What happens when fresh water meets salt water?
As fresh water is less dense than saltwater, it floats above the seawater. A sharp boundary is created between the water masses, with fresh water floating on top and a wedge of saltwater on the bottom. Some mixing does occur at the boundary between the two water masses, but it is generally slight.
How does freshwater affect the salinity of ocean water?
The freshwater added at the surface dilutes the seawater, reduces the salinity and so makes the seawater less dense. Seawater can also be less saline near land, where rivers add freshwater. It is this open structure that makes ice less dense than liquid water.
Does saltwater mix with freshwater?
Brackish water, also sometimes termed brack water, is water occurring in a natural environment having more salinity than freshwater, but not as much as seawater. It may result from mixing seawater (salt water) with fresh water together, as in estuaries, or it may occur in brackish fossil aquifers.
How does salt water turn into freshwater?
In some areas, salt water (from the ocean, for instance) is being turned into freshwater for drinking. That may seem as easy as just boiling some seawater in a pan, capturing the steam and condensing it back into water (distillation).
How do you sanitize rainwater?
