  2. 2. INTRODUCTION OF THE OZONE LAYER INTRODUCTION OF THE OZONE LAYER THE OZONE LAYER IS A REGION IN THE STRATOSPHERE, BETWEEN SEVENTEEN AND TWENTY-FIVE KILOMETRE ABOVE THE EARTH ‘S SURFACE THE OZONE LAYER CONTAINS HIGH CONCENTRATION OF OZONE MOLECULES , O3 THAT ABSORB ULTRAVIOLET RADIATION AND SHIELD ORGANISMS FROM ITS DAMAGING EFFECTS
  3. 3. THINNING OF THE OZONE LAYER THINNING OF THE OZONE LAYER THE THINNING OF THE OZONE LAYER IS MAINLY DUE TO CHLOROFLURO CARBONS (CFC). ONCE IN THE STARTOSPHERE, CFC ARE BROKEN DOWN BY ULTRAVIOLET RAYS. THESE CHLORINE RADICALS BRAKE DOWN OZONE MOLECLUES , O3 IN A CHAIN REACTION. AS A RESULT , THE HIGHLY REACTIVE CHLORINE RADICALS ( CI ) ARE RELEASE.
  4. 4. THE EFFECTS OF OZONE DEPLETION THE EFFECTS OF OZONE DEPLETION EXCESSIVE ENTERING OF ULTRAVIOLET RADIATION TO THE EARTH ‘S SURFACE LEAD TO HIGHER RISK OF SKIN CANCER , CATARACTS AND SUNBURNS DUE TO PROLONGED EXPOSURE TO ULTRAVIOLET RADIATION REDUCE THE NUTRIENT CONTENT AND CROP YIELDS DUE TO ULTRAVIOLET RADIATION LEAD TO THE INCREASE OF THE EARTH ‘S TEMPERATURE

  9. 9. THE THINNING OF THE OZONE LAYER HAVE SOMETHING IN COMMON WITH GREENHOUSE EFFECTS
  10. 10. The picture in the above slide is about iceberg which is a very huge ice that contain most of the sea water.If there is a hole in the ozone layer than the iceberg will melt and will cause this:
  11. 11. WORDS HARD TO UNDERSTAND OZONE HOLE • A term invented to discribe a region of a very low ozone concentration above the antartic that appears and disappears with each austral (southern hemisphere) summer. CLOROFLUOROCARBON (CFC) • A family of compounds consisting of carbon,fluorine and chlorine.
  12. 12. ULTRAVIOLET RADIATION • A FORM OF ELECTROMAGNETIC RADIATION WITH WAVELENGTHS JUST LESS THAN THOSE OF VISIBLE LIGHT ( FOUR TO FOUR HUNDRED NANOMETERS , OR BILLIONTHS OF A METER ) RADIATION • ENERGY TRANSMITTED IN THE FORM OF ELECTROMAGNETIC WAVES OR SUBATOMIC PARTICLES
  13. 13. QUESTIONS & ANSWERS 1.What is the meaning of ozone hole? A term invented to discribe a region of a very low ozone concentration above the antartic that appears and disappears with each austral (southern hemisphere) summer. 2.What is the meaning of clorofluorocarbon? A family of compounds consisting of carbon,fluorine and chlorine. 3.What is the meaning of ultraviolet radiation? A form of electromacnetic radiation with wavelengths just less than those of visible light ( FOUR TO FOUR HUNDRED NANOMETERS , OR BILLIONTHS OF A METER ) 4.What is the meaning of radiation? Enegy transmitted in the form of electromacnetic waves or subatomic particles.
