Q. What biome is most of Antarctica?
Antarctic tundra occurs on Antarctica and on several Antarctic and subantarctic islands, including South Georgia and the South Sandwich Islands and the Kerguelen Islands. Most of Antarctica is too cold and dry to support vegetation, and most of the continent is covered by ice fields.
Q. Is Antarctica tundra or desert?
While Antarctica is classified as a desert, many of the nearby islands are considered tundra, including the South Shetland Islands, South Georgia and the Falkland Islands.

Q. Is Antarctica the hottest place on earth?
Antarctica is the coldest place on earth. It is also the windiest, driest, and highest continent. The South Pole is not the coldest place in Antarctica. The coldest temperature recorded in Antarctica was -89.6°C at Vostok station in 1983.
Q. What triggers an ice age?
An ice age is triggered when summer temperatures in the northern hemisphere fail to rise above freezing for years. The onset of an ice age is related to the Milankovitch cycles – where regular changes in the Earth’s tilt and orbit combine to affect which areas on Earth get more or less solar radiation.
Q. Were there humans in the ice age?
The analysis showed there were humans in North America before, during and immediately after the peak of the last Ice Age. This significant expansion of humans during a warmer period seems to have played a role in the dramatic demise of large megafauna, including types of camels, horses and mammoths.

Q. How warm was the earth before the ice age?
The average global temperature during the period known as the Last Glacial Maximum from roughly 23,000 to 19,000 years ago was about 46 degrees Fahrenheit (7.8 degrees Celsius), some 13 degrees Fahrenheit (7 Celsius) colder than 2019, the researchers said on Wednesday.
Q. When was there no ice on Earth?
Summary: For years, scientists have thought that a continental ice sheet formed during the Late Cretaceous Period more than 90 million years ago when the climate was much warmer than it is today. Now, researchers have found evidence suggesting that no ice sheet formed at this time.
Q. What was the world like before the ice age?
A true Hothouse Earth emerged when carbon dioxide levels reached something like 800ppm – about double those of today. This was the world of the dinosaurs, 100m years ago. There was little or no ice on Earth and the polar regions had forests and dinosaurs which were adapted to living half the year in darkness.
