Salt water is denser that fresh water, so a swimmer (and ships) float higher in saltwater.
Because salt water is denser....and rises to the upper so it is easy to float
Because there is salt in sea water and salt makes you float better so is easier to swim.
Sea water contains lots of dissolved salts. Thus the density of the salty sea water is more than that of water in swimming pools, and the salty water lifts you more than fresh water, which make swimming easier.
probally fresh because no salt in mouth or eyes addition: it is easier to float/swim in seawater since seawater is denser than fresh water.
You are more buoyant in salt water than in fresh water, so it takes less energy just to stay afloat, making it easier to swim.
I don't know about health benefits, but...You are more buoyant in salt water, but fresh water feels better on the skin. salty water is the best to swim in because if your ill every year you can swim in it and you will not be ill for a year
It is easier to float, in any case, because salt water has a greater density.
Well let me tell you why they die in pure water. A good explanation is that the water might have bacteria, or position in it. Or the water is not fresh for fishes to swim in or eat nor survive. " "!
ofcourse you can attract more water to pull so youll swim easier
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.
They live in marshes near water and it makes it easier to swim and walk on wet land.
You only float in water if you are less dense than it. The dead sea has a much higher salt concentration than normal sea, therefore it is more dense. This means the difference in density between you and the water is greater, and so you have more boyancy - you float easier.
