largest lake in the world - the Caspian Sea.It is located on the border of Europe and Asia, and washes the shores of five states: Russia, Kazakhstan, Turkmenistan, Iran and Azerbaijan.Title Sea lake was due to its impressive size.The Caspian Sea - a closed lake with salt water.The shape of the Caspian Sea resembles the Latin letter S. Slowness of the lake from north to south is about 1,200 km from west to east 195 - 435 km and the average is 310 - 320 km.
On physical and geographical criteria Caspian Sea is divided into three conditional parts: No
rth, Central, South Caspian Sea, covering an area of ​​25, 36, 39% respectively of the total area of ​​the lake.
coastline of the Caspian Sea has a length of about 6500 - 6700 km, and from the islands up to 7000 km.Caspian coast is mainly low-lying and smooth.On the east coast is dominated by limestone, which are adjacent to the deserts and semi-deserts.On the west (near the Apsheron Peninsula) and the east (near the Kazakh Bay and the Kara-Bogaz-Gol) coasts more meandering coast.Middle Caspian coast is indented islands and water channels of the Volga and the Urals.The banks are low and boggy, in some parts of the water surface dense thickets grow.The coastal part of the Caspian Sea is called the Caspian Sea region.
reservoir area and volume of water in the Caspian Sea vary depending on changes in the water level.Thus, when the water level of 26.75 m surface area is approximately 371,000 km2, and the amount - 78 648 km3, which is equal to approximately 44% of the world's supply of the lake waters.The value of the maximum depth of the Caspian Sea is 1,025 meters above the surface, and is achieved in the South Caspian Basin.Under this option the Caspian Sea is second only to Lake Tanganyika (1435 m) and Baikal (1640 m).the average depth of the Caspian Sea is 208 m. The most shallow is the northern part of the Caspian Sea, since its maximum depth is 25 m, with an average depth of 4 m.
