your answers.
Part I- Fill in the blank.
1.
Meteorologists classify clouds based on their shape and height.
2. Humidity is the amount of water vapor in the air.
3. Air is made up of molecules.
4. Warm air rises and creates low pressure.
5. When molecules move slowly the air is colder.
6. Water vapor condenses around particles to form clouds.
7. Relative humidity is the amount of water vapor in the air compared to amount
needed for saturation.
8. Cumulus clouds have flat bases.
9. Stratus are clouds that are flat and sheet like. They form in layers.
10. Which type of clouds are made of ice crystals? Cirrus
11. Cumulus are clouds that are puffy, white, and have flat bases.
12. How would you describe a nimbus cloud? A rain or snow producing cloud.
13. Precipitation is water falling from the clouds.
14. Cloud prefixes tell the height of the clouds.
15. The prefix “cirro” means high.
16. The prefix “alto” means middle
17. Where would you find a altocumulus cloud? In the middle of the sky.
18. Which type of cloud would give you a thunderstorm? Cumulonimbus
19. Which type of cloud would give you snow flurries or light snow? Nimbostratus
20. Which type of cloud would produce a tornado? Cumulonimbus
21. Which type of cloud would give you all day rain or snow? nimbostratus
Part III- Ture or False
22. F
Clouds form in warm air.
23. T
Saturation is when air is filled with water vapor
24. T
Cold air can hold less water vapor than war air.
25. T
As air rises the amount of water vapor stays the same.
26. F
Warm air can hold less water vapor than cold air.
27. F
Fog is an example of a cumulus cloud.
28. F
Evaporation is when water goes from a gas to a liquid.
29. T
30. F
31. T
Clouds only form when air’s relative humidity is 100%.
Clouds form in high pressure.
Stormy weather usually come is low pressure.
