What is the Dead Sea? Detailed answer Directory / Big encyclopedia. Questions for quiz and self-education Did you know? What is the Dead Sea? The Dead Sea is a truly strange and, moreover, far from the only name given by man to this one of the most unusual reservoirs on Earth. For the first time this sea began to be called "dead" by the ancient Greeks. The inhabitants of ancient Judea called him "salty". Arabic authors referred to it as "the stinking sea". What is the peculiarity of this sea? In reality, it is rather a huge salt lake located between Jordan and Israel. It is formed in a depression or crack in the earth's crust that exists in this region. The Dead Sea stretches for about 75 km in length, reaching a width in various places from 5 to 18 km.
Surprising is the fact that the surface of the Dead Sea is 400 m below the level of the oceans. In its southern part, its depth is small, but in the northern part it reaches 400 m. Unlike ordinary lakes, not a single river flows out of the Dead Sea, but it itself absorbs the waters of the Jordan River, which flows into it from the north, and many small streams flowing from the slopes of the surrounding hills. The only way excess water is removed from the sea is by evaporation. As a result, an unusually high concentration of mineral salts was created in its waters, such as table salt, potassium carbonate (potash), magnesium chloride and bromide, and others. Therefore, the Dead Sea is the saltiest sea in the world. The concentration of salts in its water is 6 times higher than in the ocean! This increases the density of the water so much that a person floats here like a cork without any effort! The Dead Sea can serve as a huge source of valuable substances. According to scientists, about 2 tons of potash are dissolved in it, which is used to produce fertilizers for the soil. Author: Likum A. Random interesting fact from the Great Encyclopedia: What did the philosopher Auguste Comte consider the most striking example of such knowledge, which will forever remain hidden from man, and why was he wrong? In 1844, the philosopher Auguste Comte (1798-1857) was looking for an example of such knowledge that would forever remain hidden from mankind. He focused on the chemical composition of distant stars and planets. Comte believed that a person would never visit them and, having no samples of a substance in his hands, was forever deprived of the opportunity to know its composition. Auguste Comte chose an extremely unfortunate example. Just three years after his death, it became clear that the spectrum of their radiation could be used to determine the chemical composition of distant objects. Astronomical spectroscopy made it possible to determine the composition of the gas shells of the planets of the solar system, the chemical composition of the Sun, distant stars and galaxies.
