Which events may occur when ocean salinity increases? check all that apply.1) mass of water increases2) freezing point of water decreases3) sunlight in deeper locations decreases4) buoyancy of objects in the water increases5) amount of dissolved gases in water increasesearth & space science question.

1)The mass of water increases.

2) Freezing point of water decreases.

4) bouyancy of objects in the water increases.

Salinity in the oceanic water is attributed by the water coming from other sources like rivers carrying rocks and soil containing salt. Salinity decreases the temperature of water, making it cold and more denser. The cold water settles at the bottom of the ocean. It flows across the oceanic basins as slow currents. The objects being less in density flows over the surface of water. Hence,bouyancy of objects in water increases.
