because the salt water ie heavier than fresh water
Freshwater is less dense than saltwater, and so it tends to float on top, as less dense things tend to float on denser things.
The salt makes the water more dense.
Copper is more dense than water so a piece of copper will sink and not float in fresh water. However if the copper is formed into a container like shape similar to that of a boat it will stay on top of the water. For a better understanding of why, look up Archimedes Principle.
Nope Most string should float on top of water becomes the string material is less dense than he water.
No, but different salinity levels can float over each other. Basic properties of diffusion rule out the very concept of the two able to float over the other but if two different concentrations of water come in contact they will mix and eventually form one homogeneous solution. However if a large body of water has salt, such as an ocean, the general rule is "The deeper you go the saltier it gets" Hope I answered your question!

Assuming equal temperatures it does not. The fresh water will be on top.
When salt is dissolved in water, as it is in ocean water, that dissolved salt adds to the mass of the water and makes the water denser than it would be without salt.Because objects float better on a dense surface, they float better on salt water than fresh water. The denser the salt water, the easier it is for objects to float on top of it.
no< fresh water will become mixed with the salt water

The Iceberg if made up of fresh water on top and saltwater at the bottom.
You float better in saltwater. For instance, the Dead Sea is so salty that you cannot sink or even swim in it. You can only float on top. It does not feel wet, but more like warm, runny honey. It is extremely bitter if you are unlucky enough to taste the Potassium-heavy water. Strangely, Dead Sea does not have a salty taste.
Saltwater freezes too, just at a couple degrees lower than fresh water.

Basically, if something is lighter than water, it will float. If the water is somehow made heavier, more things will be lighter than it. If you add a lot of salt to water, the body of water becomes heavier. Something that is heavier than water might be lighter than saltwater and float in saltwater but not normal water.
