpets, only two species of native vascular plants, and lichen may occur in some places. For the rest of Antarctica, patches of tussock grass on islands north of the pack ice.
How many sheets of ice cover antarctica?
Antarctica is covered by a single, massive ice sheet that contains about 70% of the world's fresh water in the form of ice. This ice sheet is several miles thick in some places and holds an estimated 90% of the world's ice.
How close to the South Pole is Vinson Massif?
Vinson Massif is located at 78.6341° S and the South Pole is located at 90° S. Calculated in a straight line, the distance is 784.2471 miles between those two points.
Why is there so much snow in Antarctica and it doesn't precipitate a lot?
It's complex:
http://www.antarcticconnection.com/antarctic/science/meteorology.shtml
"The Antarctic continent is named for "opposite of the Arctic" and is literally in many ways quite different from its northern counterpart. The Arctic consists of the ice-covered Arctic Ocean surrounded by many islands and the northern fringes of the Asian and North American continents. On the other hand, Antarctica is a high, ice-covered land mass surrounded by the southern extensions of the Atlantic, Pacific, and Indian Oceans. As a result of these differences, the climates of the two regions are very different.
# Precipitation, nearly all as snow, occurs frequently over much of Antarctica, but is light.
# The total fall varies considerably from year to year. The scantiness of the snowfall is evident on the polar plateau, where over large areas annual amounts are less than 3 centimeters (water-equivalent).
# Annual snow accumulation on Ross Island averages 17.6 centimeters in water equivalent, but accumulation over the polar plateau to the west of the Dry Valleys is considerably less.
# Within the Dry Valleys most of the snowfall is associated with humid easterly winds blowing off the Ross Sea.
# More solar radiation reaches the surface at the South Pole than is received at the equator in an equivalent period.
# Total annual radiation at the South Pole is about equal to that received in equatorial regions, despite there being 6 months of "night."
# This is largely explained by the continent's high elevation, and its thin atmosphere, and by the air's unusual clarity.
# MOST OF THIS HEAT IS REFLECTED BACK INTO THE ATMOSPHERE BY THE SNOW-COVERED ICE SHEET AND THE GREATER EXPANSE OF SEA ICE." (emphasis added)
Can you eat the ice in Antarctica?
It is not recommended to eat ice in Antarctica due to potential contamination from pollutants and microorganisms. The ice in Antarctica can also be extremely cold and dense, which may not be safe for consumption. It's best to bring your own food and water when visiting the continent.
What are countries that have the same climate as the Antarctica?
Northern European countries such as Northern France, Belgium, Holland, Germany, Austria. In the Southern Hemisphere, South Island of New Zealand, Tasmania, South Africa, Argentina.
How thick are ice caps over some parts of Antarctica?
The Arctic ice cap consists of sea ice and the Greenland ice sheet . Sea ice can be several meters thick, while the Greenland ice sheet is several thousand feet thick in the interior.
Sea ice and ice sheets are two entirely separate things. The main being that ice sheets are formed from accumulated snow and are therefore entirely fresh water, while sea ice is frozen sea water. However, any salt that gets frozen into the ice - which itself is trapped in brine (liquid) pockets rather than incorporated into the crystalline structures - drains out with time.
Are People Trying To Respect Antarctica?
Yes, countries around the world have signed the Antarctic Treaty System to protect Antarctica's environment and wildlife while allowing peaceful research activities. However, increasing tourism and resource exploration pose challenges to maintaining the continent's pristine nature. Efforts are being made to reinforce regulations and educate the public on the importance of respecting Antarctica.
How is marine life in antarctica?
Marine life in Antarctica is diverse and unique, with species adapted to the extreme cold temperatures. Iconic animals include penguins, seals, whales, and krill. The ecosystem is sensitive to climate change and human impact, making conservation efforts crucial for preserving this delicate environment.
Is the Arctic made up of land covered by ice?
Antarctica is land covered by ice while the Arctic is just a solid piece of ice.
the statement above is...WRONG!! The arctic is mostly land. Yes it has ice, but mostly land.
The antarctic is 98 percent ICE. So really nethir are "completely" ice, but antarctica is the winner.
