GEO CHAPTER 3
what is another name for the ozone layer?
ozonosphere
What is ozone?
Molecule made of 3 oxygen atoms
How much of suns UV reaches earth's surface?
a little
What would happen to the oxygen atoms in ozone if the ozone layer were completely destroyed by UV radiation?
The oxygen atoms would be bound together in pairs.
How do CFCs cause ozone depletion?
UV breaks down CFCs, molecules containing chlorine. Chlorine then breaks 1 oxygen atom away from ozone, leaving behind a paired oxygen molecule
How is ozone formed in stratosphere?
UV radiation breaks apart molecules made up of paired oxygen atoms. Individual oxygen atoms bond with paired oxygen molecules to form ozone.
