The Dead Sea has a high salt concentration, making the water denser and providing more buoyancy, making it easier for objects, including humans, to float.
The DEAD SEA 'Jordon'
The Atlantic and Pacific are oceans, not "seas". The salinity is about the same, so there isn't much difference in being able to float. The Dead Sea has a very high salinity, and it's very easy for people to float there. Same with the Great Salt Lake.
Pretty sure it's the Dead Sea
Yes because there is so much salt in dead sea water the water is denser making you relatively lighter compared to normal water.
because it has so much salt in it that it enables the body to float instead of sinking in the water
Assuming it's a regular steel anchor, an anchor, can't float in the dead sea. Dead Sea water is dense and buoyant for being water, but it's not THAT dense.
The Dead Sea.
It is so salty that you can float without trying.
The water in the dead sea has a high concentration of salt, so it has a higher density than normal sea water and a much higher density than regular water. With a higher density the upthrust (force upwards) in the water is larger so it can support more weight than other water.
Yes, people can float in the Red Sea, because there is a large amount of salt in the Red Sea. Therefor, objects including people, have more buoyancy so we can float. If you do not know what buoyancy is, it is the ability to float
The Red Sea a
because of a lot of salt is in it The dead sea has no outlet. Water flows into it but not out. The area where the dead sea is is an arid zone so rainfall is low. Water evaporates from the dead sea but because there is not much water flowing into it the dead sea becomes concentrated with mineral salts and that makes it dense.
