- 4. Description about Ozone Layer The Ozone layer is mainly found in the lower portion of the Stratosphere, from approximately 20 to 30 Kilometers or 12 to 19 Miles above Earth, although it’s thickness varies seasonally and geographically.
- 5. The Inventor of Ozone Layer Charles Fabry Two French Physicist Henry Buisson
- 6. 1. Joseph Farman 2. Brian Gardiner 3. Jonathan Shanklin In 1984, these three Antarctic Survey Scientists discovered a recurring Antarctic Ozone hole. In May, 1985, They first reported in Paper in Nature
- 7. Dr. Susan Salomon In 1986, He was invented that the Chlorine is main cause of destroying Ozone Layer.
- 8. Creation of Ozone Layer at Stratosphere • AtThermosphere, the huge reduction of Sunlight is received, and the some reduction comes at stratosphere to create O from O2 . Now these powerful O attacked many O2 atoms and create the Ozone(O3). Reaction:-
- 9. METHOD OF EROSION THE OZONE LAYER CFCl3 = Frion-11 CF2Cl3 = Frion-12 CClF2CClF2 = Frion- 114
- 10. EROSION OF OZONE ATOM
- 11. IMPORTANCE OF OZONE LAYER Ozone Layer is called the Umbrella of Earth or Security guard of Earth. It eat the 99 percent of UV ray and give us a fresh and normal sunlight. We are get free from the harmful effect of UV ray.
- 12. Effects of ozone depletion
- 13. Effects on Human – Sunburn – Sun-damaged skin – Cataracts – Snow blindness – Skin Cancer
- 15. Protecting the ozone layer – To reduce ozone depletion, we must stop producing all ozone-depleting chemicals. – A big step towards doing this way the Montreal Protocol(1987). The most widely ratified treaty in UN history. If followed, Ozone predicted to recover by 2050.
