Greenhouse Gas
Global Warming
Sunspot
CFCs
These graphs show increases in greenhouse
gasses in Earth’s atmosphere. As levels of
greenhouse gasses have increased, the
temperature of Earth’s surface has risen.
Which change has most likely contributed to a
rise in surface temperatures on Earth?
The world birth rate dropped to less than 22
births per 1,000 people per year.
The president of the United States signed a law
that created one of the country’s largest nature
parks.
Farmers increasingly use chemical fertilizers
that allow nitrogen and phosphorous to enter
water sources.
Humans began using work-saving technologies
that release carbon dioxide and methane.
The graph shows the increase in atmospheric
carbon dioxide concentration over several
decades.
Increasing carbon dioxide levels will directly affect
Earth's....
magnetic and gravitational fields.
weather and climate systems.
mantle convection.
rotation speed.
The graph shows changes in carbon dioxide
(CO2) concentrations and surface temperatures
on Earth from the years 1880 to 2000.
Why do carbon dioxide concentrations and
surface temperatures show the relationship seen
in the graph?
because lower carbon dioxide levels mean more
heat is retained in Earth's atmosphere
because higher carbon dioxide levels mean
more heat is retained in Earth's atmosphere
because lower carbon dioxide levels mean less
heat is retained in Earth's atmosphere
because higher carbon dioxide levels mean less
heat is retained in Earth's atmosphere
The graph shows changes in the levels ofatmospheric carbon dioxide over time. What might be one way to reverse the trend shown in the graph?
Increase the rate of deforestation.
Increase the rate of respiration.
Use more fossil fuels.
Plant more trees.
What is the greenhouse effect?
the effect of the Sun's radiation on the
chlorophyll in plant cells
the economic effect of climate change on the
United States' government
the increase of Earth's temperature due to heat
energy being trapped by certain atmospheric
molecules
the decrease in the temperature of Earth's
ocean currents due to atmospheric gases
blocking the Sun's radiation
How is the atmosphere involved in the
greenhouse effect?
Gases in the atmosphere trap and redirect heat
reflected from the surface of Earth.
Heat from the surface of Earth is absorbed by
gases and radiated into space.
Gases magnify the heat of the Sun as it passes
down through Earth's atmosphere.
It transforms light energy from the Sun into
thermal energy that warms the surface of Earth.
Which of the following adds to global warming by
decreasing the amount of carbon dioxide
removed from the atmosphere?
industrialization
burning fossil fuels
deforestation
polluting the oceans
