What causes ocean water to become denser?

a. the salinity of water and high temperatures.
b. the salinity of water and low temperatures.
c. the concentration of oxygen and high temperatures.
d. the concentration of oxygen and low temperatures.

The salinity of water and low temperatures causes ocean water to become denser.

There are parts of the ocean where hardly any rain falls but warm dry winds cause lots of evaporation. This evaporation removes water – when water vapour rises into the atmosphere, it leaves the salt behind, so the salinity of the seawater increases. This causes the seawater to become denser.

The correct answer between all the choices given is the second choice or letter B. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

answer; //the above statement is (false);

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
