What are the main features of Antarctica?
Often described as a continent of superlatives, Antarctica is not only the world’s southernmost continent. It is also the world’s highest, driest, windiest, coldest, and iciest continent. Antarctica is about 5.5 million square miles (14.2 million square km) in size, and thick ice covers about 98 percent of the land.
What are two features of Antarctica?
There are two main characteristics that make Antarctica so great for meteorite enthusiasts: the white expanse and the ice drifts. The monochromatic landscape makes the dark rocks stand out, and the ice drifts tend to drop them all off in the same area.
Why Antarctica is a special area?
Antarctica is important for science because of its profound effect on the Earth’s climate and ocean systems. Locked in its four kilometre-thick ice sheet is a unique record of what our planet’s climate was like over the past one million years.
What are the major water features of Antarctica?
The Indian, Pacific and Atlantic Oceans surround it on all sides. Antarctica is surrounded on all sides by water; the Atlantic, Pacific and Indian Oceans all meet at Antarctica. The three oceans are collectively called the Southern Ocean. This is the area located south of 50° latitude.

Who governs Antarctica?
People from all over the world undertake research in Antarctica, but Antarctica is not owned by any one nation. Antarctica is governed internationally through the Antarctic Treaty system. The Antarctic Treaty was signed in 1959 by 12 countries who had scientists in and around Antarctica at the time.
What are 5 facts about Antarctica?
Why is Antarctica so important?
Why the Antarctic is so important It could be vital for our survival too. The Antarctic ice deflects some of the sun’s rays away from the Earth, keeping temperatures liveable. Antarctica is one of the world’s most important ‘natural laboratories’ – which is why so many scientists brave the cold to work there.
Do people live in Antarctica?
The people who travel to or live in Antarctica fall into two main groups, those who live and work on scientific research stations or bases, and tourists. No-one lives in Antarctica indefinitely in the way that they do in the rest of the world. It has no commercial industries, no towns or cities, no permanent residents.
What are 2 interesting facts about Antarctica?
Why is Antarctica so dangerous?
Winter temperatures plummet to about -100 degrees Fahrenheit, and that, combined with the world’s driest air, makes it a struggle to even climb a flight of stairs. The air causes instant pain to any exposed skin. It’s not even wise to smile—your gums and teeth will ache. Frostbite can set in quickly.
Is it illegal to live in Antarctica?
No-one lives in Antarctica indefinitely in the way that they do in the rest of the world. It has no commercial industries, no towns or cities, no permanent residents. The only “settlements” with longer term residents (who stay for some months or a year, maybe two) are scientific bases.
Why do planes not fly over Antarctica?
Firstly, there’s a lack of any real need to fly over the South Pole. There’s a lot less airline traffic in the far reaches of the southern hemisphere than the northern hemisphere. For example, the southern hemisphere doesn’t have the equivalent of those typically busy sub polar routes between North America and Asia.
Is Antarctica dangerous?
Climate change is the greatest long-term threat to the region. Some parts of Antarctica are experiencing significant ice retreat, including the collapse of ice shelves along the Antarctic Peninsula, while other areas are increasing.
Is there WIFI in Antarctica?
Yes, however internet access is limited at each USAP site. The satellite infrastructure used to provide off-continent communications in Antarctica is limited….Vessels.

Is there McDonald’s in Antarctica?
Did you know Antarctica is the only continent where McDonald’s restaurants are not located?
Can people live in Antarctica?
Antarctica is known for being the highest, driest, coldest and windiest continent on earth. Although there are no native Antarcticans and no permanent residents or citizens of Antarctica, many people do live in Antarctica each year.
Can you breathe in Antarctica?
This makes Antarctica the highest continent in the world and means there is less effectively available oxygen to breathe in Antarctica than on any other continent. This places the South Pole, and most of the Antarctic Plateau at high altitude.
Can you buy a house in Antarctica?
You cannot buy land in Antarctica. In particular, you cannot buy land in any way connected to the US, because the US has no territorial claims in Antarctica.
Is it illegal to go to Antarctica?
Antarctica is the only continent on Earth without a native human population. If you are a citizen of a country that is a signatory of the Antarctic Treaty, you do need to get permission to travel to Antarctica. This is nearly always done through tour operators.
Antarctica is the 5th largest continent on Earth with up to 98% of it being covered with thick ice and snow. Its unique position in the high latitudes of the Southern Hemisphere means that almost all of Antarctica has temperatures below freezing all year long.
What type of physical features does Antarctica have?
Antarctica is almost completely covered by an ice sheet. At its thickest, the ice is over 4 km deep. Beneath the ice sheet is a hidden landscape of mountains, valleys and plains. Antarctica’s dome-shaped ice sheet has been formed by snow.
What are the 12 countries in Antarctica?
The Antarctic Treaty was signed in Washington on 1 December 1959 by the twelve nations that had been active during the IGY (Argentina, Australia, Belgium, Chile, France, Japan, New Zealand, Norway, South Africa, United Kingdom, United States and USSR).
What are five physical features?

What are the most important features of Antarctica?
The majority of the islands and archipelagos of Lesser Antarctica are volcanic and heavily glaciated. They are also home to a number of high mountains. The oceans surrounding Antarctica provide an important physical component of the Antarctic region.
What are the special features of the Earth?
Earth’s special features! Ozone Layer. The ozone layer is a layer in Earth’s atmosphere containing relatively high concentrations of ozone. The ozone layer was discovered in 1913 by the French physicists Charles Fabry and Henri Buisson. Earth is the only planet with an ozone layer and the ozone layer keeps us safe from the sun.
Why is Antarctica more reflective than other continents?
Antarctica has a larger role than most continents in maintaining Earth’s heat balance. Ice is more reflective than land or water surfaces. The massive Antarctic Ice Sheet reflects a large amount of solar radiation away from Earth’s surface. As global ice cover (ice sheets and glacier s) decreases, the reflectivity of Earth’s surface also decreases.
What kind of climate is found in Antarctica?
Despite being covered in snow and ice, mean annual precipitation is very low, and the climate can be described as a polar desert.
