Location of the large whole in the ozone.

• Antarctica

• Artic

• Iceland

• Africa

Second layer of the atmosphere, extending about 17-48 kilometers above the earth’s surface. It contains a layer of gaseous ozone, which filters out about 95% of the incoming harmful ultraviolet radiation emitted by the sun

• Mesosphere

• Troposphere

• Stratosphere

• Ozone

Which of these sets of three items produce CFCs

• cars, factories, and cardboard

• spray cans, cardboard, insulation

• spray cans, refrigerant, cardboard

• spray cans, refrigerant, insulation

When oxygen gas in the lower stratosphere is struck by this, it splits, leading to the formation of a ozone molecule.
