Consider the following statements relating to Sea Salinity :
1. The ocean salinity depends on evaporation and precipitation
2. Any change in the temperature or density influences the salinity
3. Major source of sea salinity is terrestrial discharge by rivers
Which of the statements given above are correct?
Explanation:
Factors affecting ocean salinity are mentioned below:
(i) The salinity of water in the surface layer of oceans depend mainly on evaporation and precipitation.
(ii) Surface salinity is greatly influenced in coastal regions by the fresh water flow from rivers, and in polar regions by the processes of freezing and thawing of ice.
(iii) Wind, also influences salinity of an area by transferring water to other areas.
(iv) The ocean currents contribute to the salinity variations. Salinity, temperature and density of water are interrelated. Hence, any change in the temperature or density influences the salinity of water in an area
Salt comes from
From precipitation to the land to the rivers to the sea(this is major)
Salt comes up from below, too
