Dead Sea

The Dead Sea, also known by other names, is a landlocked salt lake bordered by Jordan to the east and the Israeli-occupied West Bank and Israel to the west. It lies in the Jordan Rift Valley, and its main tributary is the Jordan River.

As of 2019, the lake's surface is 430.5 metres below sea level, making its shores the lowest land-based elevation on Earth. It is 304 m deep, the deepest hypersaline lake in the world. With a salinity of 342 g/kg, or 34.2%, it is one of the world's saltiest bodies of water – 9.6 times as salty as the ocean – and has a density of 1.24 kg/litre, which makes swimming similar to floating.
