Which is denser ocean water or fresh water?
ocean water, because it is saltier.
What is denser fresh water or ocean water?
Sea water is denser, not only that, different oceans have different densities.
Why is ocean water denser than freshwater or pure water?
The water of the oceans is denser because of the high level of salt it contains.
What happens to ocean water as it becomes denser?
The water gets cooler
Where does deep ocean water originate?
The two main sources of deep water are at the poles, where the cold temperatures and the higher salinity make water denser and sink. Water is saltier here because when the water freezes, salt is left behind in the water, making salinity rise.
As deep ocean water becomes colder it also becomes?
denser
What carries water toward the poles?
Ocean currents.
What carries warm water the poles?
Ocean currents.
What causes ocean water near the poles to be colder than ocean water near the equator?
the sun's rays strike the water at a angle at the poles APEX
Why is ocean water near the equator warmer than ocean water at the poles?
The ocean receives most of its heat along the equator, where incoming solar radiation is about double that received at the poles. Hence, sea surfaces are much warmer along the equator than at the poles.
When water gets denser how does it move?
I think it sinks toward the ocean floor.
How does water freezing at the poles helps create deep ocean currents?
When seawater freezes the salt is excluded from the ice and stays with the portion that remains liquid. The result is highly saline water called brine. The brine is denser than normal seawater and so sinks the the ocean floor, forming deep currents.
