The Montreal Protocol banned the use of CFCs. What do they hope this will do for the ozone layer?

• Deplete it completely

• Make the ozone hole smaller

• Make the ozone hole larger

• Thin the layer to allow more gas to escape

Location of the large whole in the ozone.

• Antarctica

• Artic

• Iceland

• Africa

How do CFCs affect ozone production?

• UV radiation frees a chlorine atom, which breaks down ozone.

• Infrared radiation frees a chlorine atom, which breaks down ozone.

• UV radiation frees a fluorine atom, which breaks down ozone.

• Infrared radiation frees a chlorine atom, which breaks down ozone.

How many ozone atoms can a single chlorine atom break down?

• 5,000

• 10,000

• 50,000
