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.

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

• Nitrous oxide

• Carbon dioxide

• Methane

• Chlorofluorocarbons

NGSS.HS-ESS3-5

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.
