What caused Antarctica to freeze over?
The prime suspect is a gradual reduction of CO2 in the atmosphere, combined with a 'trigger' time when Earth's orbit around the sun made Antarctic summers cold enough for ice to remain frozen all year round.

How did Antarctica get covered in ice?
Over the next few hundred thousand years, glaciers began to creep down from Antarctic mountains, thickening and filling entire valleys, cloaking the continent in a blanket of ice.
When did Antarctica become icy?
about 34 million years ago The icing of Antarctica began in the middle Eocene about 45.5 million years ago and escalated during the Eocene–Oligocene extinction event about 34 million years ago.

Did Antarctica used to be warm?
Modern-day Antarctica hardly brings beaches and sunshine to mind. But according to new research, the continent and its surroundings used to be a much balmier place.
What is hidden under Antarctica?
Antarctica holds many secrets beneath its vast ice sheets – even a massive mountain range. Hidden below a two to four thousand kilometre thick sheet of ice are the Gamburtsev Mountains. They stretch for 1,200 kilometres and rise to 3,000 metres, a third of the height of Mount Everest.
What is buried under Antarctica?
Antarctica is hiding a huge amount of water beneath its surface. Researchers have long suspected that there might be groundwater buried beneath the ice, but until now there has been no conclusive evidence to confirm that suspicion.
Is there a hidden world in Antarctica?
There's a hidden world under Antarctica The hidden world was found over 1,640 feet below the surface of the ice in Antarctica. After drilling a hole through the ice, scientists dropped a camera into the hole. At the bottom, they noticed multiple blurry, tiny specks flashing in front of the video feed.
Did Antarctica used to be a jungle?
But roughly 90 million years ago, the fossils suggest, Antarctica was as warm as Italy and covered by a green expanse of rainforest. “That was an exciting time for Antarctica,” Johann P. Klages, a marine geologist who helped unearth the fossils, told Vox.
Did Antarctica ever have trees?
A forest high in Antarctica's mountains They found fossil fragments of 13 trees and discovered fossils of trees that are over 260 million years old, meaning that this particular forest was growing at the end of the Permian Period, before the first dinosaurs. At that time, Antarctica was still at the South Pole.
Is it illegal to live in Antarctica?
Access to Antarctica is restricted by the Antarctic Treaty. If you want to organize your own trip or expedition there, you will have to request permission from the government of your own country.

Well, that is because visiting Antarctica is a privilege and a responsibility at the same time. The Antarctic Treaty includes a protocol on environmental protection, which designates the continent as a natural reserve. There is a set of rules any visitor has to follow.
What is forbidden in Antarctica?
However, in Antarctica, taking anything is banned. This includes rocks, feathers, bones, eggs and any kind of biological material including traces of soil. Taking anything man-made is also completely banned, as some might actually be research equipment.

Could there be dinosaurs frozen in Antarctica?
Today, the continent of Antarctica holds the evidence of that ancient world, frozen beneath its ice and snow. As the climate changes again, melting Antarctic ice is allowing scientists to discover the remains of the past—including the fossils of those distinctive dinosaurs like Cryolophosaurus and Glacialisaurus.
Why do planes not fly over Antarctica?
Antarctica has no flight paths due to weather conditions and no infrastructure to assist with landing anywhere on the continent.
Can you smoke cigarettes in Antarctica?
However, if you're smoker, there's an extra rule: you have to collect every bit of ash you make. Even in Antarctica, you can only smoke in designated areas and then you have to carry all that ash until you leave Antarctica and can safely deposit it (this also counts for any litter you make).

Researchers in Antarctica have discovered in recent years hundreds of interconnected liquid lakes and rivers cradled within the ice itself. But this is the first time the presence of large amounts of liquid water in below-ice sediments has been found.
Is anyone 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.

The short answer is no, your mobile phone will not work during your tour of Antarctica. While we've come a long way from the earliest expeditions when explorers could only send snail mail via other ships, Antarctica is still a remote and wild destination with a telecommunications system to match.
How many years will it take for Antarctica to melt?
If the ice sheet were to melt completely–a process that could take as little as 500 years according to some models–global sea levels could rise by as much as 20 feet, inundating islands and coastal areas worldwide. The debate over whether the ice sheet is at risk hinges partly on its past history.
What happens if you get pregnant in Antarctica?
In the Antarctic and Arctic this must again rise probably to about 10%, higher in the field. With severe complications it could be up to 50% mortality. Risk: In a young woman the other risks of pregnancy include high blood pressure, pre-eclampsia, eclampsia, and haemorrhage.
Can you legally 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.
