Mediterranean Sea
Mediterranean Sea is an in-land sea of Europe, Asia, and Africa, linked to the Atlantic Ocean at its western end by the narrow Strait of Gibraltar. The Mediterranean is almost landlocked. It is of great political and commercial importance as a maritime outlet and trade route for numerous countries. The Mediterranean Sea covers an area of about 2,510,000 sq km and is generally shallow. It is a remnant of a vast ancient sea that was squeezed almost shut about 30 million years ago, when Africa and Eurasia collided. Geological forces still cause volcanic eruptions and frequent earthquakes. An undersea sill at the Strait of Gibraltar restricts circulation, making the Mediterranean much saltier than the Atlantic Ocean. Arms of the Mediterranean include the Tyrrhenian, Adriatic, Aegean, and Ionian seas. Sicily, Sardinia, Corsica, Crete, and Cyprus are major islands. Barcelona, Marseille, Genoa, Trieste, and Haifa are important sea ports. Major rivers entering the Mediterranean are the Ebro, Rhone, Po, and Nile.
Black Sea
Black Sea is an in-land sea, lying between southeastern Europe and Asia Minor. It is connected with the Aegean Sea by the Bosporus, the Sea of Marmara, and the Dardanelles. The Black Sea is bounded by Romania, Bulgaria, Turkey, Ukraine, Russia, and Georgia. The Black Sea has an area (excluding its northern arm, the Sea of Azov) of about 436,400 sq km. The Crimean Peninsula projects into the Black Sea from the north, forming the shallow Sea of Azov on the east and the Karkinitskiy Gulf on the west. The Black Sea receives the drainage from central and eastern Europe, European Russia, the western Caucasus region, and northern Asia Minor.
The Black Sea is abundantly stocked with valuable fish. As an outlet for the products of Ukraine and adjoining republics, it is of special importance in regional commerce. Many of the colonial and commercial activities of ancient Greece and Rome, and of the Byzantine Empire, centered on the Black Sea. After 1453, when the Ottomans occupied Constantinople (present-day Istanbul), the sea was virtually closed to foreign commerce. The Treaty of Paris of 1856 opened the sea to the commerce of all nations.
Caspian Sea
Caspian Sea is a saltwater lake in southeastern Europe and southwestern Asia, the largest inland body of water in the world. The Caspian Sea is bordered on the west by Azerbaijan and Russia and on the south by Iran. It has an area of 371,000 sq km. The Caspian Sea is about 28 m below sea level, although this level changes from year to year.
The southern and southwestern shorelines of the Caspian Sea are bordered by the Elburz Mountains and the Caucasus Mountains. The seas" numerous tributaries include the Volga, Ural, and Zhem rivers. The Caspian Sea is linked to the Baltic Sea, the White Sea, and the Black Sea by an extensive network of inland waterways, chief of which is the Volga River. These waterways provide an outlet to northern Europe for the oil fields of Baku, Azerbaijan.
Navigation is frequently dangerous because of violent storms in the southeastern part of the Caspian Sea, and during the winter months the northern parts are closed by ice. The chief ports are Krasnovodsk, Turkmenistan; Baku; and Makhachkala, Russia.
