Why is the Dead Sea so salty?

Why is the Dead Sea so salty? Some parts of the ocean are more saline than others, particularly where there are higher levels of evaporation, such as in the Red Sea. Isolated bodies of water can also become extra salty, or hypersaline, through evaporation. The Dead Sea in the Middle East is an example of this.

What is the Black Sea famous for?

The Black Sea is the world's largest body of water with a meromictic basin. The deep waters do not mix with the upper layers of water that receive oxygen from the atmosphere. As a result, over 90% of the deeper Black Sea volume is anoxic water.

What is the difference between the sea and the ocean?
