Ozone Layer

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.

Which statement regarding the decreased level of stratospheric ozone is correct?

• Increased photosynthetic activity has been measured in the phytoplankton around Antarctica

• The largest decrease in the level of stratospheric ozone over the Arctic region occurs between January and April

• Although the Montreal Protocol led to a reduction in the use of CFCs, it will have little effect on stratospheric ozone levels in the long term

• There is no correlation between the incidence of cataracts and skin cancers and the lower level so stratospheric ozone

• The global crop yields of wheat, rice, and corn have increased since the reduction in CFC use
