3. Aim #79: How have air pollutants affected the atmosphere?

4. 1) Carbon Dioxide in the Atmosphere:
The amount of carbon dioxide in the atmosphere has
been rising.

5. 2) How do we contribute to the increase of carbon dioxide in the atmosphere?
Burning of fossil fuels
Deforestation
Cow flatulence
(methane)
CO2, SO2, NO2 +

6. 3) How does Deforestation cause an increase in atmospheric carbon dioxide?
Glucose
H2O + O2
CO2
Increased CO2 in the atmosphere

7. 4) What does increased levels of carbon dioxide in the atmosphere cause?
Increased levels of CO2 in the atmosphere trap the
heat that would normally radiate back into space.
This increase in earth’s temperature is called:
Global Warming

8. BrainPop: Climate Change

9. 5) What are some of the detrimental effects of Global Warming?
Melting of the polar ice caps, leading to a rise in sea
level and flooding in many coastal areas.

10. 6) Disruption of the Carbon/Oxygen Cycle:
Deforestation &
Fossil Fuel Burning

12. 7) What are chlorofluorocarbons?
Found in aerosol cans
Refrigerator Emissions
Air Conditioner Emissions
CFC’s

13. 8) What is the problem with using CFC’s?
They create holes in the ozone layer around earth.
This layer prevents UV radiation from reaching earth.

14. 9) How can UV radiation affect living things?
Mutations
Cancer

15. 10) Global Warming vs. Ozone Layer Depletion
