Q. Which among the following factors influence the salinity of ocean water?

1. Precipitation
2. Evaporation
3. Ocean Currents
4. Density
5. Temperature

Select the correct code from the options given below:
Answer: 1, 2, 3, 4 & 5
Notes: Salinity means the total content of dissolved salts in Sea or Ocean.
The salinity of Ocean water in the surface layer of oceans depend mainly on evaporation and precipitation.
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 an area.
