What is the coldest Antarctica has ever been?
The warmest temperature ever was 59 degrees Fahrenheit. This was recorded along the peninsula, at a lower latitude than the rest of the continent. The weather here is quite different from the brutal cold of the interior.
How scientists get goods in Antarctica?
Supplies are brought to the continent either by airplane or by ship.
How do snow petrels breed in Antarctica?
Snow petrel is the southern-most breeding bird, because it breeds on the Antarctic continent. It does not live there. It's food chain is in the sea, which is true of all the animals that breed on Antarctica's beaches.
What caused a hole in the ozone layer above Antarctica?
An ozone hole forms when there is no UV-C from the Sun to replace the decay of ozone (both natural and man-caused). This occurs when the pole is having winter.
Antarctica's hole (South pole) is larger than the arctic hole (North pole), because the Earth's magnetic field directs positive charges from the solar wind to it, which is primarily hydrogen, and hydrogen oxidizes to water vapor, which decays ozone. The north pole gets almost exclusively electrons, which tend to make a bit more ozone, although indirectly.
See "Why is an ozone hole formed only above Antarctica and not over developed countries that emit a lot of CFCs?" in the "Related questions" section below.
How much will the sea level rise if the ice in the Arctic and Antarctica melts?
The ice at the North Pole is floating ice, so its melting will not raise the sea levels. The Greenland ice cap, and any other ice on land in Polar regions will raise the sea levels.
According to the Third Assessment Report of the International Panel on Climate Change, the ice contained within Greenland Ice Sheet represents a sea-level rise equivalent of 7.2 metres. The ice contained within the Antarctic Ice-sheet represents 61.1 metres of sea-level change.
That is, if both the Antarctic Ice-Sheet, and the Greenland Ice-Sheet were to melt, sea-level would rise by 68.3 metres.
What is the highest average temperature in Antarctica?
Antarctica is a continent that covers 10% of the earth's surface. The highest average temperature is well below zero F. This is also the location for the lowest temperature ever recorded on earth.
Antarctica is the coldest continent.
Why do bats not live in Antarctica?
No. There is no food chain for bats in Antarctica, and it's too cold for these animals.
How much fresh water is held in Antarctic Ice Sheet in the Southern Hemisphere?
70% of the worlds fresh water and 90% of the worlds ice is stored in the Antarctic ice sheet.
Where abouts do krill live in antarctica?
Krill live in the southern oceans. but one type called the Antarctic Krill does live in of course the antarctic. Euphausia superba, makes up an estimated biomass of over 500,000,000 tonnes (490,000,000 LT; 550,000,000 ST), about twice that of humans. more than half is eaten by whales, seals, penguins, squid and fish every year, but they are replaced by reproduction. Most krill species have large daily vertical migrations, by doing this they provide food for many other animals.
the two main reasons to research Antarctica is first, the ice under the surface is a time-line of the earth's atmosphere. Antarctica is a dessert and little precipitation and allows for a graphic time-line when drilled out in cores. Secondly, the atmosphere around the poles is important in measuring the global warming and the fear of the rising oceans because of glacial melting.
What are some difficulties people will face living and working in antarctica?
v Antarctica is the coldest, driest, and windiest place on Earth. The lowest temperature ever recorded was -89.6 degrees Celsius. Wind speeds during gales can reach 320km per hour. The average wind speed is over 70km per hour. These conditions can be a difficulty because of the cold, windy weather. v If you are not wearing enough warm clothing while you are at Antarctica, it could result in frostbite. Frostbite is when your body gets so cold, that your fingers and toes could turn black and fall off. v No roads make it hard to locate your position on a map. v Twenty-Four hours of sunlight can make it hard to get some sleep!!!! - Four months of the year, Antarctica receives constant sunlight! - In July there is no daylight at all, which is a difficulty because it would be hard to see, and it would be colder, but obviously nobody would choose to go to Antarctica during that difficult stage. People pretty much only go to Antarctica during the Summer.
What are the houses in antarctica built of?
Your answer depends on the type of structure being built.
Research station buildings are built using common building materials, all of which are imported to the continent. Wood, glass and metal are most common.
In an emergency, a person can carve ice bricks from the ice sheet and fashion an igloo.
Which 7 countries own parts of Antarctica?
No country owns any part of Antarctica.
All land and ice south of 60 degrees S is governed by the Antarctic Treaty (1961), and is preserved for the scientific study of the health of planet earth.
Nations including Great Britain, New Zealand, Australia, Chile, Argentina, France and Norway claim territory on the continent, and some of these claims overlap each other. The treaty holds all these claims in abeyance and prohibits future claims.
Is there an airport on Antarctica?
There is no commercial air service to anywhere on Antarctica.
Landing fields used by government logistical deliveries and exportations can be land, or more commonly ice field runways. Aviation controllers familiar with the military logistical equipment aid in takeoffs and landings.
What impact does mining in antarctica have?
Another Answer
There is no mining in Antarctica.
The environment is too extreme, cold and isolated to make mining any kind of a sound financial investment. This is in addition to it being banned under The Antarctic Treaty.
Antarctica is a continent for science shared among nations representing 80% of the earth's population.
_______First Answer_______ well, firstly mining is illegal until 2041 and was banned by the antarctic treaty in 1991.
scientists already know that there is a big hole in the ozone layer that appears every spring, by mining antarctica we are only making the hole bigger
also it will destroy animals habitats such as penguins and seals
breeding will be hard for them. also mining will poison waters and will destroy half of the land, this will kill seals, whales and penguin and fish and others
although we do not have enough resources to last until 2048 so if we mine there we can drive cars in and use computers and other things. there is a large quantity of oil which is needed, although if we let mining people will fight over it, as people are fighting for oil in Iraq
there is also
- Silver
- Gold
- Cobalt
- copper
- Chromium
- Iron
- Molybdenum
- Manganese
- Nickel
- Lead
- Titanium
- Uranium
- Zinc
soon there will probably be another gold rush if we really need gold even though there is not that much
transport to and from antarctica would be very expensive alone and with all the other fees
there will be another depression.
i have more information, if you want i can give more later!
What is the longest number of days a person(s) has spent in Antarctica at one time?
Each government has a different maximum number, but generally, a temporary worker can remain 'on the ice' for up to 12 months, and then a six-week break 'off the ice' is required in order to return to Antarctica.
What is the location of the Casey research station in Antarctica?
Bellingshausen Station is a Russian research station located on King George Island, one of the South Shetland Islands.
Like all scientific research stations south of 60 degrees S, it is governed by the Antarctic Treaty. This means that all the work there is scientific work that studies the health of planet earth.
How many blizzards are there a month in antarctica?
Generally, across the Antarctic continent, the wind is constant. Blizzards occur frequently, depending on where you are on the continent. One could assume that there may be a blizzard every day somewhere in Antarctica, especially during the Fall, Winter and Spring months. Blizzards also occur during the Summer there.
What region is it in eastern Antarctica?
An article (abbreviatedart) is a word (or prefix or suffix) that is used with a noun to indicate the type of reference being made by the noun. Articles specify grammatical definiteness of the noun, in some languages extending to volume or numerical scope. The articles in the English language are the and a/an, and (in some contexts) some. 'An' and 'a' are modern forms of the Old English 'an', which in Anglian dialects was the number 'one' (compare 'on', in Saxon dialects) and survived into Modern Scots as the number 'ane'. Both 'on' (respelled 'one' by the Normans) and 'an' survived into Modern English, with 'one' used as the number and 'an' ('a', before nouns that begin with a consonant sound) as an indefinite article.
Traditionally in English, an article is usually considered to be a type of adjective. In some languages, articles are a special part of speech, which cannot easily be combined with other parts of speech. It is also possible for articles to be part of another part of speech category such as a determiner, an English part of speech category that combines articles and demonstratives (such as 'this' and 'that').
In languages that employ articles, every common noun, with some exceptions, is expressed with a certain definiteness (e.g., definite or indefinite), just as many languages express every noun with a certain grammatical number (e.g., singular or plural). Every noun must be accompanied by the article, if any, corresponding to its definiteness, and the lack of an article (considered a zero article) itself specifies a certain definiteness. This is in contrast to other adjectives and determiners, which are typically optional. This obligatory nature of articles makes them among the most common words in many languages-in English, for example, the most frequent word is the.[1]
Articles are usually characterized as either definite or indefinite.[2]A few languages with well-developed systems of articles may distinguish additional subtypes.
Who was the first man to fly over Antarctica?
On February 4, 1902, British Navy Captain Robert Falcon Scott made the first flight over the world's most remote continent. Scott went aloft in a tethered hot-air balloon off the Antarctic Coast.
What did Robert Falcon Scott take to Antarctica?
Captain Scott trekked from his base locations on McMurdo Sound to the South Pole.
Why would your heartbeat return to normal if you flew from there to the Ross ice shelf?
Because of climate change your heart finds it easier to pump blood around the body
Another Answer
Throughout the experience, your heart rate would be normal, except for emotional reactions you may have to being in flight, or observing the breath-taking vistas, in which cases, your heart rate would increase.
What tools do explorers use in Antarctica?
lots of stuff, warm clothing. Boots, proper boots designed for ice, a compass, maybe some form of moving around other than walking like a snowmobile?? lots of food and water
