Atmospheric Structure and Ozone Questions

Multiple choice

What is the role of the Arctic in ozone depletion?

  1. It is a major source of chlorofluorocarbons (CFCs)

  2. It is a major sink for chlorofluorocarbons (CFCs)

  3. It is a major source of ultraviolet radiation

  4. It is a major sink for ultraviolet radiation
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The Arctic is a major sink for chlorofluorocarbons (CFCs). This means that it absorbs CFCs from the atmosphere and prevents them from reaching the stratosphere, where they can cause ozone depletion.

Multiple choice

What is the role of North America in ozone depletion?

  1. It is a major source of chlorofluorocarbons (CFCs)

  2. It is a major sink for chlorofluorocarbons (CFCs)

  3. It is a major source of ultraviolet radiation

  4. It is a major sink for ultraviolet radiation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

North America is a major source of chlorofluorocarbons (CFCs). This means that it releases CFCs into the atmosphere, which can then travel to the stratosphere and cause ozone depletion.

Multiple choice

What is the role of South America in ozone depletion?

  1. It is a major source of chlorofluorocarbons (CFCs)

  2. It is a major sink for chlorofluorocarbons (CFCs)

  3. It is a major source of ultraviolet radiation

  4. It is a major sink for ultraviolet radiation
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

South America is a major sink for chlorofluorocarbons (CFCs). This means that it absorbs CFCs from the atmosphere and prevents them from reaching the stratosphere, where they can cause ozone depletion.

Multiple choice

What has been the impact of the Montreal Protocol on ozone depletion?

  1. It has led to a decrease in the production and use of chlorofluorocarbons (CFCs)

  2. It has led to a decrease in the concentration of chlorofluorocarbons (CFCs) in the atmosphere

  3. It has led to a decrease in the rate of ozone depletion

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The Montreal Protocol has led to a decrease in the production and use of chlorofluorocarbons (CFCs), a decrease in the concentration of chlorofluorocarbons (CFCs) in the atmosphere, and a decrease in the rate of ozone depletion.
