Located on the border between Israel and Jordan, the Dead Sea is one of the most intriguing natural phenomena on Earth. Aside from some microorganisms and algae, this saltwater lake is completely devoid of life. There’s no seaweed, fish, or any other creatures found in or around its turquoise waters.

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 the water flows into the Dead Sea from one main tributary, the River Jordan. It then has no way to get out of the lake and so is forced to evaporate.

The soaring hot and dry conditions of this region mean that large quantities of water are evaporated. This leads to the salt and other minerals becoming more and more concentrated. In fact, it’s estimated that in the whole of the Dead Sea there is about 37 billion tonnes of salt.
