The Dea Sea (Arabic: البَحْر المَيّت, al-Baḥrᵘ l-Mayyitᵘ, "Dead Sea";Hebrew: יָם הַמֶּלַח, Yām Ha-Melaḥ, "Sea of Salt") is a salt lake between Israel (and the West Bank) to the west, and Jordan to the east. It is 420 metres (1,378 ft) below sea level, and its shores are the lowest point on the surface of the Earth on dry land. The Dead Sea is 330 m (1,083 ft) deep, the deepest hypersaline lake in the world. It is also the world's second saltiest body of water, after Lake Asal in Djibouti, with 30 percent salinity. It is 8.6 times saltier than the ocean. Israeli experts say that it is nine times saltier than the Mediterranean Sea (31.5% salt versus 3.5% for the Mediterranean). The Dead Sea is 67 kilometres (42 mi) long and 18 kilometres (11 mi) wide at its widest point. It lies in the Jordan Rift Valley, and its main tributary is the Jordan River.
