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.
Is there a telephone pole at the US base in Antarctica?
No, there are no telephone poles at the US base in Antarctica. Communication at the base is typically through satellite phones, internet, and radio due to the harsh environment that prevents the use of traditional telephone poles.
Why do they dig ice cores in antarctica?
Ice cores are used to examine the different levels of atmospheric gas, levels of dust, and also levels of solar radiation affected by both gas and dust. this allows scientists to examine what the atmosphere was like hundreds of thousands of years ago. Each layer shows a different period of time in the cycle of climate change.
Can a pole shift cause the continents to move?
A pole shift refers to a change in the Earth's rotational axis, which can affect the distribution of land and sea but does not cause the continents to physically move. Plate tectonics are responsible for the movement of continents over long geological timescales.
In antarctica what is the average temperature in June?
In Antarctica, the average temperature in June can vary depending on the region. However, generally, temperatures can range from -15°C to -60°C during this month, making it one of the coldest months of the year in Antarctica.
What is the night sky called in antarctica?
sometimes, a glow in the night sky may be observed near the south pole. This is called as aurora australis. This is created by the emissions of photons in the Earth's upper atmosphere. from oxygen and nitrogen items. Oxygen emissions are green or brownish red and nitrogen emissions are blue or red.
Which continent has no permanent inhabitants?
Antarctica is the continent with no permanent inhabitants, although it does have temporary residents such as scientists and researchers who work in research stations.
Where is most of the bare rock found in Antarctica?
Most of the bare rock in Antarctica is found along the mountain ranges and exposed ridges, particularly in areas like the Transantarctic Mountains and the Antarctic Peninsula. These regions have rocky outcrops and nunataks that are not covered by ice or snow, allowing for the exposure of bare rock.
Is it dark or light in antarctica?
the earth axis of rotation isn't exactly vertical, but a little tilted. When one hemisphere has winter their part of the axis is pointing away from the sun, putting the region closest to the pole in constant shadow.
What contenent is south of the four major oceans of the world?
Antarctica is located south of the four major oceans of the world: the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, and the Southern Ocean.
Does Antarctica have a dry and wet season?
Antarctica does have a dry and wet season, but the wet season consists mainly of snow. It doesn't rain in Antarctica, and Antarctica is a desert, so there is not much snow.
Another Answer
Antarctica is a desert and thus has no wet season.
How much does Antarctica shrink each year?
Antarctica is losing approximately 118 gigatons of ice per year, leading to an annual sea-level rise of 0.3 millimeters. The rate of ice loss has been increasing over the past few decades due to climate change.
What minerals have been found in Antarctica in significant amounts?
There is no land under the North Pole, it is just floating ice. There is land at the South Pole but the ice is so deep and the conditions so harsh that it probably wouldn't be economical to try and extract any minerals that might be there.
Is Antarctica in the north or south hemisphere?
Antarctica is in the Southern Hemisphere, not the Northern Hemisphere. As well, parts of it are in the Eastern and parts in the Western Hemisphere.
It is a continent at the south pole were penguins live?
Yes, the South Pole is on the continent of Antarctica. Note, however, that penguins are sea birds and make their homes in ocean waters. They breed, however, on Antarctica's beaches, because there are no land predators there.
