The Dead Sea has shores that mark the lowest land elevation on Earth. This landlocked salt lake lies in the Jordan Rift Valley, bordered by Jordan to the east and Israel and the West Bank to the west.
Its surface sits hundreds of metres below mean sea level and continues to fall as inflows from the Jordan River have been greatly reduced and evaporation remains intense. The lake is endorheic, meaning it has no outlet; water leaves primarily through evaporation, concentrating salts and minerals in the remaining water.
The Dead Sea is famous for its buoyant, hypersaline water, but it is not the deepest point on Earth—that distinction belongs to ocean trenches such as Challenger Deep. Nor is it the lowest exposed bedrock: the question refers to the lowest land elevation associated with a shoreline. The nearby Sea of Galilee and Caspian Sea also lie below sea level, but neither reaches the Dead Sea's elevation.
