First step in smog formation

• ozone forms

• polluting gases react with sunlight

• temperature inversion traps pollution

• cars emit hydrocarbons and nitrogen oxides

Second step in smog formation

• ozone forms

• polluting gases react with sunlight

• temperature inversion traps pollution

• cars emit hydrocarbons and nitrogen oxides

Third step in smog formation

• ozone forms

• polluting gases react with sunlight

• temperature inversion traps pollution

• cars emit hydrocarbons and nitrogen oxides

Last step in smog formation

• ozone forms

• polluting gases react with sunlight

• temperature inversion traps pollution

• cars emit hydrocarbons and nitrogen oxides

What is one effect of a hole in the ozone layer?

• less UV radiation can reach Earth, making it more difficult for essential gases to reach Earth

• more UV radiation can reach Earth, increasing the chance for sunburns

This is an ozone molecule. What happens first in the ozone cycle?

__ radiation hits the ozone molecule
