1. Evaporation is controlled by the salinity of the ocean.

2. Spatial variation in the seawater salinity is a potent factor in the origin of the ocean currents.

3. Salinity and density of the sea water are negatively correlated.

Select the correct answer using the code given below:

Ocean salinity has significant effects on the physical property of the sea water –

• Freezing and boiling points are greatly affected and controlled by the salts in the sea water.
• Salinity and density of the sea water are positively correlated.
• Evaporation is controlled by the salinity of the ocean.
• Spatial variation in the sea water salinity is a potent factor in the origin of the ocean currents.
• Ocean salinity affects marine organisms and plant community.
