Answer:
Higher the salinity, more is the density.
Step-by-step explanation:
- The oceanic water is a large storehouse of heat and salinity. The salinity is higher at someplace while it's lower at some places is due to the presence of freshwater and cool water that is less dense.
- Areas of higher salinity are due to the high evaporation, less precipitation, and influx of rivers. The warm water floats at the top while the cold and cool water at the bottom.
