The Dead Sea is a salt lake bordered by Jordan to the east and Israel and the West Bank to the west. It is the lowest lake on Earth, sitting 430.5 meters (1,412 feet) below sea level. The Dead Sea is also the saltiest lake in the world, with a salinity of 34.2%. This means that it is 8.6 times saltier than the ocean. The high salinity of the Dead Sea makes it difficult for plants and animals to live in, hence the name “Dead Sea.” However, the high salinity also makes the Dead Sea a popular tourist destination, as people can float easily in its waters.
