9.1-9.4 quiz review

Which of the following is a primary cause of stratospheric ozone depletion?

• Carbon dioxide emissions

• The release of chlorofluorocarbons (CFCs)

• Increased levels of nitrogen oxides

• Absorption of ultraviolet radiation by ozone

What role do polar stratospheric clouds play in ozone depletion?

• They absorb excess UV radiation, reducing its impact on ozone

• They trap heat, preventing chemical reactions that destroy ozone

• They provide surfaces for chemical reactions that release chlorine, which destroys ozone

• They increase the formation of ozone by trapping oxygen molecules

Which of the following greenhouse gases has the highest global warming potential (GWP) per molecule?

• Carbon dioxide (CO₂)

• Methane (CH₄)

• Nitrous oxide (N₂O)

• Chlorofluorocarbons (CFCs)

The greenhouse effect is primarily caused by:

• The absorption and re-radiation of infrared radiation by greenhouse gases

• The reflection of ultraviolet radiation by greenhouse gases

• The increase in atmospheric oxygen levels

• The movement of warm ocean currents
