Why is the Dead Sea so salty? Going floating Experts say that it is likely too late to save the Dead Sea and it will eventually dry up. Skip shaving or waxing for a few days before you go! Not only does the water taste bad, but if the salt gets in your eyes it will burn and immediately dry them out.

Staying in for too long can also have a negative impact on your skin. You only have to be a foot or so deep and you can sit down, lean back, and float. This increase in salinity occurs in all landlocked bodies of saltwater.

The Dead Sea holds some of the saltiest water in the world. It is almost six times as salty as the ocean.

The Dead Sea is completely landlocked. As the depth of the water increases, the water gets even more salty, creating salt piles on the sea bottom. Evaporation is the only way water is released from the sea.

With the hot temperatures, the water evaporates fairly quickly. As this occurs, it leaves behind any dissolved minerals in the sea, increasing its saltiness. This is the same process that made the oceans salty.

Since the water became so salty so quickly, animals did not have a chance to evolve under such harsh conditions.

There is no life in the Dead Sea other than a few types of bacteria and one type of algae that were able to adapt to the otherwise deadly sea water. The water in the Dead Sea is extremely deadly to other living things. Any fish that flow downstream to the saltwater are instantly killed. The Dead Sea is not dangerous to humans, however, and they are still able to swim in it. Around 3 million years ago, the Mediterranean Sea reached the East Rift Valley and emptied saltwater into the area.

As time went by, the body of water formed became detached from the nearby lakes as the Mediterranean Sea receded. Ever since then, the Dead Sea has been continually fed water from the Jordan River and other small streams. In , a few young shepherds entered a cave near the sea to find their goat that had run away. At about feet meters below the surface, salt becomes so concentrated, it begins to precipitate or form crystals that fall to the sea floor.

The Dead Sea is located in the Jordan Rift Valley, a long valley created by a geologic fault line called a rift. In addition to being one of the saltiest bodies of water on the face of the Earth, the Dead Sea is also located at the lowest elevation on the planet — more than 1, feet about meters below sea level. At one point, a chain of lakes dotted the mile-long valley, but by about 15, years ago, all had disappeared except for the Dead Sea which itself is a vestige of the larger Lake Lisan that extended from the Sea of Galilee in the north to about 20 miles 35 km south of the southern tip of the present Dead Sea, according to the Minerva Dead Sea Research Center.

The Dead Sea has one tributary — the Jordan River. Exposed to the intense heat of the desert sun, the water in the sea evaporates more quickly than in the ocean, where tides and currents keep water flowing from one area to another, intensifying the salinity levels. In fact, the shores of the Dead Sea offer an almost lunar-like landscape, covered with salt residues and formations that glitter in the sun.

But despite its barren appearance, the Dead Sea does offer some surprises. In , scientists delved deeper than ever before into the Dead Sea and discovered a series of freshwater springs surrounded by thriving colonies of tiny microbes. Probably, one of the most famous organisms that can happily survive in such a severe environment is the Dunaliella algae, which is widely known for its health benefits.

Just a little salt provides ample amounts of magnesium, potassium, calcium chloride, and bromides. In fact, the health benefits of Dead Sea salt have been extolled for thousands of years, beginning with the ancient Egyptians and Romans.
