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 higher carbon dioxide levels mean less
heat is retained in Earth's atmosphere
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
Possible human solutions for limiting global warming and climate change are...
being more energy-efficient
using renewable sources of energy
removing carbon from fossil fuel emissions
all of the above
