8.2 Mass Extinctions Systems Diagram

  • Page ID
    1. Choose one example of a mass extinction event from the graph on the last page. Research the event and determine who, what, where, why and how. Use the attached Research Template to guide your search.
    2. Construct a systems diagram to illustrate the effect of the extinction on the Earth systems and subsystems. (Include atmosphere, hydrosphere, geosphere, biosphere, space sphere). Write a description or caption to explain your systems diagram.
    3. Write a brief reflection: How might human activities influence rates of extinction? To what degree can our activities delay or prevent the extinction of any species, including our own?
