Ninety-eight percent of the continent is covered with an ice sheet, and the soil is frozen under it.
They did not have to. Walruses do not live in Antarctica.
Cold.
Since 98% of the continent is covered by an ice sheet, it is difficult to see 'cracks in the ground' in Antarctica. Otherwise, these would be known as canyons.
Sun rays are almost parallel to the surface at Antarctica.
No. Antarctica is too cold to support any kind of food chain.
Yes, Antarctica is known as the snowiest place on Earth. It receives very little precipitation in the form of rain, but snowfall can be abundant due to the cold temperatures and the continent's unique climate conditions.
Yes, there is sand in Antarctica, but it is not as common as in other regions due to the icy conditions and limited vegetation.
Some equipment is sent to Antarctica to be tested, because there are some environments in Antarctica that mimic other planets and extreme conditions.
Explorers brought food with them to Antarctica. One staple is pemmican: a mix of 50% ground meat and 50% lard.
Antarctica is the continent with the least amount of forest cover. Its harsh climate and icy conditions do not support the growth of forests.
Antarctica is the coldest place on earth because the sun's rays hardly reach there.
Due to the very harsh conditions (it's very cold there) and the little things you can do in Antarctica, not many tourists go there.
