2. Goal:Homework:Warm-up: Boundaries Review Sheet Use models to depict what is occurring at different types of boundaries Pick up one of these sheets and match the picture with the correct letter. I will come around with tape so this can be added to your notebook. 5 minutes End

3. _____ Hot Spot_____ Continental-Oceanic Convergent Boundary ____ Mid-Ocean Ridge _____ Island Arc _____ Oceanic-Oceanic Convergent Boundary ____ & ____ Subduction Zone _____ & _____ Sea Floor Spreading _____ & _____ Divergent Boundary ____ Volcanic Mountains The two types of boundaries NOT pictured: __________________ and _____________________________________

5. Write down what each food represents

7. Divergent Boundary Look at your model from the side: 1.Draw how it looks in cross-section (including the frosting). Label: Midocean Ridge, Oceanic Crust, Asthenospere 2.Describe what happened to the frosting AND the fruit roll-ups. 3.What geological process is being represented in this model? (hint: this is not the type of boundary)

8. You may eat it now!

9. Continental-Oceanic Convergence Look at your model from the side: 1.Draw how it looks in cross-section (including the frosting). Label the trench, oceanic crust and continental crust. 2.Describe what happened to the fruit roll-up and the graham cracker. 3.Explain how this model demonstrates subduction. Include why it is the oceanic plate that subducts in your answer.

10. You may eat the fruit roll up now!

11. Continental-Continental Convergence Look at your model from the side: 1.Draw how it looks in cross-section (including the frosting) 2.Describe what happened to the graham crackers. 3.What landform is this representing?

13. Transform Boundary Look at your model from the side: 1.Draw how it looks in cross-section (including the frosting) 2.Describe what happened to the graham crackers (did they easily move past each other or was there some resistance?) 3.What would occur at this boundary?
