Question

Give reason salinity and temperature of water are factors causing ocean currents

Answer 1

The salinity and temperature of water causes ocean currents

Explanation:

• The heating causes expansion in water molecules of the ocean.

• The place created by this expansion is generally occupied by  salt and other molecules like calcium.

• The solubility of salt increases in warm water.
• So,the warmer water the more salt and other molecules the ocean water can hold as compared to that of cold water.
• Due  to he increased salinity , the water will start to  sink.
• This will  start a convection current.
• It means the cold water can overlane  warm water , if the salinity of warm water is high enough.
• The natural flow of a current  can be reversed based on density, salinity and temperature of the ocean water.
