Antarctica is the coldest, driest, windiest continent in the world. It’s colder than the North Pole and other continents. The warmest temperature ever recorded in Antarctica was 59 degrees Celsius and the coldest was -192 degrees Celsius.
Temperature’s in Antarctica vary greatly, from Summer to Winter. Six months of broad daylight is Summer. And the other six months is full darkness of winter.
Antarctica is covered in a thick layer of ice.
This ice slowly moves away from the continent, then brakes into glaciers during winter.
A giant iceberg can be more than 1 million
Tons. In 1987 there was and iceberg 3 times bigger than Rhode island.
Glaciers grew millions of years ago in the South Pole. They cover most of Antarctica and supplies 70% of the worlds fresh water.
Glaciers have different sizes, locations and shapes. The biggest glacier in the world is 210 000 tons. Scientist’s call it an ice cap.
The Antarctic ice sheet flows continually outward from the centre of the continent
towards the ocean. It slides forward to the ocean to form ice shelves. It also frequently
and gradually slopes.
Antarctica has lots of answers and questions that scientist’s can’t answer like … why the water doesn’t freeze? And why the plants don’t freeze either? These sort of questions are still trying to be answered by scientist’s all over the world.
