Explanation:
As the ocean water evaporates from the surface, the waters left behind become more concentrated with salts because salt content per volume increases as the water volume decreases from evaporation.
Therefore, more energy is required to evaporate more water because the salt concentration acts like impurities. Impurities increase the boiling point of water or other solutions by lowering the vapour pressure of water.
