c. clouds and trees

Explanation:

1. The Sun provides the energy to heat water in the water - cycle.
2. When the Sun heats water, it changes from a liquid to a gas through evaporation.
3. The process of water turning into gas is called evaporation.
4. Clouds are formed by the condensation of water vapor.
5. Water falling from clouds is precipitation.
6. Both snow and rain are forms of water falling to the ground.
7. Water gathering in lakes, rivers, and oceans is called collection.
8. Plants release oxygen and water vapor into the air during processes like photosynthesis and transpiration.
9. Gravity pulls rain down to Earth.
10. The Sun provides energy for evaporation and gravity pulls water down as precipitation, helping move water through the cycle.
