Why doesn't ocean water ever get diluted by fresh water rivers running into the oceans?
Ocean water is diluted by the rivers. Probably the best example of this is where the Amazon river meets the ocean. Approximately 160km away from the mouth of the river Amazon, the ocean water is still fresh enough to drink. It probably doesn't taste very nice though. IN ADDITION: Volume. The amount of fresh water that flows into the ocean can be measured in parts per million. It doesn't have the volume needed to change the salinity of the ocean as a whole. It would be equivalent to adding one drop of food coloring to a swimming pool and trying to notice the difference later. +++ Such dilution is local, but the ocean's salinity is by no means homogenous anyway. The water circulation is cyclic, with vapour from the sea being distilled water. Once it falls as rain or snow, it collects minerals from the rocks the rivers are eroding, helping maintain the sea's overall cocktail of dissolved salts. So the rivers have no real effect on the sea's saltiness overall, but if anything maintain it.
Which condition of ocean water varies with the location and seasons?
salinity
What is an estaury?
This is an area where fresh water from rivers and salt waters from the ocean mix to form saltish water
What does not affect ocean salinity?
Chitin.
The Arctic Ocean is stratified and has limited vertical mixing of water because?
Runoff from large rivers of Canada and Siberia form a stable low salinity layer at the surface.
Do places where rivers pour fresh water into the ocean have low salinity?
Yes, yes they do!!
True or false places where rivers pour fresh water into the ocean have low salinity?
Salinity is a measure of how salty water is. Ocean water is more salty in some places than in others. The answer is yes, places where rivers pour fresh water into the ocean have low salinity because fresh water is normally cold and in warm areas, ocean water evaporates quicker. When this happens, salt is left behind and the ocean water has a higher salinity.
What increases the salinity?
rain, snow, and melting ice add fresh water to the ocean, lowering the salinity there. Salinity is also lower near the mouths of large rivers. These rivers empty great amounts of fresh water into the ocean.
Which areas of the ocean have the lowest salinity and why?
The lowest areas of salinity in an ocean are near where fresh water rivers empty into them. This is because the influx of fresh water creates an area of lower salinity compared to the remainder of the ocean.
What condition would cause the salinity of ocean water decrease?
A river flowing into the sea is causing the decrease in salinity
Where are 3 places in which you can find fresh water?
Rivers lakes and for groundwater
Why is ocean ocean water salinity greatly reduced at the mouths of the amazon Congo and Mississippi rivers?
Because of the high discharge of freshwater
Does water move or circulate between fresh water and salt water?
Yes; rivers run into the ocean at places called Estuaries. What evaporates from the ocean, and is dropped as freshwater in raindrops.
What is the difference between fresh water and ocean?
Ocean water has a higher salinity (salt content) than fresh water does.
The average salinity of the world ocean?
Salinity of the ocean water is defined as the dissolved salt content in a body of water. The salinity of the ocean is 3.5%, the salinity increases as you approach the equator and decreases as you approach the poles.
What is the type of water has a very low salinity content when compared to brackish and the ocean?
Fresh Water
What is the only fresh water part of an ocean?
Icebergs are the only freshwater part of an ocean. When icebergs melt, it results in a decrease in the salinity of ocean water.
