Which of the following best exemplifies global collaboration for a sustainable environment? (Getting rid of CFCs)

• The Antarctic Treaty of 1961

• The Clean Air Act of 1972

• CERCLA (Superfund)

• The Montreal Protocol

The second step of ozone formation involves atomic oxygen combining with what molecule?

• CO2

• O2

• NO2

• 2H2O

The breakdown of CFCs in the atmosphere is caused by UV rays.

• True

• False

Which of the following is a greenhouse gas that comes only from human sources?

• Nitrous oxide

• Carbon dioxide

• Methane

• Chlorofluorocarbons

Although levels of CFCs in the atmosphere are much lower than those of CO2 , CFCs are still potent greenhouse gases because they

• remain in the atmosphere for only a brief time

• lack natural sources

• are much more efficient at absorbing thermal radiation

• are more difficult to remove from smokestacks and tailpipes

All of the following gases have been implicated in contributing to the increase in global temperature via the greenhouse effect EXCEPT

• CFC's

• O2

• N2O

• CO2

Why is water vapor not considered a significant contributor to global climate change?

• The concentration of water vapor is very low compared to the other gases.

• Water vapor is inefficient at absorbing heat and does not absorb much of the infrared spectrum.

• Trees and other organisms naturally release water vapor during the process of decomposition.

• Water vapor has a relatively short residence time in the atmosphere.
