Answers
1
How would a rise in average global ocean water temperature affect sea level?
decrease global sea level
make sea levels fluctuate b/w extreme highs and lows
increase global sea level
the effects are impossible to predict
2
Global winds are caused by _____, local winds are influenced more by_____.
regional geography; Earth's climate
atmospheric convection cells; regional geography
air pressure differences; regional geography
atmospheric convection cells; Earth's climate
3
Compare temperate forests to locations of grasslands.
forests are located at lower altitudes
forests are located in areas of higher humidity
all of these
forests are located in the interiors of continents
4
Which data would help a scientist determine the existence of a microclimate in a small area?
latitude, longitude, and elevation of the area
long term average weather conditions of the area
temperature, precip, humidity, and wind speed on one day
proximity of the area to a major ocean current
5
How do atmospheric circulation cells affect climate?
transfer heat energy from higher to lower latitudes
transfer heat energy from continents to oceans
transfer heat energy from lower to higher latitudes
transfer heat energy from oceans to continents
6
How do conditions in the equatorial Pacific Ocean change during El Nino?
deep currents become unusually warm
deep currents become unusually cool
surface currents become unusually cool
surface currents become unusually warm
7
Which process has the greatest effect on Earth's weather?
Coriolis effect
water cycle
carbon cycle
butterfly effect
8
If absolute humidity stays the same, but air temp increases, the relative humidity will ____.
increase
remain constant
decrease but remain above 0%
fall to 0%
9
How does solar radiation warm the atmosphere?
surface reflects solar radiation back into atmosphere
all of these
surface absorbs solar radiation
atmosphere absorbs solar radiation
10
What causes lightning to form in clouds?
latent heat released during the condensation of water vapor
all of these
friction of water molecules moving up and down in cloud
friction of ice particles moving up and down in cloud
11
Would winds stop if the sun were able to heat Earth's atmosphere uniformly?
No; diff in density & air pressure would produce jet stream
No; Earth's rotation would still produce winds
No; differences in local geography would produce local winds
Yes; cause of all wind is the differential heating from sun
12
How do the position and shape of a jet stream affect the weather?
shape of jet stream is unrelated to weather patterns
flat jet stream separates air mass= severe weather
large dips in jet stream cause air mass mix=severe weather
large dips in jet stream cause air mass mix=calm weather
13
How have human-caused emission of CO2 influenced average global temperature changes?
emissions have caused temps to swing to high & low extremes
emissions have increased average global temperatures
emissions have not affected temps
emissions have decreased average global temperatures
14
Which characteristic of a region affects the region's climate?
type of bedrock
shape of landforms
type of soil
diversity of organisms that live there
15
What is the difference b/w continental climate and temperate climate?
interiors of continents have milder summers & winters
interiors of continents less likely to have severe weather
interiors of continent receive more precip in a year
interiors of continents have hotter summers & colder winters
16
What is the greenhouse effect like on Venus?
moderate amount of greenhouse gases = temps that allow life
small amount of greenhouse gases = temps too low for life
small amount of greenhouse gases = extreme temp ranges
high level of greenhouse gases keeps temps too high for life
17
How does ozone protect human health?
filtering out harmful UV radiation
destroying greenhouse gases in the atmosphere
chemically reacting w/pollutants
adding oxygen to the bloodstreams of humans who inhale it
18
Why should we develop alternative energy to replace fossil fuel burning plants & engines?
all of these
alt energy will help mitigate the problem of global warming
gases emitted by burning fossil fuels cause health issues
fossil fuel resources are diminishing quickly
19
What would be most useful in predicting the direction of a thunderstorm?
thermometer
barometer
radar
anemometer
20
What is the relationship b/w tree rings & average weather conditions when the ring formed?
wider rings form in warmer, wetter years
wider rings form in drier, cooler years
narrower rings form in wetter years
narrower rings form in warmer years
21
A warm ocean current will make the climate of nearby land____.
warmer and wetter
warmer in summer and cooler in winter
cooler and wetter
warmer and drier
22
Which would NOT be part of a weather description?
air temperature
tide height
air pressure
wind speed
23
Which part of the atmosphere naturally experiences a temperature inversion?
troposphere and mesosphere only
tropopause & stratopause only
none of these
stratosphere only
24
Adiabatic cooling results from which characteristic of the atmosphere?
altitude increases, air pressure decreases
altitude increases, air pressure increases
altitude increases, wind speed increases
altitude increases, wind speed decreases
25
What is one way that topography can affect climate?
solar radiation increases around the equator
adiabatic cooling occurs over a mountain chain
temperature of atmosphere increases w/altitude
stratospheric ozone forms over major cities
26
On a day w/high relative humidity, what is true about the dew point temperature?
dew point is relatively close to current temperature
dew point is more than twice current temperature
dew point is less than half current temperature
dew points fluctuates between two extremes
27
Thunderstorm is moving over tropical waters toward land; is this a hurricane?
Yes; definitely a hurricane
No, hurricanes are never over water
probably not; hurricanes begin over land and move out to sea
probably not; hurricane not a single storm
28
Why are computer models useful in predicting climate change?
can analyze huge amounts of data
can fill in gaps in data with best guesses
can determine what data support conclusion of global warming
can be easily created with only a few pieces of data
29
What data would be helpful in assessing climate in a region?
amount of precip during the worst storm of the year
amount of solar radiation reaching ground on summer solstice
average monthly temp & precipitation over a year
temp, precip, air pressure, humidity, wind speed on one day
30
What is the primary cause of Earth's current trend toward global warming?
decrease in the size of the polar ice caps
decrease in the concentration of stratospheric ozone
increase in amount of radiation being released by the sun
increase in concentration of greenhouse gases in atmosphere
