Weather Test Review Sheet
Name/Period:
This is the start of how to prepare. Be sure to use your notebook and the class webpage to help you
prepare for the test.
Water Cycle: Identify the parts of the water cycle by writing the following terms near the appropriate
arrow: Evaporation, Condensation, Precipitation, and Run off
Explain what happens at each of the following stages in the water cycle. Be sure to explain changes in
energy and states of matter.
1. Evaporation: Water is heated ---by solar radiation. Liquid water is gaining
energy, which changes it from liquid as to a gas (vapor). The less dense water
vapor rises in the atmosphere (troposphere).
2. Condensation: Water vapor (gas) cools; loses energy and slows down; loses so
much energy that it changes from a gas back to a liquid. The liquid clings to
solid particles.
Like the making dew lab-the air became saturated and reached the dew point
3. Precipitation: water droplets or ice crystals that have grown heavy enough to
fall through the air back to the ground.
Can be in solid or liquid form, depending on the temp of the atmo.

Weather Instruments: Name 4 and what they measure.
Instrument
1.Barometure
2.Anemometer
3. Wind Vane
4. Thermometer
5. Psychrometer
What it measures?
Air Pressure
Wind Speed
Wind Direction
Temperature
Relative Humidity
Precipitation-how does each type form?
Rain-cloud is made of liquid water b/c air above 32°F; droplets cling together and fall to earth
as a liquid
Sleet-starts out as rain; falls through a layer of below-freezing air; land as solid pellets
Freezing Rain-start out as ran; falls to ground as a liquid; freezes upon contact with belowfreezing ground/objects.
Snow-air is below-freezing; form in cloud as ice crystals; falls to the ground as a solid.
Hail-Form in cumulonimbus clouds; rise and fall because of updrafts and downdrafts of warm
and cold air, which forms layers of ice
Fronts-What types of clouds are associated with each? What type of weather do they bring?
What is the weather like following the front?
Clouds
Weather at the front
Weather following front
Clouds, precipitation, or
Clear skies, cooler
Cold
Cumulonimbus
thunderstorms-can happen temps, lower humidity
quickly.
Stratus/nimbostratus
Gray skies, drizzle or rain
Warmer temps and
Warm
for a longer period of time higher humidity
(maybe a day or two)
Low clouds, rain possible
Depends on which front
Stationary Stratus/nimbostratus/fog for several days
takes over
Moderate to heavy precip
Occluded
Nimbostratus or
cumulonimbus
Cooler temps and lower
humidity
Define the following:
The temperature at which the air is saturated and condensation begins.
Dew Point
Relative Humidity The % of water vapor in the air compared to the maximum amount the air
can hold at a certain temperature
Air is full of water vapor; rel. humidity = 100%; WV condenses
Saturated

Reading a Weather Map
1. Near which city would you expect to find (circle one for EACH):
a.
A storm or quick downpour
Atlanta
b.
Several hours of drizzly precipitation
Seattle
c.
Several days of overcast, rainy weather Detroit
Denver
Atlanta
Denver
Chicago
Phoenix
Boston
2. What is happening to the air masses at Front B?
a.
A warm air mass is slowly moving up and over a cold air mass
b.
A cold air mass is moving under a warm air mass and pushing it upwards
c.
Neither air mass is moving
3. Atlanta is currently experiencing a ___warm_____ front.
4. Write “true” or “false” on the line for the following statements.
a. _false_____ A cold front is moving towards Detroit.
b. ___false____ Salt Lake City and Phoenix most likely have higher temperatures than Denver
right now.
c. ___true____ The weather system in Chicago will last for a day or two.

Winds Review
1. What causes winds? Differences in air pressure; the unequl heating of Earth.
2. Global Winds-name the 3 wind belts and 2areas of calm
Wind Belts
Areas of Calm
Trade Winds
Horse Latitudes
Prevailing Westerlies
Doldrums
Polar Easterlies
5. In the boxes below, illustrate the four types of LOCAL WINDS. Be sure to represent
whether it is day or night, and COLOR warm air currents RED and cold air currents BLUE.
Heat Transfer: Identify which type of heat transfer.
R-radiation
CV-Convection
CD-Conduction
__CD___George burns his hand touching his tray of tater tots without an oven mitt!
__CV___Angela always keeps the heating vents in her car pointed at her feet because she
knows that her face will feel it soon
___R__Natalie gets an early start on her tan by sunbathing in her living room under the
skylight
___CD/R__Jimmy fries an egg on a rock in Death Valley, CA only to realize he has been scarred
by blistering sunburn
