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.
Why does the addition of rain and river water to the ocean not decrease the ocean's overall?
The addition of rain and river water to the ocean does not decrease its overall salinity because rain and river water are fresh water sources with low salinity levels. While these sources do mix with the ocean water, the vast volume of the ocean dilutes the impact of the fresh water input, thus maintaining the ocean's overall salinity.
Ocean water has a higher what than fresh water?

Is the indian ocean fresh or salt water?

Where is the majority of earth's fresh water located?

Can ocean plants survive on fresh water?

How much fresh water is in the ocean?
The Pacific Ocean is salty, there is no fresh water in it.
What is the photic zone of the ocean-?
The photic zone of the ocean is the surface of the ocean that receives sunlight.
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.
How shark could stay in there ocean?
Most sharks remain in the ocean, while some species of the Bull Shark (Ganges and Lake Nicaragua) have adapted to fresh water. Great Whites can briefly tolerate fresh or brackish water, also.
Why is ocean water more dense than fresh water at the same temperature?
Ocean water is more dense than fresh water at the same temperature because it contains dissolved salts and minerals which increase its mass without significantly affecting its volume. This higher density allows ocean water to exert greater pressure at depth and affects ocean circulation patterns.

Do ships in the general lakes need more or less ballast than ocean-going ships?
Ships need more ballast in the ocean because the salt helps to keep them a float.What we know is that salt water is about 3% more dense than fresh water and that ships use the water they are floating in for ballast.Say an ocean ship needs 10 tonnes of ballast to get to it's stable water line. The volume of 10 tonnes of seawater would equal 9.7m3.That same ship will float slightly lower in fresh water since fresh water is less dense. It will need 3% less ballast weight (9.7 tonnes) to get to the same stable water line in fresh water. The volume of 9.7 tonnes of fresh water would equal 9.7 m3.So, the ship in the ocean requires 3% more ballast weight than the ship in fresh water, but the ballast volume is the same in both cases.
