Which salty body of water is the lowest land elevation on Earth?

The Dead Sea is recognized as the lowest land elevation on Earth, lying at approximately 430 meters (1,411 feet) below sea level. This unique geographical feature is a result of tectonic movements in the Jordan Rift Valley, where the Earth's crust has subsided. The high salinity of the Dead Sea, around ten times saltier than most oceans, is due to high evaporation rates in this arid climate, which cause minerals to accumulate in the water. In contrast, while Lake Urmia, the Great Salt Lake, and the Caspian Sea also contain saline water, they are not positioned at the same extreme low elevation as the Dead Sea. Lake Urmia, for instance, is significantly higher in elevation, as are the other two bodies of water. The Caspian Sea, despite being the largest enclosed inland body of water, does not reach the same low point as the Dead Sea. Therefore, the Dead Sea stands out as the saltiest body of water at the lowest elevation on Earth's surface.
