salinity
saltwater has salt in it, freshwater does not.
No Oceans are not Freshwater, they are salt water
Ocean water has salt in it, Freshwater does not.
The main difference between marine and freshwater ecosystems is the salt concentration in the water. Marine ecosystems have high salt concentrations, whereas freshwater ecosystems have low salt concentrations. This difference in salinity influences the types of organisms that can thrive in each ecosystem.
Salt in the water. Salt water.
No. Lake water is freshwater and ocean water is saltwater.
The difference in bodies of water is usually where they are located and the type of water they contain. The difference between a sea and ocean is just that a sea is attached to an ocean and surrounded by land. A lake is usually freshwater and located in a natural depression while a river usually flows over a long distance one way.
Maybe that saltwater animal can endure hard water and freshwater animals can't.
Yes; rivers run into the ocean at places called Estuaries. What evaporates from the ocean, and is dropped as freshwater in raindrops.
Ocean water has a lower freezing point than freshwater due to the presence of dissolved salts, which lowers the freezing point of water. The salt in the ocean water disrupts the hydrogen bonds between water molecules, making it harder for the water to freeze. This is why ocean water freezes at a lower temperature than freshwater.
An ocean is a large body of water. You look at what you 'see'.
there is no difference between sea water and ocean water because there the same thing in different words. good guestion though...
