1.  Name the process in which liquid water turns to a gas.

2. EVAPORATION

3.  Name the process in which a gas turns back into a liquid.

4. CONDENSATION

5.  When water pools in large bodies, such as lakes, rivers or oceans it is called…

6. ACCUMULATION

7.  Rain, snow, sleet and hail are a form of what?

8. PRECIPITATION

9.  What type of cloud forms close to the ground?

10. FOG

11. What type of precipitation is this?

12. HAIL

13. Which process is the arrow pointing to?

14. Evaporation

15. Which process is the arrow pointing to?

16. SURFACE RUNOFF

17. Which process occurs at the “X”

18. CONDENSATION

19.  What happens when the water droplets in a cloud become too heavy for winds to keep them in the air?

20.  They fall to the ground as PRECIPITATION.

21.  What are the three types of SOLID precipitation?

22.  SNOW, SLEET, HAIL

23.  When raindrops fall through very cold air near the ground, they freeze, changing into tiny bits of …

24. SLEET

25.  This type of precipitation forms when the air temperature is close to or below freezing (32˚F). The water vapor turns directly into a solid crystal.

26. SNOW

27.  What is the driving factor behind water changing form one state to another?

28. TEMPERATURE

29.  What is the difference between groundwater and surface runoff?

30.  GROUNDWATER- Water that seeps into the ground (think about watering a flower). Groundwater is stored in tiny holes, or pores, in soil and rocks.  SURFACE RUNOFF-Precipitation that flows across the land’s surface and is not absorbed will flow into rivers.  GROUNDWATER- Water that seeps into the ground (think about watering a flower).

31.  How do clouds form?

32.  Clouds form when water vapor EVAPORATES and then CONDENSES into water droplets.

33.  How does snow from the top of a mountain one day end up as a cloud?

34.  The sun’s energy will melt the snow and the snow will runoff into the ocean and collect or accumulate. The liquid water from the ocean will evaporate and then condense into a cloud.

35.  What is transpiration?

36.  TRANSPIRATION is the process in which excess water evaporates out of the plants leaves.

37.  Water droplets gather with these types of particles to form clouds.

38. DUST PARTICLES

39. BONUS  What happens to the molecules in a solid when heat is added?

40.  The molecules gain energy and begin to spread apart. The solid (ice cube) turns into a liquid (water).

41. BONUS  What happens to the molecules in a liquid when heat is added?

42. The molecules gain even more energy and turn into a gas-EVAPORATION

43. BONUS  What happens to the molecules in a liquid when heat is TAKEN AWAY?

44.  The molecules lose energy and turn into a solid (liquid water turns into an ice cube).

45. BONUS QUESTION  What happens to the molecules in gas when heat is TAKEN AWAY?

46.  The molecules lose energy and come together or condense.

47. BONUS  What type of clouds are found at low altitude and form a “blanket” over the sky?

48.  STRATUS

49. BONUS  What type of cloud is “puffy” and found at middle altitudes?

50. CUMULUS

53. BONUS  What type of clouds form HIGH in the atmosphere and are made of ice?

54. CIRRUS

55. Explain how hail forms based on this picture.

56.  Hail forms in severe thunderstorm clouds when raindrops in the clouds COLLIDE with bits of ICE. The drops freeze, forming a hailstone. Winds PUSH THE HAILSTONES BACK UP into the cloud and the hailstones grow larger.
