Seawater has very high levels of sodium , salt, from materials in the sand, freshwater, lakes and ponds, have very low, if any salt levels , so, never consume seawater without first filtering it, it will kill you.
a salt water lake has a freshwater inlet but and inland sea has no inlet.
The major ions in sea water are chloride, sodium, sulphate, magnesium, calcium, potassium, bicarbonate, bromide, strontium,boron and flouride.
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.
They can be. It's all up to whether it has an outlet or not. Lakes with outlets are generally freshwater unless they are too close to the ocean and get intruded with seawater. If they have no outlet the minerals accumulates and the lake becomes salty.
It doesn't make a difference weather it is saltwater or freshwater because they will cool at the same rate it is just that when saltwater evaporates it will leave the salt particles behind.
Seawater has a higher concentration of salts and minerals compared to freshwater. Seawater also has a higher density and freezes at lower temperatures than freshwater. Additionally, seawater has a higher pH and different composition of dissolved gases compared to freshwater.
You've already answered your own question. The difference is that feshwater lochs contain fresh water while seawater lochs contain seawater.
brackish
Seawater is more dense than freshwater. Therefore the seawater would sink lower than the freshwater. Ships do indeed stay higher in seawater because of the higher density or specific gravity of seawater over freshwater
its a seawater fish
Salt
Goldfish are freshwater, not saltwater.
It is 787.975 in seawater and freshwater's is 211.
higher levels of salt and other minerals, making it more saline than freshwater. Seawater also has different organisms and ecosystems adapted to its unique conditions compared to freshwater environments. Additionally, seawater has a higher density and freezing point compared to freshwater.
Seawater is denser than freshwater because it contains dissolved salts and minerals, such as sodium and chloride, which add weight to the water molecules. These dissolved substances increase the overall mass of seawater and make it denser than freshwater.
