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

Which of the following best describes the importance of ozone in the stratosphere to life on Earth?

• Ozone reflects X-rays from the Sun back into space.

• Ozone absorbs most of the ultraviolet radiation from the Sun.

• Ozone helps to moderate surface temperature by absorbing CO2 and CH4.

• Ozone increases mutation rates and accelerates evolution in a variety of species.

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

NGSS.HS-PS4-4

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

Which of the following best describes the mechanism of the greenhouse effect in Earth's atmosphere?

• Infrared radiation from Earth's surface is absorbed by gases in the atmosphere.

• Cosmic radiation from deep space is absorbed by gases in the atmosphere.

• Alpha radiation from the Sun is absorbed by water vapor in the atmosphere.

• Ultraviolet radiation from the Sun is absorbed by ozone gas in the stratosphere.

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
