The more salt in water the more buoyant an object becomes. The salt makes the water more denser. Check out the dead sea. Most salt content in any lake or sea.
The density of the salt water is greater than the density of an object. Items sink if their own density is greater than the density of whatever they are trying to float in. Items float to the top if their density is less than the density of what they are floating in, and items hang in the middle if the densities are the same. Adding in the salt gives the water a greater density than the water did had before, so the item doesn't float in freshwater.
We call the amount of mass in a given amount of space the density. For instance, we could measure the mass of fresh water (like water from a stream) in a container. We could then determine the density if fresh water. However, if we filled the same container with salt water, it would have more mass because the ocean water has the mass of pure water plus the mass of the salt.
Since there is more mass in the same volume, ocean water has a greater density then fresh water.
For something to float, it must have a density less than in what it is floating. This means that steam, which is less dense than air, rises (or floats) in the air.
It may seem odd that an enormous ship can float when steel is denser than water. However, if you look at the entire ship you see that there are many places filled with things less dense than water, like air. This means that the density of the entire ship is less dense than that of water and it floats.

∙ 12y agoA boat will sink until the weight of the volume of water pushed aside by the hull is equal to the weight of the boat. Salt water has slightly greater density(weighs more by volume) than fresh water, so a boat will float higher(push less water away) in salt water.

Do objects float more in salt water or fresh water?
salt water
Why do ships sink more in fresh water than in salt water in respect to?
Salt water is more dense than fresh water. So when you're in salt water you float more than when you are in fresh water
Will a ball float higher in salt or fresh water?
Salt water is more buoyant than fresh water is, because salt water is slightly more dense. -- Anything that floats in salt water will float higher than it does in fresh water. -- Anything that sinks in salt water will sink slower than it does in fresh water. -- Anything that just barely floats in salt water may possibly sink in fresh water.
Why does fresh water float on top of salt water?
The salt makes the water more dense.
Do objects float more easily in salt water or fresh water?
Adding Salt to the water increases the density of the water, and therefore makes it weight more per capita. This in turn causes the salty water to push down with more force then water with no salt, causes things that may not float, to float, and things that already float in normal water, to float higher in salty water.
In what type of water would a swimmer float more easily is it salt water or fresh water?
Saltwater.
Is salty water more dense that salty water?
Salt water is more dense than fresh water. A ship would float higher at sea, and lower on a fresh water inland lake.
Do you float in salt water or fresh water which on is more dense?
Salt
Do objects float more in salt water or fresh water?
salt water
Does Egg Float In Salt Water Or Fresh Water?
Fresh eggs float in salt water because the density of salt water is more than the density of the egg. But fresh eggs do not float in fresh water because the density of water is less than that of the egg. Salt increases the density of water.
Why do ships sink more in fresh water than in salt water in respect to?
Salt water is more dense than fresh water. So when you're in salt water you float more than when you are in fresh water

Will an egg float in salt water or tap water?
Eggs float in salt water but not in tap water, which is a fresh water. This is because salt water is more dense than fresh water.
Why does fresh water float on top of salt water?
The salt makes the water more dense.
Is salty water more sense than cold water or more dense than less salty water?
Salt water is denser than fresh water. A ship will float higher on the oceans, and float lower on a fresh water inland lake.
Do objects float more easily in salt water or fresh water?
Adding Salt to the water increases the density of the water, and therefore makes it weight more per capita. This in turn causes the salty water to push down with more force then water with no salt, causes things that may not float, to float, and things that already float in normal water, to float higher in salty water.
Why can't objects float on fresh water?
Any number of things will float in fresh water. Any boat that can be used in salt water will also stay afloat in fresh. However, fresh water has a lower specific gravity than salt water, and as a result, objects that displace a certain amount of sea water will displace more fresh water; they will sit lower in fresh water.
