At the bottom of the Dead Sea there are deposits of natural asphalt, and the water here is so dense that asphalt, floating up from the bottom in whole blocks, floats on the surface. Because of this, in ancient Greece this unique body of water was even called the Asphaltite Sea! True, these deposits have obviously been depleted, and no one has seen asphalt here for a long time.
Only the Jordan and Mujib rivers flow into the Dead Sea, as well as several streams that often dry up. In general, it may soon disappear, since over the past 100 years the volume of water entering it annually has decreased by 14 times, from 1.43 billion cubic meters to 100 million cubic meters.
Strictly speaking, the Dead Sea is only called the sea, in fact it is just a large drainless lake. Relatively large - its area is approximately 810 km², which is slightly smaller than the area of Moscow inside the Moscow Ring Road. For comparison, the area of Lake Baikal is ten times larger, as much as 31.722 km².
The Dead Sea is the lowest land area on Earth. It lies 430 meters below sea level, so the atmospheric pressure here is slightly higher than usual, and the level of solar radiation is minimal.
The salinity level here exceeds the average for the seas and oceans by 7-9 times. For example, in the Mediterranean Sea it is about 40 ppm, and in the Dead Sea it ranges from 270 to 310 ppm.
