    • B. 

      Deforestation

    • C. 

      Increases in smoke and other airborne particles

    • D. 

      A strengthening of the greenhouse effect

  • 2. 
    Greenhouse gasses work by interacting with electromagnetic radiation primarily in what wavelength band?
    • A. 

      Infrared

    • B. 

      Ultraviolet

    • C. 

      Visible

    • D.

      Carbon dioxide

    • B. 

      Methane

    • C. 

      CFC's

    • D. 

      Water vapor

  • 4. 
    How does adding sulfur particles into the upper atmosphere cause cooling?
    • A. 

      By destroying ozone molecules in the upper atmosphere, which reduces the stratospheric greenhouse effect

    • B. 

      By binding with carbon dioxide molecules to make them heavier and fall out of the sky

    • C. 

      By increasing the reflection of solar radiation

    • D. 

      All of the above

  • 5. 
    In addition to melting land ice, what other major factor causes sea levels to rise?
    • A. 

      Increased precipitation into the oceans

    • B. 

      Carbon dioxide and other pollutants adding mass to the ocean

    • C. 

      Land rising due to decreased weight as the glaciers on them melt

    • D. 

      Thermal expansion: water expands in size as it warms

  • 6. 
    The first scientist to hypothesize that an increase in industrial CO2 emissions might increase the planet's temperature was:
    • A. 

      Max Planck

    • B. 

      Svante Arrhenius

    • C. 

      Milutin Milankovic

    • D. 

      Albert Arnold Gore

  • 7.

    • A. 

      El Nino / La Nina cycles

    • B. 

      Changes in solar irradiance

    • C. 

      Volcanic eruptions of sulfates

    • D. 

      All of the above

  • 8. 
    The average amount of solar energy that the Earth receives per square meter of surface area is approximately:

      It is essential for photosynthesis

    • B. 

      Current atmospheric concentrations are high enough to cause respiratory harm

    • C. 

      Dissolving carbon dioxide into aqueous solution forms carbonic acid and reduces pH

    • D. 

      Millions of years ago, carbon dioxide concentrations on Earth were much higher than today

  • 10.

    • C. 

      Increasing air conditioning use in urban areas

    • D. 

      A shutdown of an Atlantic ocean current caused by an influx of fresh water from melted ice

  • 11.
