2. Water Cycle

3. Water Cycle
Water moves from the surface of the Earth to the air and then back to Earth’s surface again.

4. Water Cycle
The water cycle is powered by the …
SUN

5. Evaporation Did you know?
Write the word “evaporation” on your water cycle diagram.
Did you know?
When water evaporates from the ocean, the salt is left behind.

7. Transpiration
(air)
Write the word “transpiration” on your water cycle diagram.

9. Do you think….
the Earth’s air gets more water vapor from evaporation or transpiration?
Why?

10. Did you say evaporation, because the Earth has so much water?

11. Condensation
Write the word “condensation” on your water cycle diagram.
Have you seen water vapor in our air cool and condense on a water bottle or glass?

13. Have you seen water vapor in our air cool and condense in the sky?

14. Precipitation
snow
sleet
Write the word “precipitation” on your water cycle diagram.

16. Precipitation - Sleet

17. Precipitation - Hail

18. Precipitation
Do you think precipitation is salty, like the water in the ocean?
Remember, when water evaporates from the ocean, the salt is left behind.
Precipitation is fresh water, not salt water.

19. Precipitation Where does all the precipitation go?
Can you tell from your water cycle diagram?
Some precipitation is stored in ice and snow.
Some precipitation becomes runoff.
Some precipitation is absorbed into the ground.

20. Runoff
and lakes
Write the word “runoff” on your water cycle diagram.

22. Infiltration
Some precipitation is absorbed into the ground and becomes soil moisture, and some becomes groundwater.
Write the word “infiltration” on your water cycle diagram.

23. Vocabulary Words Water cycle Precipitation Condensation Evaporation
Transpiration
Runoff
Can you put the steps to the water cycle in order?

24. Quiz

25. What is the process that occurs when water changes from a liquid to a gas, caused by heat?

26. What are water droplets that fall from the atmosphere in the form of rain, sleet, snow, or hail?

27. What is the passage of water vapor from a plant to the atmosphere?

28. What is rainfall that is not absorbed by soil and travels to the ocean?

29. What is the cooling of water in the atmosphere changing gas to a liquid?

30. What are the changes to water when it evaporates into the air, condenses into clouds, and then precipitates down to Earth?
