greater over the oceans than over land.
2. If a city receives 24 inches of snow, it is the equivalent False
to 18 inches of rain.
3. An important factor in the production of rain by the False
collision-coalescence process is the number of ice
crystals in the cloud.
4. In a cloud composed of water droplets and ice crys- False
tals, the saturation vapor pressure is less over the
droplets than over the ice.
5. There are many types of precipitation. Let's think one hundred times larger
about the typical, however. A typical raindrop is about
____ than a typical cloud droplet.
6. In the winter, you read in the newspaper that a Freezing rain
large section of the Midwest is without power due
to downed power lines. Which form of precipitation
would most likely produce this situation?
7. Precipitation with the greatest size (diameter) is ____. a hailstone

Condensation onto hygroscopic nuclei is possible at
relative humidity less than 100 percent due to the ____.
10. Found in certain regions of the cloud formation, a a liquid droplet observed
supercooled cloud droplet is ____. at temperatures below 0
degrees Celsius (32 de-
grees Fahrenheit)
11. Typical cloud droplets seldom reach the ground as True
rain because they evaporate before reaching the
ground.
12. Which below best describes the solute effect? The water droplets dis-
solve hygroscopic nuclei
and condensation can oc-
cur at relative humidity
less than 100 percent.
13. Heavy showers usually fall from cumulus clouds, True
whereas steady precipitation normally falls from stra-
tus clouds.
14. Large, heavy snowflakes are associated with moist air False
and temperatures well below freezing.
15. Clouds are complex and can have different temper- glaciated
ature zones. The region of a cloud where only ice
particles exist is called ____.
16. Generally, the smaller the pure water droplet, the low- True
er the temperature at which it will freeze.

The growth of a precipitation particle by the collision
of an ice crystal (or snowflake) with a supercooled
liquid droplet is called ____.
18. While the diameter of raindrops can vary widely, most 5 mm
that reach Earth's surface are seldom larger than ____
in diameter.
19. The main difference between a cloud drop and a rain- size
drop is its ____.
20. In a fact that surprises many people, small raindrops slower than; a lesser
fall ____ large raindrops, and have ____ terminal veloc-
ity than/as large raindrops.
21. Atmospheric conditions that produce sleet differ from True
those that produce hail because for sleet to form, sur-
face temperatures must be below freezing, whereas
surface temperatures are typically well above freezing
during hailstorms.
22. The speed of falling cloud droplet increases until the equals the pull of gravity
air resistance ____
23. Which of the following might be mistaken for hail Graupel
because of its appearance and its origin?
24. There are many types of clouds, but not all produce A thick, warm cumulus
precipitation. Which cloud type will only produce pre- cloud.
cipitation by the collision-coalescence process?
25. Rain that falls from a cloud but evaporates before virga
reaching the ground is referred to as ____. One can see
streaks in the sky, and it often has a lovely color.
