Water Cycle, Clouds, and Weather Test Study Guide
Multiple Choice
1. The temperature at which water becomes a solid is 32° F or 0°C.
2. The boiling point of water is 212°F or 100° C.
3. When water condenses onto dust particles in the atmosphere, this
results in clouds.
4. The water cycle is powered by the sun.
5. What causes liquid water to change to water vapor? heat
6. Susan leaves a shallow dish of water on a window sill for one week.
What do you predict will happen to the water? It will all evaporate.
7. A stratus cloud at or near the surface of the Earth is called fog.
8. Tropical climates are located near the equator.
9. If an area is very cold in the winter and very hot in the summer, where is
it most likely located? inland
10. A prediction about future weather conditions is a forecast.
11. The measurement of the amount of water vapor in the air is humidity.
12.The blanket of air surrounding the Earth is the atmosphere.
13. A large region of air with nearly the same temperature and water vapor
throughout is an air mass.
14.A boundary between two air masses that have different temperatures is a
front.
15. The constant movement of water between the air and the Earth’s surface
is the water cycle.
16.Solid or liquid water that falls from clouds is precipitation.
17. This table summarizes the weather in a Georgia city during one week in

Short Answer
19. Draw and describe three kinds of clouds.
Cirrus clouds are thin, wispy, featherlike clouds. They are in the
higher levels of the troposphere.
Stratus clouds are flat like a blanket. They are in the lower level of the
troposphere and may even touch the Earth’s surface as fog.
Cumulus clouds are puffy white clouds that look like cotton balls.
They are in the lower level of the troposphere.
20. Why does water melt or freeze as it falls to the ground from a cloud?
The temperature of the air that precipitation falls through may cause it
to freeze or melt.
21.Explain the difference between climate and weather. Weather is the
condition of the atmosphere at a given time and place. Climate is the
pattern of weather in an area that repeats over a period of time.
22. Name and describe the 4 stages of the water cycle.
1. Collection- Water collects in puddles, streams, lakes, and oceans.
2. Evaporation- Water molecules heat and become water vapor that
rise into the atmosphere.
3. Condensation- Water vapor cools and condense into water
molecules that form clouds.
4. Precipitation-Water drops become heavy and fall back to the
Earth’s surface as solid or liquid precipitation.
