Jeopardy
RULES
1. The team who answers correctly wins the
point value of the question.
2. There are two daily doubles available.
3. If a team answers incorrectly for a daily
double, then that team will lose the
number of points that the question was
worth, and any other team can “ring in”
by holding up their answer at that point.

Final Jeopardy
The Air for 100
Earth’s ozone layer protects us from
_________ radiation.
ultraviolet
The Air for 200
Which layer of the atmosphere is the layer
in which we live and also contains Earth’s
weather?
The troposphere
The Air for 300
As you go lower in altitude, air pressure
will…
increase.
The Air for 400
What are the two most abundant gases in
the atmosphere? What percent of our
atmosphere do these two gases make up?
Nitrogen (78%) and oxygen (21%)
Other gases- 1%
The Air for 500
What is the major source of air pollution?
Describe how photochemical smog forms.
Burning fossil fuels.
Sunlight causes a reaction with pollutants in
the air create a brownish haze called
photochemical smog.
Storms for 100
What type of cloud indicates a thunderstorm
is approaching? Give an example of a state
that can receive very bad thunderstorms
where tornadoes can form (in Tornado
Alley).
Cumulonimbus clouds; Oklahoma, Kansas,
Texas, Nebraska, Iowa
Storms for 200
What type of low-lying clouds indicate that
some light rain or drizzle may be on its
way?
Stratus clouds
Storms for 300
How does a cold front form?
Cold air moves toward warm air and forces
the warm air higher in altitude.
Storms for 400
How does lake effect snow form?
Cold, dry air picks up moisture from the
Great Lakes and dumps it as snow over
land.
Storms DAILY DOUBLE!!!
Hurricanes form over what type of water?
Why do they form over this type of water?
Warm, ocean water b/c the storm draws
the moisture up from the warm water.
Warm water vaporizes easier into a gas.
Heating the Atm. for 100
Energy that heats the air is called
__________ radiation.
infrared
Heating the Atm. for 200
Greenhouse gases ________ heat and may
contribute to global _________.
trap; warming
Heating the Atm. for 300
Heat transfer between the ground and the
layer of air the ground is in contact with is
called _________. The main method by
which the troposphere is heated is by
___________.
Conduction; convection
Heating the Atm. for 400
Is the air warmer just above the ground or a
few feet up on a sunny day with no wind?
Explain your answer.
The air is warmer just above the ground b/c
the ground radiates heat back into the
atmosphere.
Heating the Atm. for 500
Explain how convection heats the
troposphere. Include the relative density of
each air mass in your answer.
Denser cool air sinks, becomes heated from
the infrared radiation from Earth’s
surface, then rises b/c it’s less dense. This
cycle continues.
Winds for 100
Winds flow because air moves from
________ to ________ air pressure
Higher to lower air pressure
Winds for 200
What is the Coriolis effect?
The effect of the Earth’s rotation on
winds that makes them curve.
Winds for 300
Most air masses and storm systems move
__________ to ________. What causes air
masses and storms to move this direction in
the United States?
West to East; Prevailing Westerlies and
Jet Streams
Winds for 400
Why do sea breezes occur?
The air moves from the sea because it
heats up slower than the land during the
day.
Winds
DAILY DOUBLE!!!
Which city will have a smaller average
yearly temperature change: San Diego,
CA or Boston, MA. Explain your
answer.
San Diego b/c cool, humid air from the
ocean blows West to East into the city,
while in Boston air is moving to the
city from over land.
Water in the Atm. for 100
A low-pressure center is called a _________
and usually brings ________ weather.
Cyclone; cloudy and rainy
Water in the Atm. for 200
What’s the difference between evaporation
and condensation? Which one is caused by
heating? Which one is caused by cooling?
Evaporation- liquid to a gas (via heating)
Condensation- gas to a liquid (via cooling)
Water in the Atm. for 300
When do you sweat more: when the
humidity is high or low? Explain why.
High b/c the air cannot hold much
more water vapor, so your sweat
evaporates slowly.
Water in the Atm. for 400
Describe each type of air mass below in terms
of the weather they bring to areas of the United
States: maritime polar, maritime tropical,
continental polar, continental tropical.
Maritime polar- cold and humid
Maritime tropical- warm and humid
Continental polar- cold and dry
Continental tropical- warm and dry
Water in the Atm. for 500
Suppose you were wearing glasses outside
on a very cold winter day. What will
happen to the glasses when you go back
inside your home? If a substance forms on
them, then where did this substance come
from?
They will fog up b/c water vapor
condensed onto them from the air.
Weather Forecasts for 100
What instrument is used to measure air
pressure? What does a drop in air pressure
indicate in terms of weather.
A barometer; stormy weather may be on
its way.
Weather Forecasts for 200
Weather forecasts are more accurate
because meteorologists are now able to
gather more weather _______ and input this
data in a ________ to predict the weather.
Data; computer
Weather Forecasts for 300
What type of weather technology would
better enable a meteorologist to follow the
path of a thunderstorm?
Doppler Radar
Weather Forecasts for 400
List 3 specific weather technologies that
have caused an improvement in the
collection of weather data.
Computers, Doppler Radar, Weather
Balloons, Weather Satellites, Automated
Weather Stations
Weather Forecasts for 500
Draw a cold front heading North and an
occluded front heading West. Then draw a
stationary front.
Cold front- triangles facing
upward/North.
Occluded front- alternating triangles and
half-circles all facing left/West.
Stationary front- triangles and halfcircles facing opposite directions.
Winds
Suppose you heard there are some storms
throughout PA and wanted to know if any
would be coming into Bellefonte. What
direction should you look to see if a storm is
approaching? Why?
West, b/c winds move storms West to East
in the U.S.
