  1. The Ozone Layer and the Ozone Hole By: Kate http://troposat.iup.uni-heidelberg.de/TROPOSAT-1/images/ozone_hole_eskes_2000.gif

  2. About the Ozone Layer • The Ozone Layer is 12-30 miles above Earth. It helps protect us from the sun’s harmful rays called ultraviolet rays, the Ozone Layer acts as a shield to Earth and the people of Earth. It absorbs the energy from the UV rays and turns it into heat.

  3. What is Happening to Our Ozone Layer? • Our Ozone Layer is slowly thinning and it is being destroyed. Each Spring, a hole in Antarctica appears and it grows each year , this is called the Ozone Hole. This hole is causing serious medical problems like eye problems. It can cause weakness to the immune system, you have a greater chance of getting skin cancer than you would if there was no hole, and it is very bad for the food chain. http://library.thinkquest.org/11353/ozone.htm

  4. Chlorofluorocarbons( CFCs) • CFCs are chlorofluorocarbons. Many scientists believe that CFCs are destroying our Ozone Layer and creating a hole in Antarctica. CFC gases are pumped through coils on the back of refrigerators and air conditioners. Examples of chlorofluorocarbons are aerosol spray, fire extinguishers, and styrofoam. http://www.ozone-hole.org.uk/images/05a.jpg

  5. Who Found the Hole? • The people who found the ozone hole were named Joseph Farman, Brian Gardiner, and Jonathan Shanklin. They are all BAS scientists. BAS stands for British Antarctic Survey. http://www.theozonehole.com/ozoneholehistory.htm

  6. How Can You Help? • Many people are trying to stop polluting our Ozone Layer and many nations have signed the Montreal Protocol promising to reduce their use of CFC’s. http://thumbs.dreamstime.com/thumblarge_168/1185529709E8OuMO.jpg

  7. Trivia • Who were the three people who found the Ozone Hole? • How many miles above the Earth is the Ozone Layer? • Name one medical problem that the Ozone Hole can cause to your body. http://trishatruly.files.wordpress.com/2008/10/question_mark.jpg

  8. Answers • Jonathan Shanklin, Brian Gardiner, and Joseph Farman • 12-30 miles • Cause weakness to the immune system, cause eye problems, and you have a greater chance of getting skin cancer.
