APES Unit 9 Review

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in Earth's atmosphere trap heat, preventing it from escaping into space, thus warming the planet.

Front

Name a gas that does NOT contribute to the greenhouse effect.

Back

Oxygen (O2) does not contribute to the greenhouse effect.

Front

Where does 'bad ozone' occur?

Back

'Bad ozone' occurs in the Troposphere.

Front

What is the role of greenhouse gases in Earth's climate?

Back

Greenhouse gases help regulate Earth's climate by trapping heat.

Front

What is the primary component that marine organisms use to form their shells?

Back

Marine organisms primarily use calcium carbonate to form their shells.

Front

Which greenhouse gas is formed by photochemical reactions in the lower troposphere?

Back

Ozone (O3) is formed by photochemical reactions in the lower troposphere.

Front

What are CFCs and their impact on the environment?

Back

Chlorofluorocarbons (CFCs) are man-made compounds that contribute to ozone depletion and have a significant greenhouse effect.

Front

Define photochemical reactions.

Back

Photochemical reactions are chemical reactions that are initiated by the absorption of light, often leading to the formation of new substances.

Front

What is the difference between 'good' and 'bad' ozone?

Back

'Good ozone' is found in the stratosphere and protects us from UV radiation, while 'bad ozone' is found in the troposphere and contributes to air pollution.

Front

What is the significance of carbon dioxide (CO2) in the atmosphere?

Back

Carbon dioxide (CO2) is a major greenhouse gas that contributes to global warming and climate change.
