Integral to the story of the origin of Antarctica’s name is that it was not named Terra Australis—this name was given to Australia instead, because of the misconception that no significant landmass could exist further south.

What was Antarctica called in the past?
Terra Australis
The history of Antarctica emerges from early Western theories of a vast continent, known as Terra Australis, believed to exist in the far south of the globe. The term Antarctic, referring to the opposite of the Arctic Circle, was coined by Marinus of Tyre in the 2nd century AD.
Was Australia originally part of Antarctica?
Australia began to separate from Antarctica 85 million years ago. The separation started slowly — at a rate of only a few millimetres a year — accelerating to the present rate of 7 cm a year. Australia completely separated from Antarctica about 30 million years ago.
How did Australia separated from Antarctica?
By the Late Cretaceous, about 84 Ma, Australia was separated from Antarctica by a seaway about 100 km wide. Tasmania was still connected to Antarctica.In the Late Cretaceous, 85-65 Ma, Tasmania was still connected to Antarctica by the stretched crust of the South Tasman Rise.

Has anyone been murdered in Antarctica?
Death is rare in Antarctica, but not unheard of. Many explorers perished in the late 19th and early 20th centuries in their quests to reach the South Pole, and potentially hundreds of bodies remain frozen within the ice. In the modern era, more Antarctic fatalities are caused by freak accidents.
Who opened Antarctica?
The race to find Antarctica sparked competition to locate the South Pole—and stoked another rivalry. Norwegian explorer Roald Amundsen found it on December 14, 1911. Just over a month later, Robert Falcon Scott found it, too. He turned back with disastrous results.
How did aboriginals get to Australia?
Aboriginal origins
Humans are thought to have migrated to Northern Australia from Asia using primitive boats. A current theory holds that those early migrants themselves came out of Africa about 70,000 years ago, which would make Aboriginal Australians the oldest population of humans living outside Africa.
Why are Australia and Antarctica no longer connected?
By 90 to 100 million years ago Africa & Madagascar had split and India was moving north. Australia and Antarctica had just separated.Antarctica became cooler and Australia became drier because ocean currents circling Antarctica were no longer directed around northern Australia into the subtropics.
Was Australia once connected to Africa?
Gondwana, also called Gondwanaland, ancient supercontinent that incorporated present-day South America, Africa, Arabia, Madagascar, India, Australia, and Antarctica.
Why is Australia the oldest continent?
Australia is “older” because much of it is little changed from the early days of the Earth. In places, later sediments were deposited only to be eroded away again, once again exposing the ancient land surfaces, which are again subjected to erosion.
Is Australia moving closer to Antarctica?
No, Australia and Antarctica are slowly moving apart, as they have been for the last 45 million years or so. Australia is currently moving north toward the Philippines while Antarctica is moving north on the other side of the globe toward Africa and South America.
What animal is only found in Australia?
Among the endemic animal species – species that can only be found in Australia – are the monotremes, which are mammals that lay eggs! The platypus and two species of echidna are the world’s only egg-laying mammals, so called monotremes.
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.
What flag is Antarctica?
Antarctica has no universally-recognized flag as the condominium that governs the continent has not yet formally selected one, although some individual Antarctic programs have formally adopted True South as the flag of the continent. Dozens of unofficial designs have also been proposed.
When did Antarctica freeze?
about 34 million years ago
Antarctica hasn’t always been covered with ice – 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.
What is illegal in Antarctica?
Other types of crimes that have occurred in Antarctica include illicit drug use, torturing and killing wildlife, racing motorbikes through environmentally sensitive areas, assault with a deadly weapon, attempted murder, and arson.
Are drugs legal in Antarctica?
The Antarctic Treaty forbids anyone of any citizenship from doing things like setting off nuclear bombs, but it has nothing to say about the consumption of cannabis (or any other drug, for that matter). So growing, consuming, or selling pot is technically legal. There’s no law saying you can’t.
Has anyone been born in Antarctica?
Eleven babies have been born in Antarctica, and none of them died as infants. Antarctica therefore has the lowest infant mortality rate of any continent: 0%. What’s crazier is why the babies were born there in the first place. These weren’t unplanned births.
Why has Antarctica not been explored?
Antarctica was actually discovered by accident. No one knew that this large area of ice and snow existed until it was first spotted in 1820. It wasn’t until 20 years later that Antarctica was confirmed a continent and not just a group of islands.
When was Antarctica warm?
The Cretaceous, 145m to 66m years ago, was a warm period during which Earth had a greenhouse climate and vegetation grew in Antarctica. Scientists say the new discovery not only reveals that swampy rainforests were thriving near the south pole about 90m years ago but that temperatures were higher than expected.
