With reference to the latitudinal distribution of salinity in the oceans, which of the following statements is correct? I. The highest salinity is recorded in the equatorial regions. II. The salinity of the oceans of the Northern Hemisphere is higher than that of the Southern Hemisphere.

With reference to the latitudinal distribution of salinity in the oceans, which of the following statements is correct? I. The highest salinity is recorded in the equatorial regions. II. The salinity of the oceans of the Northern Hemisphere is higher than that of the Southern Hemisphere. Correct Answer Neither I Nor ॥ 

Latitudinal distribution of salinity in the oceans indicates the salinity level in oceans depending on the angle of sun rays to which ocean bodies are exposed and hence, their density with salt contents in it.

Important Points

  • Salinity decreases from the equator to the poles on average.
  • It's worth noting that the maximum salinity is seldom found near the equator, despite the fact that this region experiences high temperatures and evaporation.
  • At approximately 30°–35° N and 30°–35° S, the subtropical zones called the horse latitudes are belts of high evaporation that produce major deserts and grasslands on the continents and cause the surface salinity to rise.
  • However, significant rainfall decreases the relative amount of salt. As a result, only 35% of salinity is found near the equator.
  • In the poles, the heat distribution from the sun and hence, evaporation differs from solstices.
  • But on average the salinity remains the same and hence, the density too.

​Therefore, Neither I nor II is correct.
