Explanation:
The water cycle refers to how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation.
<em>Ice and glaciers are part of the water cycle, even though the water in them moves very slowly, they are considered as a form of storage but it stills evaporates into the atmosphere entering the cycle. This also applies to the ocean and surface water as they are in constant evaporation because of their exposition to the sun. </em>Therefore the correct answer is D.
