The Black Sea is an inland sea bounded by Europe, Anatolia and the Caucasus and is ultimately connected to the Atlantic Ocean via the Mediterranean and Aegean Seas and various straits. The Bosphorus strait connects it to the Sea of Marmara, and the strait of the Dardanelles connects it to the Aegean Sea region of the Mediterranean. These waters separate eastern Europe and western Asia. The Black Sea also connects to the Sea of Azov by the Strait of Kerch.

The Black Sea has an area of 436,400 km2 (168,495.0 sq mi), a maximum depth of 2,206 m (7,238 ft), and a volume of 547,000 km³ (133,500 cu mi). The Black Sea forms in an east-west trending elliptical depression which lies between Bulgaria, Georgia, Romania, Russia, Turkey, and Ukraine. It is constrained by the Pontic Mountains to the south, the Caucasus Mountains to the east and features a wide shelf to the north-west. The longest east-west extent is about 1,175 km.

Important cities along the coast include Batumi, Burgas, Constanţa, Giresun, Istanbul, Kerch, Kherson, Mangalia, Năvodari, Novorossiysk, Odessa, Ordu, Poti, Rize, Samsun, Sevastopol, Sochi, Sukhumi, Trabzon, Varna, Yalta and Zonguldak.

The Black Sea has a positive water balance, which results in a net outflow of water 300 km³ per year through the Bosphorus and the Dardanelles into the Aegean Sea (part of the Mediterranean Sea). Mediterranean water flows into the Black Sea as part of a 2-way hydrological exchange. The Black Sea outflow is cooler and less saline , and therefore floats over the warm, more saline Mediterranean inflow. The Black Sea also receives river water from large Eurasian fluvial systems to the north of the Sea, of which the Don, Dnieper and Danube are the most significant.

In the past, the water level has varied significantly. Depending on the water level in the basin, varying surrounding shelf and associated aprons are aerially exposed. At certain critical depths, it is possible for connections with surrounding water bodies to become established. It is through the most active of these connective routes, the Turkish Straits, that the Black Sea joins the global ocean system. When this hydrological link is not present, the Black Sea is a lake, operating independently of the global ocean system. Currently the Black Sea water level is relatively high, thus water is being exchanged with the Mediterranean. The Turkish Straits connect the Black and Aegean Seas and comprise the Bosphorus, the Sea of Marmara and the Dardanelles.

  • @rosskay there are other species of animals unique to the area, including a type of iridescent lizard and a bird that lives with it symbiotically. It think both might be from africa, but im not sure. anyone who knows the names of these lizards, would love to know. been looking for it's name for a while now, never seen or heard it of anywhere else.

  • I never liked lakes they always creeped me out, and the black sea always irked me so there you go. Lake ancestry. don't know if the scientists know or realize this... but the same flooding around the pannonian plains would have caused the the black sea to become a sea. There is a small preserved area in serbia where there is still sand from this once covered by water, there are multiple snail species that live on the tall grases that evolved from being water snails, its an amazing sight to see.

  • @sega31098 and?

  • Can it be Atlantis buried under black sea ? and the flood is "Noah Flood" (since date about it is similar) wow, we need deep sea exploration in "Black Lake" :D

  • bekar video

    

  • According to Josephus, the Armenians in the 1st century showed the remains of Noah's ark at a place called αποβατηριον "Place of Descent" (Armenian: Նախիջեւան, Nakhichevan, Ptolemy's Ναξουανα), about 60 miles southeast of the summit of Mount Ararat (ca. 39.07°N 45.08°E).[3] Josephus also stated that Themanin, the first city to be built after the Great Flood, was built at the base of Mount Judi.[4] (wiki).

  • The Black Sea still expands because of the strong streams and rivers that's the cause of and the place (i think) of noah's flood.
