Ozone quiz (PDF 1.5MB)

1. Which of the following are ozone depleting substances?

  1. Chlorofluorocarbons (CFCs)
  2. Hydrofluorocarbons (HFCs)
  3. Hydrochlorofluorocarbons (HCFCs)
  4. Carbon dioxide (CO2)
  5. Both a. and c.

2. What is an ozone molecule formed from?

  1. 3 oxygen atoms
  2. 3 carbon dioxide atoms
  3. 2 carbon dioxide atoms
  4. 2 hydrogen atoms and 1 oxygen atom

3. What is the name of the international agreement committing parties to phasing out ozone depleting substances and phasing down hydrofluorocarbons (HFCs)?

  1. Vienna Protocol
  2. Montreal Protocol
  3. Paris Agreement
  4. Antarctic Convention

4. What is global warming potential (GWP)?

  1. The effectiveness of an air conditioning system. The higher the global warming potential, the better the system at heating a room but the worse at cooling a room.
  2. A measure of the amount of heat trapped in the atmosphere by a certain mass of gas compared to the amount of heat trapped by a similar mass of carbon dioxide.
  3. The net contribution of Antarctic wildlife to synthetic greenhouse gas emissions.
  4. The global temperature rise scientists predict would occur without the phase-down of synthetic greenhouse gases.

5. What is the (approximate) global warming potential (GWP) of hydrofluorocarbon HFC-134a?

  1. 130
  2. 2200
  3. 1430
  4. HFC-134a does not have a global warming potential.

6. Which of the following have ozone depleting substances and synthetic greenhouse gases commonly been used for?

  1. Asthma puffers
  2. Refrigerators and air conditioners
  3. Propellants in aerosol products
  4. All of the above

7. What is the difference between synthetic greenhouse gases and other greenhouse gases?

  1. Greenhouse gases are found in greenhouses, synthetic greenhouse gases are not.
  2. Greenhouse gases occur naturally and through human activity, synthetic greenhouse gases only occur through human activity.
  3. Synthetic greenhouse gases all contain silicon, other greenhouse gases do not.
  4. Both a. and b.

8. How much ozone can one kilogram of halon 1211 destroy?

  1. 1 kilogram
  2. 100 tonnes
  3. 50 kilograms
  4. 50 tonnes

9. Which of the following can still legally be produced in Australia?

  1. Hydrofluorocarbons (HFCs)
  2. Hydrochlorofluorocarbons (HCFCs)
  3. Chlorofluorocarbons (CFCs)
  4. Both a. and b.

10. When do scientists predict the ozone layer will heal and return to pre-1980 levels?

  1. Between the years 2050 and 2065
  2. By the year 2030
  3. Between the years 2080 and 2090
  4. By the year 3000
