Notes:
The dead sea is the sea with highest salinity. It has a salinity of 342 g/kg, or 34.2% it is one of the world’s saltiest bodies of water. The average salt concentration of of Dead Sea around 34% is much higher compared to an average of 3.5% for the world’s oceans. This high level of salinity is due to the fact that the Dead Sea is a saltwater lake that has no outlet, so the water is unable to flow out and dissipate its salt content. Instead, the salt remains in the water, leading to a very high concentration of minerals and other dissolved substances. The high salinity of the Dead Sea also makes it extremely buoyant, allowing people to float easily on its surface.
