The document defines the greenhouse effect as a process where thermal radiation from the Earth's surface is absorbed by greenhouse gases in the atmosphere and radiated in all directions. It discusses the different layers of the atmosphere and lists common greenhouse gases like carbon dioxide, methane, and ozone. It then explains how increased CO2 from burning fossil fuels contributes to global warming by creating a carbon dioxide cycle and damaging the ozone layer, which protects the Earth from UV rays. The thinning ozone layer and climate change effects from the greenhouse effect include impacts to habitats, agriculture, and more extreme weather.

Greenhouse Effect

2. DEFINITION
 The Greenhouse effect is a process by which
thermal radiation from a planetary suface is
absorbed by atmospheric green house gases, and
is radiated in all directions.

6. Gases
 CO2 - Carbon Dioxide

 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

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
