Does the Earth Smoke?

1. Take a look at the graph below. How has the Earth’s surface temperature changed over the years?
2. How does a volcanic eruption affect temperature?

3. Research hypotheses about extinct species (such as dinosaurs).

• • Is there a connection between extinct species and volcanic eruptions over millions of years?
  • What research on this topic are you aware of?
  • What are your opinions and assumptions?

4. Present your research in a presentation to share with the class.
