Ozone Hole

The thinning of the ozone layer is also known as the

• ozone hole

• ozone gap

• ozone space

• ozone void

What are "holes" in the ozone layer?

• places where the ozone concentrations are lower than under normal conditions, allowing more UV radiation to reach the Earth's surface.

• places where the ozone concentrations are higher than under normal conditions, allowing more UV radiation to reach the Earth's surface.

• places where the ozone concentrations are higher than under normal conditions, allowing lessUV radiation to reach the Earth's surface.

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.
