Q: Identify the factor that does NOT affect the salinity of the ocean.
  • A. The rate of evaporation and precipitation
  • B. Wind
  • C. The amount of fresh water flowing into the ocean
  • D. The type of marine organisms found in the water bodies
Correct Answer: Option D - Marine microorganisms and their types found in water bodies in the oceans do not affect sea/ocean salinity. Following are the factors affecting sea salinity: (i) Evaporation and supply of rain water/precipitation. (ii) Arrival of river water. (iii) Air pressure and wind direction/wind flow. (iv) Ocean water flow means the amount of fresh flowing water in the ocean. • Ocean salinity is measured as the amount of salt present in sea water per thousand grams. • Ocean salinity is found between 33% to 37%. • The salinity of the Dead Sea is (238%). • The lake with the highest salinity in the world is Von Lake of Turkey (330%).
