  1. 1. Ozone Layer By : Sabrina K
  2. 2. Ozone Layer <ul><li>In the late 1920’s chemicals called CFCs. These chemicals were not poisonous to humans, plants and fabrics. Lots of companies wanted to use them in fridges, air conditioners, spray cans and Styrofoam packaging. From 1920’s to the 1970’s billions of cfcs where released into the air. </li></ul>
  3. 3. OZONE LAYER <ul><li>In the 1970’s scientists wondered what happened to all those cfcs after they had been in the air for a while They eventually learned that CFCs could float past the troposphere up into the stratosphere. </li></ul>
  4. 4. OZONE LAYER <ul><li>where UV rays would break them down. The chemicals that make up CFCs, mainly chlorine and fluorine, would float around the stratosphere, breaking up ozone molecules. </li></ul>
  5. 5. OZONE LAYER <ul><li>This was bad, because scientists knew that ozone in the stratosphere protects the Earth from too many UV rays. </li></ul>
