Ozone is formed in the

• troposhere

• stratosphere

• mesosphere

• thermosphere

Where is the "GOOD" ozone located?

• troposphere

• stratosphere

• mesosphere

• thermosphere

What is the relationship between volcanic eruptions and ozone depletion? (2)

The depletion in the Ozone layer is caused by:

• Carbon dioxide

• Nitrous oxide

• Methane

• Chlorofluorocarbon

Where is the largest '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 atmospheric ozone 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.

When is the ozone hole largest?

• early Antarctic spring

• late Antarctic summer

• early Antarctic winter

• late Antarctic fall

What is the primary cause of the ozone hole?

• Carbon dioxide emissions

• Chlorofluorocarbons (CFCs)

• Methane emissions

• Nitrogen oxides
