10) In what type of clouds does hail usually form?
Cumulonimbus
37) Frost forms here
D
27) Measures in kts
Anemometer
34) Freezing rain becomes solid here
D
46) List and describe the purposes of at least three weather instruments or weather-data collecting devices from the chapter that were not already mentioned on this test.
Thermographs measure temperature at a constant rate over time. Psychrometers measure humidity. Weather satellites measure cloud cover and temperature.
7) What is the prefix used when naming mid-altitude cloud types?
Alto-
32) Fog develops here
C
43) Nimbus-type clouds often bring rain.
True
36) Hailstones form by convection in this environment
E
15) The dew point is the temperature at which the relative humidity is equal to ________________________.
100%
24) What are clouds made of?
Clouds are made of water droplets or ice crystals that have coalesced or sublimated around a particle of dust or some other condensation/freezing nucleus.
33) Rain forms in these environments (two answers)
B & E
16) Liquid water below the freezing point is called _____________________________.
Supercooled water
31) Snow forms in this environment (two answers)
B & E
9) Which one of the following words or phrases is not associated with cirrus clouds?
Supercooled water
17-18) The three basic shapes of clouds are flat layers or sheets called stratus, piles called ___________________ and wispy curls called __________________ .
cumulus, cirrus
22) What do the two common reference points of the Fahrenheit and Celsius temperature scales relate to?
Upper measuring point is the boiling point and the lower is the freezing point.
47) How is a condensation nucleus different from a freezing nucleus?
Both start from a microscopic particle like dust, pollen, smoke, or salt in the atmosphere. If the dew point is above the freezing point of water, the liquid droplets will form a cloud droplet from the condensation nucleus. A freezing nucleus is the vapor depositing as ice crystals on the nucleus when the dew point is below the freezing point of water.
35) Sleet forms in this part of the atmosphere
C
45) Discuss some of the advantages and disadvantages of harnessing wind power in exercising dominion over the earth.
Winds farms, if strategically located, can provide electricity at a fraction of the cost compared to many other sources and doesn't cause pollution. However, large wind turbines can be noisy, dangerous for birds, and hazardous to humans if it malfunctions.
