What causes salinity to change? Using the above interactive display and description of the great ocean conveyor belt, what do you think would happen if: a. The ocean temperatures rose 5 degrees? b. The ocean becomes more saline? c. Less saline?

Evaporation and not enough rain can cause the salinity of the ocean to increase.

Explanation:

The great ocean conveyor is also known as the gulf stream. The gulf stream is a circulation system which depends on temperature and salinity for its movement. This is caused by a constant variation in the salinity and temperature in the world oceans at a given time.

a) If the ocean temperatures increase by 5 degrees then there will be higher sea levels due to the fact that cooler water results in denser waters which also result in sinking waters.

b) If the ocean becomes more saline then we will have denser waters also which will result in a decrease in the sea level and ocean temperature. it is important to note that an increase in salinity results from high evaporation.

c) When the ocean becomes less saline, then we can assume there has been enough supply of fresh waters to the ocean. This will result in an increase in the sea level.
