Hope it helps and mark me brainlest answer
The addition of heat energy to a
system always causes the temperature of that system to increase. This is always
true because you are adding heat of a substance to increase its temperature. For example, you are going
to drink a cup of coffee. And you wanted it hot to boost your attention. So you
have to use hot water. In order for your water to become hot or warm, you need
boil it in a kettle. Note that you are going to use an electric stove. The
electric stove gets it energy from the source giving it a hotter temperature to
the water in the kettle. You are applying heat energy to warm the water. So,
the statement is true.

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.
