  1. Ozone Layer Depletion IB SL

  2. What Is It? • The ozone layer is found in the upper stratosphere and its primary function is to filter ultraviolet short-wave radiation that comes from the sun. • Ozone gas absorbs UV radiation. • The 'hole' in the ozone layer was first noted in the 1980's, and is of concern as increased levels of UV radiation can leads to increased levels of skin cancer and eye cataracts.

  3. CFC’s • At first the ozone hole was only found over Antarctica, but it has been becoming larger at a rapid rate, and now affects parts of Chile and Australia. • Although some natural repair occurs each year, it is not sufficient to limit the damage. • The problem is worsened as CFC's are a primary cause of the damage and they remain in the stratosphere for up to 100 years.

  4. Causes Of Ozone Depletion

  5. Effects Of Ozone Depletion

  6. Solutions To Ozone Depletion

  7. Activity Using P206-207 of Geography An Integrated Approach answer the questions below... • What Is Ozone and what does it do? • Why is Ozone dangerous to human health in the troposphere and why may there be a concern to Ozone being depleted in the stratosphere? • What has been done to restrict damage to Ozone Depletion?
