The Dead Sea, 417 m below sea level, is the lowest point on the surface of the earth. It is at the terminus of the Jordan River, has no outlet and is very rich in minerals. The dissolved material includes high concentrations of potassium, bromine and magnesium salts, which are commercially exploited. It has a salinity of 3,000 mg/l, over 40 times as salty as Mono Lake and is the world's saltiest large water body. Almost nothing can survive in this water except highly specialized green algae and red archaeobacteria which are of great scientific interest.

It has a surface area currently of 810 square kilometers, 1/3 smaller than its natural size. It has a depth of 330 meters.

The surface of the Dead Sea, 408 m (1,340 ft) below sea level as of 1996, is the lowest water surface on earth. The lake is 80 km (50 mi) long and has a maximum width of 18 km (11 mi); its area is 1,020 sq km (394 sq mi).

The Dead Sea is both the lowest point on Earth at 418 meters (1,371 ft) below sea level and falling[2], and the deepest hypersaline lake in the world at 330 meters (1,083 ft) deep and 799 meters (2,621 ft) below sea level. It is also one of the saltiest bodies of water on Earth with a salinity of about 300 ppt, This is about 8.6 times greater than the average ocean salinity. It measures 67 kilometers (42 mi) long, up to 18 kilometers (11 mi) wide, and is located on the border between the West Bank, Israel, and Jordan, and lies in the Jordan Rift Valley. The main tributary is the Jordan River.

The Dead Sea has attracted interest and visitors from around the Mediterranean basin for thousands of years. It was a place of refuge for King David, it was one of the world's first health resorts for Herod the Great, and it has been the supplier of products as diverse as balms for Egyptian mummification to potash for fertilizers.

In Hebrew the Dead Sea is called the Yam ha-Melakh - meaning "sea of salt", or Yam ha-Mavet - meaning "sea of death". In past times it was the "Eastern Sea" or the "Sea of Arava". In Arabic the Dead Sea is called Al Bahr al Mayyit meaning "the Dead Sea", or less commonly Bahr LÅ«Å£ meaning "the Sea of Lot". Historically, another Arabic name was the "Sea of Zoar", after a nearby town. To the Greeks, the Dead Sea was "Lake Asphaltites
Natural history

Satellite photograph showing the location of the Dead SeaThe Dead Sea is located in the Dead Sea Rift, which is part of a long fissure in the Earth's surface called the Great Rift Valley. The 6000 km (3700 mile) long Great Rift Valley extends from the Taurus Mountains of Turkey to the Zambezi Valley in southern Africa. The Great Rift Valley formed in Miocene times as a result of the Arabian Plate moving northward and then eastward away from the African Plate.

Around three million years ago what is now the valley of the Jordan River, Dead Sea, and Wadi Arabah/Nahal Arava was repeatedly inundated by waters from the Mediterranean Sea. The waters formed in a narrow, crooked bay which was connected to the sea through what is now the Jezreel Valley. The floods of the valley came and went depending on long scale climatic change. The lake that occupied the Dead Sea Rift, named "Lake Sodom", deposited beds of salt, eventually coming to be 3 km (2 miles) thick.

According to geological theory, approximately two million years ago the land between the Rift Valley and the Mediterranean Sea rose to such an extent that the ocean could no longer flood the area. Thus, the long bay became a long lake.

The first such prehistoric lake is named "Lake Gomorrah". Lake Gomorrah was a freshwater or brackish lake that extended at least 80 km (50 miles) south of the current southern end of the Dead Sea and 100 km (60 miles) north, well above the present Hula Depression. As the climate turned more arid, Lake Samra shrank and became saltier. The large, saltwater predecessor of the Dead Sea is called "Lake Lisan".

Mount Sedom, on the southwest side of the lake, is a giant mountain of halite.In prehistoric times great amounts of sediment collected on the floor of Lake Gomorra. The sediment was heavier than the salt deposits and squeezed the salt deposits upwards into what are now the Lisan Peninsula and Mount Sedom (on the southwest side of the lake). "Geologists explain the effect in terms of a bucket of mud into which a large flat stone is placed, forcing the mud to creep up the sides of the pail". When the floor of the Dead Sea dropped further due to tectonic forces the salt mounts of Lisan and Mount Sedom stayed in place as high cliffs. (see salt domes)

During 70,000 to 12,000 years ago the lake level was a 100-250 meters higher than its current level. This lake was termed "Lake Lisan", which fluctuated dramatically with rising to highest level around 26,000 years ago, indicating very wet climate in the Near East. Sometime around 10,000 years ago the lake level dropped dramatically, probably to levels even lower than today. During the last several thousand years the lake has fluctuated approximately 400 m with some significant drops and rises.

The Jordan River is the only major stream flowing into Dead Sea. There are no outlet streams.

The northern part of the Dead Sea receives scarcely 100 mm (4 inches) of rain a year. The southern section barely 50 mm (2 inches). The Dead Sea zone's aridity is due to the rainshadow effect of the Judean Hills. The highlands east of the Dead Sea receive more rainfall than the Dead Sea itself.

The mountains of the western side, the Judean Hills, rise less steeply from the Dead Sea than do the mountains of the eastern side. The mountains of the eastern side are also much higher. Along the southwestern side of the lake is a 210 m (700 ft) tall halite formation called "Mount Sedo
