Dead Sea hypothesis is that the Dead Sea lies in a true rift zone, an extension of the Red Sea Rift, or even of the Great Rift Valley of eastern Africa. A more recent hypothesis is that the Dead Sea basin is a consequence of a "step-over" discontinuity along the Dead Sea Transform, creating an extension of the crust with consequent subsidence.

Dead Sea Dead Sea The Dead Sea ( lit. Sea of Salt; ) is a salt lake bordered by Jordan to the east and Israel and the West Bank to the west. Its surface and shores are below sea level, Earth's lowest elevation on land. The Dead Sea is deep, the deepest hypersaline lake in the world. With a salinity of 342 g/kg, or 34.2% (in 2011), it is 9.6 times as salty as the ocean and one of the world's saltiest bodies of water. This salinity makes for a harsh environment in which plants and animals cannot flourish, hence its name.
