 Gases
 Causes
 Effects

4. Atmosphere
 Exosphere

6. Gases
 CO2 - Carbon Dioxide
 MH4 - Methane
 O2 – Oxygen Gas
 O3 - Ozone
 N2 – Nitrogen Gas
 Ar – Argon Gas
 H2 – Hydrogen Gas
 He - Helium

7. Increase in CO2
 Increased by the burning of fossil fuels- coal, oil, and
gas
 Too much is harmful to our planet
 Creates a cycle of
Carbon Dioxide
within our atmosphere
 Contributes to the
hole in the ozone
layer

8. Carbon Dioxide Cycle

9. 3-D Image of the Ozone Hole

10. Ozone Layer
 Three oxygen atoms bonded together
 Forms a layer above earth that protects us from
harmful UVA UVB rays
 The ozone hole is a depletion of the ozone in
the atmosphere.

11. What is causing thinning Ozone
Hole?
 Cars
 Factories
 Pollution
 Deforestation

12. Pollutants

13. Effects
 Climate change
 Harms animals’ habitats
 Decrease crop production
 Flooding
 Drought
 Hurricanes
