The Dead Sea is called "Dead" because its water contains an extremely high concentration of salt and minerals, making it one of the saltiest bodies of water on Earth. With a salinity of about 34%, it is nearly ten times saltier than the ocean, creating conditions in which fish, aquatic plants, and most other forms of marine life cannot survive. The Dead Sea has no outlet, so water flows into it mainly from the Jordan River but leaves only through evaporation, causing salts and minerals to become highly concentrated over time. Located about 430 meters (1,410 feet) below sea level, it is also the lowest exposed land elevation on Earth. In the Bible, the Dead Sea region is closely associated with the destruction of Sodom and Gomorrah (Genesis 19) and later became famous for the discovery of the Dead Sea Scrolls near Qumran in 1947, making it one of the most remarkable geographical locations in biblical history.
