Weather and Water Cycle Study Guide
I. Review vocabulary words for weather and the water cycle.
II. Short Answer: Answer the following questions in complete sentences by restating the
question.
1. What kind of weather is likely to occur if a warm air mass moves over a cold air mass?
Stratus clouds form ahead of the front and it produces steady rain or snow (p. 135)
2. Which type of precipitation occurs when water vapor turns directly into ice?
Snow (p.123)
3. What does a rising barometer often tell about the weather? Cold air and a low chance
of rain (p. 132)
4. What happens to water vapor as it rises higher and higher in the air? Water vapor cools
and condenses to form a cloud (p.122)
5. Which instrument measures humidity? Hygrometer (p. 132)
6. Which instrument measures air pressure? Barometer (p. 132)
7. Which instrument measures wind speed? Anemometer (p. 132)
8. Draw a diagram of two air masses. Label the temperature of each air mass (warm and
cold) and where the front would be located.
See diagram on page 135
9. Draw a diagram of the water cycle. Be sure use the following words as you label your
diagram: evaporation, condensation, precipitation, and ground water)
See foldable in Science Composition book or page 120 in the textbook
10. What happens during the process of evaporation and condensation? Give an example of
each.
Evaporation is the process in which a liquid changes to a gas. An example of
evaporation is when the water evaporates from the ocean. Condensation is the
process in which gas changes to a liquid. An example of condensation is when a coke
can sweat and water droplets form on the outside of the can. (p.110-111)
11. What weather instrument measures temperature?
Thermometer (p. 132)
12. What weather instruments measures wind direction?
Wind sock or wind vane
13.
What percentage of the earth is water? 75% land? 25%
14. What percentage of the world’s water is in the ocean? 97.3% (97%)
15. At what temperature will water boil? (Give your answer in both Celsius and Fahrenheit)
100˚ C (Celsius) or 212˚ F (Fahrenheit)
16. At what temperature will water freeze? (Give your answer in both Celsius and
Fahrenheit)
0˚ (C) Celsius or 32˚ (F) Fehrenheit
17. What are the three states of matter?
Solid, liquid, gas (p. 110)
18. What are the four types of precipitation?
Snow, sleet, hail, and rain (p. 123)
19. What causes air pressure in an area to change?
Air pressure in an area changes because a new air mass moves into the area. Air
masses move because the uneven heating of Earth causes air to move in currents.
