• Carbon footprint

• carbon tax

• carbon offset

• carbon sequestration

What is the greenhouse effect?

• warming of the earth due to gases such as carbon dioxide and methane in our atmosphere

• cooling of the earth due to gases in our atmosphere

We need the natural greenhouse effect for Earth to be habitable.

• True
• False

Which of the following sets of evidence supports global warming?

• CO₂ levels rising

• Sea levels rising

• Glacier mass decreasing

• All of the above

Which environmental concern is most associated with burning of fossil fuels?

• global climate change

• ozone layer destruction

• pollution of ocean waters

• decrease in atmospheric carbon dioxide

Trees help the Earth because...

• ...they absorb huge amounts of Carbon Dioxide (CO2) from the air and release oxygen back into it.

• ...they absorb huge amounts of oxygen from the air and release Carbon Dioxide (CO2) back into it.

• Methane

• Nitrogen Oxide

• All answers are correct

The graph below shows CO2 emissions and temperatures from 1909 to 1949.  What conclusion is best supported by the graph?

• There is no relationship between carbon dioxide concentrations and temperatures
• As carbon dioxide concentrations increase, temperatures increase
• As carbon dioxide concentrations increase, temperatures decrease
• As carbon dioxide concentrations decrease, temperatures increase
