The Black Sea

Do you hear about the beautiful Black Sea?Do you like what you see?Do you like this pictures?

If you like what you see, come in my beautiful country Romania.We have here many fun park, many shops, clubbing/clubbing on the beach , a BIG beach just for you to enjoy the beautiful life.

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 Bosporus 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),[1] a maximum depth of 2,206 m (7,238 ft),[2] and a volume of 547,000 km³ (133,500 cu mi).[3] The Black Sea forms in an east-west trending elliptical depression which lies between Bulgaria, Georgia, Romania, Russia, Turkey, and Ukraine.[4] 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 (alphabetical order) : Batumi (121,806), Burgas (229,250),Constanţa (306,000 with a metropolitan area of 550,000), Giresun (90,034),Istanbul (11,372,613), Kerch (158,165), Kherson (358,000), Mangalia (41,153),Năvodari (34,669), Novorossiysk (281,400), Odessa (1,001,000), Ordu (190,143), Poti (47,149), Rize (91,901), Samsun (439,000), Sevastopol (379,200), Sochi (328,809), Sukhumi (43,700), Trabzon (275,137), Varna (357,752), Yalta (80,552), and Zonguldak (104,276) .

The Black Sea has a positive water balance, which results in a net outflow of water 300 km³ per year through the Bosphorus 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 less saline and cool, 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.
