why are there differences in the salinity of oceans?
Answers
Evaporation of ocean water and formation of sea ice both increase the salinity of the ocean. However these "salinity raising" factors are continually counterbalanced by processes that decrease salinity such as the continuous input of fresh water from rivers, precipitation of rain and snow, and melting of ice.
The content of the salt in ocean water is called salinity of water.
There are differences in the salinity of ocean water.
Because of Evpouration.
Precipitation.
In coastal regions by the fresh water flow from rivers and in polar regions by the process of freezing and thawing of ice.
Winds by transferring water to other areas.
The ocean currents.
salinity means the total content of dissolved salt in sea water
the sea is enclosed by the land then fresh water cannot flow into the sea and salinity will be high
in the equatorial area where the evaporation is high due to the high temperature the salinity will be more
