Stratosphere/Ozone
Layer
-
Ozone layer is in the Stratosphere
-
Stratosphere heated by absorption
of UV light from Sun by Ozone (O3)
-
UV light from "raw" sunlight
would give you a bad sunburn in 10 seconds!
-
Ozone layer very important
to life on Earth
-
Chloroflurocarbons (CFCs)
react with ozone and destroy it
-
CFCs used in refrigerators,
air conditioners
-
Ozone generated naturally
in Stratosphere by sunlight
-
We have dumped so much CFC
into the atmosphere that there is a hole in the ozone layer over antarctica!
-
CFCs are now being phased
out.
