This is a very common misconception. Penguins live exclusively in the Southern Hemisphere – in the coastal waters of the Antarctic, Australia, New Zealand, South Africa and South America.
Right you are. The Arctic also includes the northern outskirts of Eurasia and North America, almost the entire Arctic Ocean, and the adjacent areas of the Atlantic and Pacific oceans.
Not quite so. It is widely accepted that besides the North Pole and its surrounding ice, the Arctic includes the northern territories of Eurasia and North America, almost the entire Arctic Ocean, and the adjacent areas of the Atlantic and Pacific oceans.
Scientists, however, are confident that Artic volcanoes are not a myth! They managed to register underground shocks that are evidence of volcanic activity.
There are active volcanoes on the bottom of the Arctic Ocean. In 1999, a series of powerful underground shocks were registered in the area of the mid-oceanic Gakkel Ridge in the eastern part of the Arctic.
The so-called dead water effect occurs where a layer of fresh water rests on a denser layer of salt water. As a result, the rotational energy from a ship’s screws goes towards forming waves between the layers instead of moving forward.
Wrong! Norwegian polar explorer Fridtjof Nansen was the first person to describe the dead water phenomenon in 1893 after his ship, Fram, got stuck in such a zone.
Not quite so. Although the sun stays below the horizon during the polar night period, that doesn’t necessarily mean complete darkness for 24 hours. Most of the regions experience polar twilight along with polar nights.
Right you are. A polar night does not necessarily mean complete round-the-clock darkness. In some regions, twilight occurs during part of the polar night.
If this were true, how would numerous animal species live there? The Arctic experiences extremely cold weather only in the winter, when the average temperature reaches minus 36 degrees Celsius. The average summer temperature is about 0 degrees.
That’s not true! As a rule, ice is far less salty than the water which forms it. When water freezes, the salt gets squeezed out. On average, the salinity of ice is four times lower than the salinity of the water from which it was formed.
