Consider the following statements relating to Sea Salinity:
- 1The ocean salinity depends on evaporation and precipitation.
- 2Any change in the temperature or density influences the salinity.
- 3Major source of sea salinity is terrestrial discharge by rivers.
Which of the statements given above are correct?

- A1 and 2 only
- B2 and 3 only
- C1 and 3 only
- D1, 2 and 3
Explanation
Ocean salinity rises with evaporation and falls with precipitation, so statement 1 is correct. Temperature and density changes alter solubility and stratification, influencing salinity, so statement 2 is correct. Rivers carry dissolved salts from the land to the sea, making terrestrial discharge a major source of sea salinity, so statement 3 is correct. All three statements are therefore correct.
