Many things, large and small, are swallowed up by the oceans. At their bottom you can find wreckage of yachts, cargo and passenger steamers, warships, airplanes, helicopters, gold bars and even champagne, bottled 200 years ago.
But not only man-made things are drowning in the oceans. Fields, mountains, rivers and even entire continents, such as Atlantis, for example, disappear in them. Until recently, its existence belonged more to the realm of mythology, but in 2011, a company commissioned by oilmen to survey a section of the Atlantic Ocean floor using echo sounders made a sensational discovery. There was dry land to the west of the Shetland Islands several tens of millions of years ago.
The ancient landscape was discovered two kilometers below the sea floor. Scientists have managed to make a map of the prehistoric land. Territory on an area of 10 thousand square meters. km. included the channels of eight large rivers. With the help of drilling, it was possible to take samples of the rock in which coal and pollen residues were found. After which it became clear that there was once life on the covered two-kilometer-thick bottom of the earth. Scientists have suggested that even before the appearance of man, the land in this place was a single whole with the territories of today's Great Britain and continued until Norway.
By the way, under this layer again there were signs of only marine life. This means that this area once turned from the seabed to land, and then sank again under water. According to geological standards, this happened in a short time - for about two and a half million years.
To answer the question of why such things happened in the North Atlantic, the Icelandic plume theory was put forward. The fact is that the chemical composition of the stones raised from the bottom around Iceland indicates that magma was ejected from the depths of the earth in these places. Scientists have suggested that due to the very high temperatures and pressure of magma from below, part of the seabed rises above the water. Then, when this process is completed, she again plunges into the abyss. Of course, the landscape found in the North Atlantic was dry land even before the appearance of man on earth and is hardly the same Atlantis. But, perhaps, an answer has been found to the question of why she sank.
