In ancient times, 65 million years ago (the end of the age of dinosaurs), on the border between the Cretaceous and Paleogene periods, lapped the ancient Tethys ocean . which, in geologically near future had to disappear and leave behind the Mediterranean . The black and Caspian seas and the Persian Gulf. The first two are further connected by the Atlantic ocean, the latest from the Indian.

The formation of the Strait of Gibraltar and the Mediterranean sea (5 million years BP)
The Strait of Gibraltar that separates Morocco from Spain, is only 15 km width. Perhaps the flooding of the plains by the ocean between Africa and Europe and is reflected in the ancient Greek myth of Debelyanovo the flood that supposedly happened in “ancient Greece”*, namely in the district of Dodon and of the river of Aheloy [I think it was near the Caucasus, and then we can talk about the Black sea]. There is another myth, that the rocks of Gibraltar and Ceuta opened Hercules.
The breakthrough of the Ocean through the Gibraltar – perhaps the work of man.

Black sea – an inland sea basin of the Atlantic ocean. The Bosporus connects to the sea of Marmara, then through the Dardanelles with the Aegean and Mediterranean seas. The Kerch Strait connects the sea of Azov. North sea cuts deeply into the Crimean Peninsula. On the surface Black sea water passes the border between Europe and Asia Minor.
A characteristic feature of the Black sea is complete (except for some anaerobic bacteria) absence of life at depths greater than 150-200 m due to the saturation of deep layers of water with hydrogen sulfide.
The climate of the Black sea, due to its mid-continental situation, mainly continental. The black sea coast of Caucasus and the southern coast of the Crimea being protected by mountains from cold Northern winds and as a consequence, have a mild Mediterranean climate and South-East of the Tuapse — humid subtropical climate. A significant impact on the weather over the Black sea has the Atlantic ocean, which originates most of the cyclones at sea bringing bad weather and storms. In the North-East coast, especially in the area of Novorossiysk, low mountains are not a barrier to cold Northern air masses, which, moving through them, cause a strong cold wind (Bora), the locals call it “Nord-OST”.South-westerly winds usually in the black sea region brought a warm and wet Mediterranean air mass. As a result, for the greater part of the territory sea is characterised by warm wet winters and hot dry summers.
The black sea fills the insulated cavity, located between Southeast Europe and Asia Minor. This depression was formed in the Miocene epoch, during an active orogeny that divided the ancient Tethys ocean into several separate water bodies (of which more later, except the Black sea, formed the Azov, Aral and Caspian seas).
