Facts About The Dead Sea For Kids


The Dead Sea, also called the Salt Sea, is a salt lake bordering Jordan to the east and Israel and Palestine to the west. Its surface and shores are 1,388 ft below sealevel, Earth’s lowest elevation on land. The Dead Sea is 1,237 ft deep, the deepest hypersaline lake in the world. With 33.7% salinity, it is also one of the world’s saltiest bodies of water, though Lake Assal (Djibouti), Garabogazköl and some hypersaline lakes of the McMurdo Dry Valleys in Antarctica (such as Don Juan Pond) have reported higher salinities.

  • This salinity makes for a harsh environment in which animals cannot flourish, hence its name.
  • The Dead Sea is 55 kilometres (34 mi) long and 18 kilometres (11 mi) wide at its widest point.
  • It lies in the Jordan Rift Valley, and its main tributary is the JordanRiver.
  • The Dead Sea is an endorheic lake located in the Jordan Rift Valley, a geographic feature formed by the Dead Sea Transform (DST).
  • The Jordan River is the only major water source flowing into the Dead Sea, although there are small perennial springs under and around the Dead Sea, forming pools and quicksand pits along the edges.
  • 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.
  • The sediment was heavier than the salt deposits and squeezed the salt deposits upwards into what are now the Lisan Peninsula and Mount Sodom (on the southwest side of the lake).
  • Until the winter of 1978–79, when a major mixing event took place, the Dead Sea was composed of two stratified layers of water that differed in temperature, density, age, and salinity.
  • Underneath a zone of transition, the lowest level of the Dead Seahad waters of a consistent 22 °C (72 °F) temperature and complete saturation of sodium chloride (NaCl).
  • The Dead Sea area has become a major center for health research and treatment for several reasons.
  • The mineral content of the water, the very low content of pollens and other allergens in the atmosphere, the reduced ultraviolet component of solar radiation, and the higher atmospheric pressure at this great depth each have specific health effects.
  • The Dead Sea temporarily comes to life in the wake of rainy winters.
  • Both Jordan and Israel have established nature reserves around the Dead Sea.
  • Potash City is a small community on the Jordanian side of the Dead Sea.
  • Somewhere, perhaps on the southeastern shore, would be the cities mentioned in the Book of Genesis which were said to have been destroyed in the time of Abraham: Sodom and Gomorra (Genesis 18) and the three other “Cities of the Plain”, Admah, Zeboim and Zoar (Deuteronomy 29:23).
  • The Palestine Potash Company was chartered in 1929, after its founder, Siberian Jewish engineer and pioneer of Lake Baikalexploitation, Moses Novomeysky, worked for the charter for over ten years.
  • Both companies use extensive salt evaporation pans that have essentially diked the entire southern end of the Dead Sea for the purpose of producing carnallite, potassium magnesium chloride, which is then processed further to produce potassium chloride.
