Great Flood

The Black Sea is one of the most characteristic seas on the globe. As a result of the geological structure of the reservoir, a two-level water system was created . On the one hand, great rivers flow into the Black Sea (m.in. Dnieper, Dniester and Danube), and on the other, the salty waters of the Mediterranean Sea. Because fresh water is lighter than saline water, low salinity will remain on the surface, while below 250 m salt concentration is unbearable for living organisms. They are there, except salt, hydrogen sulfide and various poisonous minerals. Fresh water floating on the surface additionally blocks the flow of oxygen to the lower parts, so only bacteria can live there, not needing this gas to exist. Through the Bosphorus, the Sea of ​​Marmara and the Dardanelles, the movement of the water is in both directions – excess freshwater from the Black Sea flows into the Mediterranean Sea, and the bottom, heavy flows in the opposite direction, salt water from the Mediterranean Sea.

Relatively recently, because w 1999 r., a group of scientists from the United States announced a sensational discovery, that 7500 years ago there was a great flood in the Black Sea basin, which can be a confirmation of Noah's biblical story. To the Black Sea, at that time a freshwater lake, tribes came from all over Asia Minor, as a result of climate change, more specifically – the onset of a period of drought and cold. As a result of melting glaciers, the water level of all seas began to rise systematically. The seas so far separated: Mediterranean and Black, were connected after water poured into a tectonic ditch, that is, today's Dardanelles, Sea of ​​Marmara and Bosphorus. Because the lake was lower, the sudden rush of water created a gigantic waterfall at the mouth of today's Bosphorus, and the water swiftly flooded the densely populated shores of the lake. The catastrophe was so great, that her footprint was to survive in the stories and was crowned with the parable of Noah's ark.

Other scientists responded to these revelations, this time in a wider group (m.in. You have, Great Britain and the United States), announced a new one, a different theory. According to them, and they had strong evidence to support their thesis from seismic profile measurements and other methods, it was not the Mediterranean that poured into the Black Sea, but vice versa. Besides, it was not a flood, but a smooth flow. The great rivers brought so much water over time (much faster, than the melting glaciers supplied the Mediterranean Sea), that it overflowed a natural dam and proceeded towards the Sea of ​​Marmara.
