The density of all water is 1, no matter the amount or location. Humans have the density of 0.9, so humans barely float in all bodies of water.
It is easier to swim in the sea because of the amount of salt in sea water the density of the water is greater which make you float more easily.
It is easier to float because the sea water is denser than water found in a swimming pool. This is caused by the salt in the oceans.
The Dead Sea is known for its high salt content, which makes it easy for humans to float on its surface.
this is because the sea is full of salt (as most people figure out after swallowing most of it) which acts as a buoyant that's why in the dead sea you float a lot easier as it is full of salt. in the swimming pool it doesn't contain as much salt. hope this helps :)
The density of sea water is greater the fresh water. The more greater density the larger is its upward thrust.
The salinitiy of the water allows you to be more buoyant.
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.
The Red Sea a
Sea water is easier to float in, but wave make it harder to swim in.
you float...
a ocean because the salt water makes you float and a pool water doesn't.
It is easier to swim in the sea, as it is salt water as aoposed to fresh water sea water is also much saltier then water in a saltwater pool. that makes the sea water denser and the swimmer comparatively lighter.
