  2. 2.  The ozone layer is aconcentration of ozonemolecules in the stratosphere The ozone layer protects usfrom the Suns UV-B
  3. 3.  It is caused by the release of: chlorofluorocarbons(CFCs) hydrofluorocarbons(HCFCs) other ozone-depletingsubstances (ODS)
  4. 4.  While it is true that volcanoes and oceans release large amounts of chlorine, the chlorine from these sources is easily dissolved in water and washes out of the atmosphere in rain
  5. 5.  In 1978, the use of CFC propellants in spray cans was banned in the U.S. In the 1980s, the Antarctic “ozone hole” appeared and an international science assessment more strongly linked the release of CFCs and ozone depletion
  6. 6.  The answers in order are: yes and no. We cant make enough ozone to replace whats been destroyed, but provided that we stop producing ozone-depleting substances
