The reason why the Dead Sea allows people to float is because of the high concentration of salt water. The salt content of the Dead Sea is extremely high, and it gets higher as you reach the bottom of the lake. It is 10 times more salty than the ordinary ocean. The lake water in the deepest part has been fossilized (generally, the salt content of sea water is 3.5, while the salt content of the Dead Sea is 23 to 25. The salt content in the surface water reaches 227 to 275 grams per liter, and the salt content in the deep water reaches 327 grams).
The Dead Sea is located at the lowest point of Jordan-Palestine-Israel (560 kilometers [350 miles] long) and is the northern continuation of the East African Rift Valley. This is a piece of sinking crust sandwiched between two parallel geological fault scarps. The lake elevation is -430.5 meters. The deepest point of the lake is 380.29 meters, and the altitude of the deepest lake bed is -800.112 meters. It is also the third saltiest body of water on Earth, behind Don Juan Pond in Antarctica, which is the second saltiest, and Gaet'ale Pond in Ethiopia, which is the first.
The Dead Sea is located in the Jordan Rift Valley, the Great Rift Valley between Israel, Palestine and Jordan. It is 86 kilometers long from north to south, 5 to 16 kilometers wide from east to west, and the deepest point is 380.29 meters. The shores of the Dead Sea are the lowest point on earth that has exposed land, and are known as the "navel of the world." From a distance, the Dead Sea looks like a two-tailed fish. Under the sunlight, the sea surface looks like an ancient bronze mirror. After the 1967 Israeli-Arab War, Israeli forces occupied the entire West Bank. The Dead Sea contains a high concentration of salt, causing no living things to survive in the water. Even the land along the Dead Sea has very few living things except aquatic plants. This is one of the reasons why people named it the Dead Sea.

The salt content in the surface water reaches 227 to 275 grams per liter, and the salt content in the deep water reaches 327 grams). Because of its high concentration, salt water can make people float. There are no other animals or plants in the lake except bacteria. Fish swimming from the Jordan or other small rivers at high tide die immediately. Shore plants are also mainly halophytes adapted to saline-alkali soils. The Dead Sea is a large salt depository. The shores of the Dead Sea are deserted, with few fixed settlements and occasional small patches of cultivated land and health resorts.
