The document discusses the salinity of ocean water, including that salinity is measured as grams of dissolved salts per 1000 grams of seawater. The main contributor to ocean salinity is dissolved sodium chloride. Factors like evaporation, rainfall, melting ice, and ocean currents can affect salinity levels in different regions. The document was authored by Reshma Raj, a social science student providing information on ocean water salinity.

- 3. Salinity of Ocean Water
- 4. Salinity of ocean water • Salinity of oceans is the amount of salt present in sea water.
- 5. Salinity is usually expressed as the number of grams of dissolved salts in 1000 grams of sea water
- 6. • The main reason for the salinity of oceans is the dissolved sodium chloride
- 7. Minerals in Sea Water • Sodium Chloride • Magnesium Chloride • Magnesium Sulphate • Calcium Sulphate • Potassium Sulphate • Calcium Carbonate • Magnesium Bromide
- 8. Factors Affecting Salinity • When evaporation increases salinity increases • Salinity will be low in regions that receive heavy rainfall • Salinity will be comparatively low at estuaries • Water reaching the oceans from melting ice causes a fall in salinity. • In areas where cold and warm currents meet salinity is comparatively low.
