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.

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

• Chloroflurocarbons

• particular matter

• Nitrogen dioxide

• carbon monoxide

The ozone destroying pollutants primarily comes from air conditioner coolants, refrigerator coolant, aerosol spray, and plastic foam.

• true

• false

Layer of gaseous ozone in the stratosphere that protects life on earth by filtering out most harmful ultraviolet radiation from the sun

• Greenhouse Gases
• Troposphere
• Stratosphere
• Ozone Layer

Which agreement allowed for a reduction, and eventual elimination, of CFC production and use?

• Montreal Protoccol
• Kyoto Protoccol
• Paris Agreement
• Yo MaMa

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.

Depletion of ozone layer is a concern because it normally absorbs ____% of the sun's UV radiation. 

• 50
• 75
• 89
• 99
