Answer:
The correct answer is an increase in salinity.
Explanation:
ocean water contain high concentration of sodium chloride(NaCl) salt.The large amount of NaCl present in the ocean water makes it both hypertonic and denser.
Due to the presence of huge amount of sodium chloride the osmotic pressure of the ocean water is also very high which causes the ocean water to become denser.
Answer:
a decrease in temperature and an increase in salinity.
Explanation:
When the temperature of ocean water decreases, its density increases. This can be easily explain by comparing the densities of water at room temperature, cold water and when the water freezes into ice. The densities increases and the temperature decreases.
Salinity is a measure of the level of salt in ocean water. Thus if the salinity increases, the density of the water would increase. This shows that the water contains more dissolved mineral salt.
