The Dead Sea is a salt lake bordered by Jordan to the east and Israel and the West Bank to the west. It lies in the Jordan Rift Valley, and its main tributary is the Jordan River. Its surface and shores are 430.5 metres below sea level, Earth’s lowest elevation on land.

Why do they call it the Dead Sea :

The sea is called “dead” because its high salinity prevents macroscopic aquatic organisms, such as fish and aquatic plants, from living in it, though minuscule quantities of bacteria and microbial fungi are present. In times of flood, the salt content of the Dead Sea can drop from its usual 35% to 30% or lower.

What is special about Dead Sea :

1. The Dead Sea is one of the saltiest bodies of water on Earth, with almost 10 times more salt than ordinary seawater. This is because water flows into the Dead Sea from one main tributary, the River Jordan. … The high salt and mineral content of the Dead Sea mean that this body of water has powerful healing properties.

Is it safe to swim in the Dead Sea :

In actuality, it is nearly impossible to swim in the Dead Sea. Because of the high salt content of the water, people who bathe in the Dead Sea can actually float on the surface of the water. … The only living beings that reside in the dead sea are bacteria and an especially hardy species of algae.

Salt deposits

The Sedom Lagoon deposited evaporites mainly consisting of rock salt, which eventually reached a thickness of 2.3 km (1.43 mi) on the old basin floor in the area of today’s Mount Sedom.

Sedom Lagoon ;

During the late Pliocene-early Pleistocene, around 3.7 million years ago,[citation needed] what is now the valley of the Jordan River, Dead Sea, and the northern Wadi Arabah was repeatedly inundated by waters from the Mediterranean Sea. The waters formed in a narrow, crooked bay that is called by geologists the Sedom Lagoon, which was connected to the sea through what is now the Jezreel Valley.[citation needed] The floods of the valley came and went depending on long-scale changes in the tectonic and climatic conditions.

Recession and environmental concerns :

Since 1930, when its surface was 1,050 km2 (410 sq mi) and its level was 390 m (1,280 ft) below sea level, the Dead Sea has been monitored continuously. In recent decades, the Dead Sea has been rapidly shrinking because of diversion of incoming water from the Jordan River to the north
