  • Q1
    is important to the evolution of life on Earth and the continued health and survival of life on Earth
    stratospheric ozone layer
  • Q2
    is caused by anthropogenic factors, such as chlorofluorocarbons (CFCs), and natural factors, such as the melting of ice crystals in the atmosphere at the beginning of the Antarctic spring
    Stratospheric ozone depletion
  • Q3
    it increases the UV rays that reach the Earth's surface
    how does a decrease in stratospheric ozone affect UV radiation on Earth?
  • Q4
    can lead to skin cancer and cataracts (eye damage) in humans
    health impacts of UV radiation
  • Q5
    A family of organic compounds whose properties make them ideal for use in refrigeration, air-conditioning, and aerosols; cause ozone depletion
    Chlorofluorocarbons (CFCs)
  • Q6
    chlorine atoms contained in the compounds are highly reactive; they interact with Ozone (O3) by stripping off one Oxygen molecule, leaving behind O2.
    How do CFCs and HCFCs destroy ozone?
  • Q7
    by replacing ozone-depleting chemicals with substitutes that do not deplete the ozone layer such as Hydrofluorocarbons (HCFs)
    How can ozone depletion be mitigated (reduced)?
  • Q8
    have a high Global Warming Potential and are thousands of times more powerful as a greenhouse gas than carbon dioxide
    Even though HCFs do not deplete the ozone-layer, they are still an environmental concern because they
  • Q9
    carbon dioxide
    the principal greenhouse gases

    water vapor
  • Q12

    nitrous oxide
  • Q13
    See image
  • Q14
    it doesn't contribute significantly to global climate change because it has a short residence time in the atmosphere (weighs more than gas)
    water vapor as a greenhouse gas
  • Q15
    GWP of 1; is used as a reference point for the comparison of different greenhouse gases and their impacts on global climate change
    global warming potential of carbon dioxide
