1. Water review freshwater
S6E3

2. Explain the stages of the water cycle

3. What is the energy source for the water cycle?

4. The sun!

5. the process of heating water, which changes liquid into a gas is __
the process of heating water, which changes liquid into a gas is __. This gas rises into the atmosphere.

6. evaporation

7. What is The collection of water
What is The collection of water? either as runoff that flows to the lakes & oceans or infiltration that sinks underground

8. accumulation

9. Plants take water in through their roots & use what is needed
Plants take water in through their roots & use what is needed. Evaporation from plants is ___.

10. transpiration

11. Clouds form when water vapor cools and condenses from a gas to liquid droplets that stick together. Which stage of the water cycle is this cloud formation?

12. condensation

13. When the clouds get too heavy to hold the droplets of water, what happens?

14. Precipitation falls

15. What are the 4 forms of precipitation? (What falls from clouds???)

16. SLEET
HAIL
Rain snow

17. What is the approximate percent ratio of land to water on earth. A
What is the approximate percent ratio of land to water on earth? A. 3% land: 97% water B. 30% land: 70% water C. 50% land: 50% water D. 70% land: 30% water

18. B. 30% land: 70% water

19. What is the correct order of freshwater on earth from largest to smallest amounts by location? A. air, lakes/rivers, groundwater, glaciers B. groundwater, lakes/rivers, glaciers, air c. glaciers, groundwater, lakes/rivers, air

20. c. Glaciers  groundwater lakes/rivers air
[Most of the freshwater is “locked away” frozen. We need it to stay frozen to help keep our ocean levels along the coastlines from flooding and other climate-related reasons.]

21. If we are in a drought, what change is likely to occur with the water cycle? A. more precipitation falls b. increased run-off C. less groundwater accumulation

22. C. less groundwater accumulation If it is not raining much, then there is not enough water to soak deep into the ground.

23. Using less water is known as ___. Give 2 examples.

24. Water conservation 1. replace old toilets with more efficient ones that use less water 2. turning off the water while brushing your teeth 3. take shorter showers 4. only wash clothes & dishes when you have full loads 5. make sure to fix leaks 6. only water outside when it is not the hottest part of the day

25. A layer of underground rock that holds water is called ___. A. a cave b. an aquifer c. a well

26. b. an aquifer

27. How do we get to groundwater so that we can use it?

28. We drill wells, springs form naturally, artesian wells force water upward
