What is the Meaning & Definition of Black Sea

The Black Sea is one of the seas that is located in the northern hemisphere, more specifically between Europe and Asia. This sea acts just as a division between the two continents and bathes the coasts of countries such as Ukraine, Russia, Georgia, Romania, Bulgaria and Turkey, as well as of the famous cities of Odessa, Istanbul, Yalta and Sevastopol. The Black Sea is an inner sea which is only connected by small steps with the Mediterranean (through the Bosphorous Strait, first with the sea of Marmara and then to the Aegean Sea through the Straits of the Dardanelles). The Black Sea has more than four hundred thousand square kilometers and a maximum depth of two thousand two hundred meters. In its interior boasts more than ten islands among which we can mention the St. Cyricus Island, Berezan, Santa Anastasia, St. Ivan and St. Thomas. The formation of the Black Sea has to do with the separation of two basins from a volcanic effect. At the same time, tectonic movement provided the area with numerous mountain ranges that marked the biggest difference between the water level and its depth, transforming this course of water from a Lake to a sea. The Black Sea is known worldwide for its high proportion of salt water, provienente mainly of the Bosphorus Strait, while the Danube River also adds fresh water due to its tributary. This combination of two different types of water may make the Black Sea a sea not mixing different layers of water and therefore the surface differs from the rest of the world's oceans. This phenomenon is known as meromictic phenomenon and generated that the surface layers are lighter due to the constant action of the rivers, while the lower become more dense and heavy for its high in salt. The Black Sea is one of the most important tourist places of the region, having numerous cities that have beautiful and luxurious beaches. In addition, they make most of the tourists that come to this area, to experience the phenomenon mentioned meromictic.
