Ozone
Chlorofluorocarbon
3
What is global warming potential (GWP)?
how long a GHG stays in the atmosphere
comparisons of the global warming impacts of different gases
The effectiveness of an air conditioning system.
predicted temp. of earth 2050
4
Which is likely to be the most serious problem created by a rise in sea levels?
An increase in seafood production
The need for coastal residents to move
An increase in wetland area
Reduction in annual hurricane precipitation in coastal zones
5
Which could be considered a positive feedback loop contributing to increased global temperatures?
Higher temperatures lead to increased decomposer activity.
An increase in soil loss leads to a decrease in visibility in streams.
Increased CO2 stimulates plant growth.
6
Carbon sequestration is best defined as ______________.
burning fossil fuels and releasing greenhouse gases
the slow warming of the climate
trapping & storing carbon somewhere safe (e.g. underground)
the process of mixing the ocean and air (CO2) with waves
7
Which is a greenhouse gas emitted from natural anaerobic processes typically associated with landfills?
Methane
Ozone
Leachate
CFC's
8
Which is a potential source of natural short-term climate change?
Natural selection
Volcanism
Ecological succession
Earthquakes
9
The concentration of CO2 in the atmosphere in 1958 was 310 ppm & rose to 390 ppm in 2009. What is the percent change?
25%
55%
20%
80%
10
Which gas is the greatest overall contributor to the greenhouse effect?
Methane
Carbon dioxide
Ozone
Nitrous oxide
11
When soot lands on snow and ice, the absorption of thermal energy increases because there is a decrease in
Net primary productivity
albedo
condensation
evaporation
12
Which describes the class of compounds known as chlorofluorocarbons (CFCs)?
They are known to deplete ozone.
Volcanic eruptions release them into the atmosphere.
They were targeted for banning in 1987 as part of the Montreal Protocol
13
Carbon sequestration ________.
splits CO2 to smaller parts reducing warming emissions
has been more dangerous than releasing carbon emissions
captures carbon emissions then releases up in stratosphere
converts CO2 gas to liquid for storage in ocean/underground
14
The difference between the present observed CO2 concentration and the concentration 400,000 years ago is closest to
140 ppm
100 ppm
300 ppm
50 ppm
15
The Kyoto Protocol required countries to...
increase alternative energy sources by 6% in 20 years
cut the world's ecological footprint by 10% in 50 years
cut oil production by one million barrels a day
reduce greenhouse gas emissions to 5.2% below 1990 levels.
16
An increase in tropospheric greenhouse gases will lead to a reduction in heat radiated back to space in the form of
gamma radiation
visible light.
UV light
infrared radiation.
17
Between 400,000 and 100,000 years ago, the highest CO2 concentration was approximately
180 ppm
400 ppm
290 ppm
275 ppm
18
Which is not considered a greenhouse gas?
Carbon dioxide
Nitrogen
Ozone

19
Which is a major cause of increasing greenhouse gas production?
Less efficient energy usage because of a weak global economy
Greater UV radiation exposure because of thinning stratospheric ozone layer
Increasing fossil fuel use because of larger populations, higher affluence
More intense Atlantic hurricane seasons because of global warming
20
Global warming is caused by
tropospheric depletion
ozone depletion
increased GHG in the atmosphere
increased ozone in the stratosphere
21
Which might explain an overall warming trend on Earth's surface?
