Total questions: 15
Worksheet time: 10mins
Which of the following might NOT be a reason for past glacial advances?
Milankovitch cycles
atmospheric composition
plate tectonics
ocean circulations
none of these answers
Which of the following matches is correct regarding proxy evidence?
Elevated levels of 18O in ocean sediments means warmer temperatures during that period.
Elevated levels of 18O in ice cores means colder temperatures during that period.
Wider tree rings mean that particular year had climate conditions that weren't favorable for that tree type.
Elevated levels of pine pollen in lake sediments mean that climate conditions were good for pine tree growth during that time.
The amount of carbon dioxide in the atmosphere today:
is higher than ever recorded in history
is lower than ever recorded in history
is about average when comparing it to all historical values
can't be reliably determined by current scientific instruments
An increased number of sunspots:
indicates an active sun with increased solar output
indicates an active sun with decreased solar output
indicates a less energetic sun with decreased solar output
indicates a less energetic sun with increased solar output
indicates a more active sun, but the solar output does not change
Which of the following is NOT a greenhouse gas?
helium
methane
water vapor
carbon dioxide
When higher levels of 18O are found in ocean sediments, this indicates that sediment was laid down during a _____ period in history.
colder than average
warmer than average
wetter than average
drier than average
Which of the Milankovitch cycles is pictured here?
eccentricity
obliquity
precession
ablation
When there is more of the 18O isotope found in ice cores, that indicates:
the global climate was warmer than usual
the global climate was colder than usual
the global climate was drier than usual
the global climate was influenced by a volcanic eruption
What factors control climate change? (Choose ALL that apply!)
changes in the earth-sun relationship, resulting in differences in insolation
changes in the thermohaline circulation, resulting in differences in heat transport
changes in atmospheric composition, resulting in differences in long wave radiation absoprtion
changes in the Coriolis force, resulting in differences in rotation speed of the planet
Which of these is NOT predicted to happen as a result of climate change in the next 80-100 years?
The high latitudes will change more drastically than the low latitudes.
The low latitudes will experience a more dramatic change in climate than the high latitudes.
More extreme weather events (droughts, rain storms, heat waves) will be more common.
Dry places will become drier.
Wet places will become wetter.
When the atmosphere allows short wave energy to pass through but traps long wave energy, this is called:
the thermohaline circulation
the greenhouse effect
atmospheric turbidity
atmospheric eccentricity
The thermohaline circulation:
is most prevalent in the Indian Ocean
is responsible for large die-offs of fish
is responsible for bringing tropical heat toward the poles
has no real impact on weather or climate
Which of the following is NOT a prediction for future ecosystems based on climate change?
Plants and animals will likely shift northward or up mountain slopes.
Growing seasons will likely change, possibly getting longer in the mid-latitudes.
Marine ecosystems will be largely unaffected by climate change, since it's mostly the land that withstands the negative effects.
Mosquitoes and other disease-bearing insects will expand their habitats.
Certain populations may become endangered or extinct due to habitat loss.
Which of the following hazards will be least likely to be influenced by future climate changes?
hurricanes
volcanoes
tornadoes
floods
mass movements (landslides)
Which of the following is a correct pairing related to future effects of climate change on natural hazards?
Thunderstorms are likely to be less common because the planet will be too warm for storms.
Hurricane season is likely to be extended because the sea temperatures will be warm enough for longer.
Everybody is likely to see more rain and precipitation because the warmer atmosphere will hold more water.
Wildfire season is expected to decrease because there will be wetter conditions across the world.
