What is antarctica water temp?

The water temperature in the Southern Ocean that surrounds the Antarctic continent varies down to about 28 degrees F, because of the minerals contained in the water. Fresh water freezes at 32 degrees F. The high water temperature in this ocean can reach 50 degrees F.

How much fresh water and ice does antarctica have?

All the fresh water in Antarctica is frozen. The ice sheet that covers 98% of the continent contains about 70% of the earth's store of fresh water. As well, it contains about 90% of the earth's store of ice.

Is Antarctica located at the top of the world?

Antarctica is located at the bottom of the earth but the northpole is at the top of the earth

What mountain range separates Antarctica into Greater and Lesser Antarctica?

The "Transantarctic Mountains" divide east and west Antarctica. The mountain range probably got that name because it spans the continent.

How did Antarctica become the coldest continent?

the continent lay over the south pole without freezing over for almost 100 million years. Then, about 34 million years ago, a dramatic shift in climate happened at the boundary between the Eocene and Oligocene epochs. The warm greenhouse climate, stable since the extinction of the dinosaurs, became dramatically colder, creating an "ice-house" at the poles that has continued to the present day.

Why does Antarctica have so much night time?

Picture the Earth and the sun. The sun's rays go straight through space. The first thing the rays of the sun touch is the equator. The last things the rays hit are the north and south pole. The above accounts partly for the low temperatures in Antarctica, but it is the earth's tilt that is responsible for the long nights.

During summer, Antarctica actually has a lot of daylight hours as the sun never sets. This is caused by the same reason in reverse that results in the long winter nights. If the southern hemisphere is tilted away from the sun, as happens during winter, the latitude of Antarctica is so high that the sun never rises for a number of weeks or months. When it is tilted toward the sun, it does not experience a sunset for a time.

What is the GDP of Antarctica?

Antarctica has no 'income', no economy, no permanent population,, government or gross national product. Antarctica is a continent dedicated to science. All temporary workers there are supported by governments representing 80% of the earth's population.

What are the valid occupations on Antarctica?

Scientists interested in answering questions about the health of planet earth offer examples of 'valid occupations' on Antarctica. For each funded scientist, there are about seven people who support science. These occupations include those involved with science, food, human health, logistics, administration and so forth.

Is Pacific Ocean a part of Antarctica?

No. Antarctica is a continent surrounded by the Southern Ocean, the extent of which is poorly defined insofar as its join with the Pacific Ocean.

What are some current concerns for Antarctica?

Modern issues include ozone loss (which is recovering) as well as environmental changes which are impacting flora and fauna. Plant and animal life only exist on the coast, where temperatures have been rising as a result of global warming in both the ocean and the atmosphere as well as increasing ocean acidity. This has led to some concern, particularly to the population of many species of penguin, which have been decreasing in numbers.

What dangers can occur to humans in antarctica?

Expedition dangers include, and are not limited to:

  • Freezing body parts, including the whole body
  • Falling into a crevasse with no hope of being rescued
  • Starving to death because of low caloric intake
  • Going mad because of the isolation, cold, wind. darkness, dryness, or other
  • Failing to achieve safety at any point
  • Depending on equipment provided by the lowest bidder, which equipment fails.

What is Antarctica's national dish?

There is no society or culture in Antarctica; hence no 'traditional dish'.

What is a large piece of ice that covers land?

A large piece of ice that covers land is called an Ice Sheet.

What month is summer autom winter and spring in antarctica?

Good question...there are 6 months of light (Sept 22 - March 21) and then 6 months of darkness. So if you want to call 6 months of light the summer then there is your answer. In fact everyplace on earth receives exactly 6 months of light and 6 months of darkness although it is usually spread out throughout the year. Short days and long nights in winter and long days and short nights in summer, but a total of 6 months of each. Antarctica has all 6 months of light at the same time. From THEIR Vernal equinox to THEIR autumnal Equinox. This could be considered their summer hope it helps

Who descovred Antarctica?

Captain James Cook was the first to cross the Antarctic Circle on the 17th of January, 1773, and reached a latitude of 67 degrees 15 minutes S. It is not clear whether or not he actually set eyes on Antarctica since the ice pack prevented any further southward progress. In January, 1820, as a result of an earlier expedition where he was blown off course, the British Royal Navy sent William Smith as pilot with Edward Bransfield to search the waters south of the newly claimed South Shetland Islands. It is subsequently claimed that they are the first to see the Antarctic Peninsula. On the 27th of January, 1820, Russian, Fabian Gottlieb von Bellinghausen, becomes the first person to see the Antarctic continent. In January,1821, Bellingshausen returns to the Antarctic and completes a circumnavigation of Antarctica being only the second explorer, after Cook, to do so. In February, American sealer John Davis arguably becomes the first person to land on the Antarctic continent. A Norwegian scientist immigrant to Australia, Carsten Egeberg Borchgrevink (1864-1934), became the first man to set foot on the Antarctic when he stepped on to Cape Adare on the 24th of January, 1895. From 1894-95 he devoted his time to exploration of Antarctica. He attempted to reach the South Pole in 1897. During this expedition, he was the first to discover lichen in the Antarctic, and reached a latitude of 78 degrees 5 minutes S.

Do play bears live in Antarctica?

No.

Antarctica is too cold to support animal life, and there is no food chain there.

Is Antarctica the most dangerous place on Earth?

Every place on earth is dangerous -- if you're unprepared, unaware of your surroundings, and have lost or compromised your survival skills in some way.

What is antarctica famous for?

Antarctica is known for being the highest, driest, darkest, coldest, iciest and windiest continent on Earth.

How high is Antarctica's tallest mountain?

You may be thinking of Mt Erebus, an active volcano.

What is the solution to the disposal of waste in Antarctica?

All waste generated on the continent -- including human waste from field camps -- is either burned on the continent, or sent back to the country that supports the research facility.
There is no way to prevent rubbish anywhere, but how it's handled can prevent it from polluting the geography where it's produced.

Why are tourists attracted to Antarctica?

Tourists Want To Go To Antarctica For The Exhilerating Feeling Of The Fact Your Standing, On The Bottom of the Earth, tourists also would like to go to Antarctica For The Delicate Scenery of the Ice landscape, and the amazing environment.

Does Antarctica have seasons?

Antarctica has four seasons, as does every spot on earth.

Seasonal changes occur on December 21, March 21, June 21 and September 21.

Because Antarctica is in the southern hemisphere, its seasons are reversed from the seasons named in the northern hemisphere. For example, June 21 is called Mid-Winter's Day in Antarctica, and technically December 21 is the longest day of the year.
yes but they are much more extreme than most of the rest of the planet.

Summers are bright all day and night and winters are dark all day and all night.

What are the special features of Antarctica?

Antarctica is Earth's southernmost continent, underlying the South Pole. It is situated in the Antarctic region of the southern hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean.

At 14.0 million km² (5.4 million sq mi), it is the fifth-largest continent in area after Asia, Africa, North America, and South America. About 98% of Antarctica is covered by ice, which averages at least 1.6 kilometres (1.0 mi) in thickness.Antarctica, on average, is the coldest, driest, and windiest continent, and has the highest average elevation of all the continents.

Antarctica is considered a desert, with annual precipitation of only 200 mm (8 inches) along the coast and far less inland.

There are no permanent human residents but anywhere from 1,000 to 5,000 people reside throughout the year at the research stations scattered across the continent.

Only cold-adapted plants survive there, including mosses, lichen, and many types of algae. Sea mammals and sea birds breed on Antarctica's beaches.

The name Antarctica is the romanized version of the Greek compound word antarktik, feminine of antarktikos, meaning "opposite to the north".

Although myths and speculation about a Terra Australis("Southern Land") date back to antiquity, the first confirmed sighting of the continent is commonly accepted to have occurred in 1820 by the Russian expedition of Mikhail Lazarev and Fabian Gottlieb von Bellingshausen.

The continent, however, remained largely neglected for the rest of the 19th century because of its hostile environment, lack of resources, and isolation. The first formal use of the name "Antarctica" as a continental name in the 1890s is attributed to the Scottish cartographer John George Bartholomew.

The Antarctic Treaty was signed in 1959 by twelve countries; to date, forty-six countries have signed the treaty. The treaty prohibits military activities and mineral mining, supports scientific research, and protects the continent's ecozone.

Ongoing experiments are conducted by more than 4,500 temporary workers, including scientists of many nationalities and with different research interests. Every experiment or data gathering expedition focuses on learning more about the health of planet earth.
