A lower freezing point than fresh water
Sea water is more dense because the minerals, especially salt, make it more dense.
salt water
salty water is more dense than fresh
Salt water is more dense than fresh water. The added density adds pressure, so the pressure will be greater at the same depth in salt water. This is also the cause of the increase of buoyancy in saltwater.
Ships float in fresh water too. Only a little deeper, since fresh water is less dense than salt water.
Seawater because it contains salt which makes the water more dense than water which does not contain salt.
Answer 1) At the Surface. Answer 2) I disagree with the above answer. For practical purposes water is not compressible. Therefore the density is the same all over. The difference in density at the surface and at the bottom is so small that it is negligible. However, fresh water is less dense than seawater, since the salts dissolved in the seawater makes it more dense. For that reason, if you consider seawater near the mouth of a river, that water will be less dense than the seawater in general.
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.
97% seawater, other 3% is freshwater.
You have it backwards. A ship floats higher in seawater than freshwater. This is because the dissolved salt makes seawater denser. due to the lack of salt content in fresh water. the salinity of ocean water makes it more dense, allowing the boat to sit higher in the water.
No, it is seawater.

A ship will ride higher in salt water than it will in fresh water. Archimedes principle states that an object floatingin a liquid will displace an amount of liquid equal to it's own weight. Salt water is more dense than fresh water. Seawater weighs about 1025 kg·m-3 while fresh water weighs 1000 kg·m-3. Since the seawater is 2.5% heavier, a boat will sit higher when in it than when it is in fresh water
no.they must have fresh water to live.
Flash Distillation
No. Fresh powder is softest.
