Ozone Layer

Which of the following is the most common ozone destroying pollutants?

• Chloroflurocarbons

• particular matter

• Nitrogen dioxide

• carbon monoxide

Where is the 'hole' in the ozone layer located?

• Over the United States

• Over Europe

• Over Antarctica

• Around the equator

Though CFC production has been curtailed, the threat to upper atmosphericozone continues because CFCs

• become harmless quickly.

• destroy ozone for only a short time.

• persist but stop destroying ozone.

• persist and continue to destroy ozone for decades.
