4. Key Terms Evaporation Condensation Transpiration Heat Energy Solar Energy Precipitation

5. A cycle is any series of events that keeps going around and repeated

6. Forms of Water

8. What drives the water cycle?

9. How does liquid water change into vapor that can go up into the atmosphere? EvaporationEvaporation TranspirationTranspiration 90% 10% What percent of the water in the atmosphere comes from evaporation?

10. Evaporation Evaporation is the process in which water is turned from its liquid form to its vapor form Does this require energy?

12. Transpiration is the process by which plants return water to the atmosphere. After absorbing water from the ground, plants release water through their leaves. Transpiration helps plants stay cool, in the same way perspiration keeps humans and animals cool.plantsatmosphere

13. Condensation Condensation is when water changes from its vapor form to its liquid form Does this require energy?

14. What part does condensation play in the water cycle?

15. What happens when clouds get too heavy? Precipitation

16. Types of Precipitation

17. Evaporation The vapor rises Condensation The Clouds form Precipitation The rain falls Transpiration The movement through plants

18. Last Stage of Water Cycle Water carried to ocean by streams, rivers and ground water
