3.  Ozone is a molecule  made of 3 atoms of oxygen  Ozone is a bluish gas  Ozone helps absorbs harmful UV radiation from the sun

4. LLayer of ozone found in the stratosphere DDiscovered in 1913 by French physicists Charles Fabry and Henri Buisson OOzone layer created by oxygen-ozone cycle

5.  Protects organisms from harmful UV rays.  keeps the surface from heating up

6.  3 types of UV rays  UV A rays are the least harmful  UV B rays can cause skin cancer/genetic problems  UV C rays completely are blocked

7.  Deterioration of ozone layer  CFCs are the main agents  Chlorine and Bromine  More UV rays reach the surface

8.  Without the ozone layer surface heats up  Change climate  More UV rays reach Earth  Cause more genetic diseases  Effect ecosystems

9.  ODS are Ozone depleting substances  CFC are the main chemical that breaks down Ozone Layer  HCFC and PCB and halons  Volcanic Activity, Green House Gasses, and Sun Spot cycles

10.  Decrease the use of products that contain CFC  Planting Trees  Avoid Deforestation  Check the leakage of vehicle air  Decrease emissions of chlorine, bromine,  Raise awareness of ozone layer depletion  Help pass laws that regulate emissions of harmful pollutants

11.  Vienna Convention for the Protection of the Ozone Layer  Montreal Protocol  Annual RAD reports  Phase-out Management Plans
