Question

Explain the distribution of salinity around the tropic of cancer and tropic of Capricorn

Answer 1

Overaly there is highest salinity water along the both tropics on 23 degrees North and 23 degrees south.

Evaporation is high in both tropics due to high temperature and very low precipitation.

This is because all the processes that act to change salinity occur at the surface not deep in the ocean.

Answer 2

The Tropic of Cancer and the Tropic of Capricorn experiences increased evaporation and low precipitation.

Explanation:

• The Tropics of Cancer and Tropic of Capricorn is present at 23°N and 23°S latitudes.
• The salinity of water is highest over here.
• The evaporation rate is high due to high temperature in these regions.
• Moreover, the precipitation is also low in these regions.
• The salinity of water is also high at the equator.
• But the salinity of water at the equator is lower than the Tropic of Cancer and Tropic of Capricorn.

• This happens due to the increased rate  of precipitation that falls at the equator than the tropics.
• Th salinity of water is the lowest near 60°N and 60°S latitudes.
• This is because of  cold temperatures and high precipitation rate.

• Moreover the melting of glaciers in these regions acts as a dilute to the salinity of water.
