1. The Water Cycle
By: Amelia Leveille

2. Diagram of the water cycle

3. Facts about the
water cycle
• The chemical symbol
for water is H2O
• The sun is the driving
force of the water
cycle
• Only 3% of water on
earth is freshwater
• When ever water
changes from one
state to another and
moves from one place
to another, it either
gives off or absorbs
energy
Runoff/
Collection
EvaporationCondensation
Precipitation
Note: If precipitation is
absorbed by a plant, then it
goes through transpiration
(releasing water from its
leaves) rather than
evaporation

4. Words to know
 Water cycle - the continual movement of water among
Earth's atmosphere, oceans, and land surface through
evaporation, condensation, and precipitation
 Evaporation - the process by which molecules at the
surface of a liquid absorb enough energy to change to a
gas
 Condensation - the change in state from a gas to a
liquid
 Precipitation - any form of water that falls from clouds
and reaches earth's surface as rain, snow, sleet, or hail
 Transpiration - the process through which water is lost
through a plant's leaves
 Runoff - water that flows over the ground surface
rather than soaking into the ground

5. Ready for some questions?

6. Question #1
o Which step of the water cycle turns
water vapor into clouds?

7. Correct!
Water Vapor Condensation Clouds

8. Question #2
o What happens after a plant absorbs
water?

9. Correct!
o Transpiration - the process
through which water is lost through
a plant's leaves

10. Question #3
o How much of earth’s water is
freshwater?

11. Correct!
o Only 3% of earth’s water is
freshwater
Saltwater Freshwater

12. Question #4
o What is the chemical symbol for
water?

13. Correct!
H2O

14. Question #5
o Where does the energy that powers
the water cycle come from?

15. Correct!
o Energy from the sun powers the
water cycle!

16. Now time for some bonus
questions…

17. Bonus #1
o What does H2O mean?

18. Correct!
o H2O means 2 atoms of hydrogen
and 1 atom of oxygen

19. Bonus #2
o In 20 minutes, one thunderstorm
can send down over _____ gallons
of water.
a) 14,300
b) 500,000
c) 3,400,000
d) 125,000,000

20. Correct!
125
million
gallons of
water

21. Congratulations!
I hope you learned a lot about the water cycle!
