Density.
The saltier water is the heavier (per unit volume) it is.
The saltiest water doesn't always sink though. Seawater density is dependent on temperature, salinity and pressure. Most often the effects of temperature are dominant in determining vertical stratification.
No. The Atlantic Ocean is the saltiest ocean. The Dead Sea is the saltiest body of water, but it is not an ocean.
T he Red Sea is the saltiest ocean in the world.
the lowest ocean (if you mean deepest) is the pacific, and the saltiest is the indian.
The saltiest ocean in the world is the northern portion of the Atlantic Ocean. However the saltiest body of water in the world is Don Juan Pond in Antarctica and the saltiest sea is the Dead Sea.
If you are talking in terms of the ocean the smallest is the Indian Ocean. The coldest is the north pole ocean. The warmest is the Indian Ocean. The saltiest is the Atlantic Ocean.
A basic answer is that the densest ocean water is the saltiest - a ship floats higher in salt water (sea) than in fresh water (lake). Also cold water tends to sink towards the ocean floor, or may form a layer mid way.

No, the Atlantic ocean is the saltiest of the oceans.
Yes. The disparities are from global warming and the gulf stream.
I think that it is probably somewhere in the tropics. I know that the average ocean salinity (or the amount of salt in that body of water) is around 35ppt.
