Answer:
b. heat energy
Explanation:
Water, which is able to exist in three different states moves from one form to another. Water can move from the ocean to the atmosphere via a process called EVAPORATION. During the process of evaporation, the sun plays a major role by supplying the HEAT ENERGY required to change water from its liquid form in the ocean to its gaseous form in the atmosphere.
Water cycle of the earth helps ensure that water is not lost in any of its forms. Liquid water stored in the ocean gets evaporated as a result of heat energy into the atmosphere as water vapour.
