The Dead Sea in Jordan has mind-boggling characteristics. Its mineral composition is unlike any other, so it's an intriguing topic for children and adults alike. Most children can't visit the Dead Sea in person, but Internet photos and hardcopy images can make this beautiful body of water come to life.
The Dead Sea is 10 times saltier than average seawater, according to the National Geographic website. The concentration of salt in the Dead Sea is nearly 34 percent, compared to a 3 percent to 4 percent salt concentration in the Mediterranean Sea, according to the Dead Sea Wonder of Nature website. Kids might enjoy looking at photographs of salt deposits in the Dead Sea.
Continually Gets Saltier
The Dead Sea is getting saltier. There aren't any rivers that originate from the Dead Sea, so the only source of depletion is evaporation. Salt doesn't evaporate -- it's left behind when the water evaporates -- resulting in an increased salt concentration over time. The rate at which water evaporates from the Dead Sea is far greater than the rate at which it gets replenished with rainfall, according to Pitara Kids Network.
No Sea Life
Animals, sea creatures and fish can't survive in water that has a heavy salt concentration. As a result, almost no animal or sea life can be found in or around the Dead Sea. This plays an important role in the circle of life. For example, because there are no fish, some types of birds that normally feed on fish can't survive in the area either. Larger animals that normally prey on the birds never make the region their home because there isn't a sufficient food source.
The heavy salt content creates an unusual floating experience, according to the Dead Sea Wonder of Nature website. Because the water has such a dense concentration of salt, buoyancy is remarkable. Swimmers bob on top of the water like a cork because most of their body rests above, rather than below the surface. Some websites boast that it's impossible to drown in the Dead Sea, but that's incorrect. Discuss with children that even though it's easy to float, it's hard for a swimmer to touch the ground under his feet -- making it difficult to stand up if he trips and enters the water face down or needs to use his feet to roll over. Swallowing large amounts of Dead Sea salt water is also dangerous.
