Consider the following statements relating to Sea Salinity : The ocean salinity depends on evaporation and precipitation Any change in the temperature or density influences the salinity Sea salinity increases due to terrestrial discharged by rivers. Which of the statements given above are correct? 

Consider the following statements relating to Sea Salinity : The ocean salinity depends on evaporation and precipitation Any change in the temperature or density influences the salinity Sea salinity increases due to terrestrial discharged by rivers. Which of the statements given above are correct?  Correct Answer 1 and 2 only

The correct answer is 1 and 2 only

Key Points

  • Sea salinity is the concentration of salt in seawater. It varies with temperature, evaporation, and precipitation. When there is more evaporation, liquid water turns into water vapour. Precipitation occurs when water is released from clouds in the form of rain, freezing rain, sleet, snow, or hail. Hence statement 1 is correct.
  • Please note that when temperature increases, liquid water turns into water vapour and the density of the medium decreases. It directly affects the salinity. Hence statement 2 is correct.
  • Rocks on terrestrial land are the major source of salts dissolved in seawater. Rainwater that falls on land is slightly acidic, and it erodes rocks. Sea salinity decreases due to terrestrial discharged by rivers. Hence statement 3 is not correct.
