1. Earth Science Review

2. Explain how similar fossils have been found on both South America and Africa.

3. Both South America and Africa were once part of the same continent.

4. Draw a profile of this topo map:

5. Steeper ValleyValley Lower elevation

6. Describe the way the Theory of Plate Tectonics explains HOW the plates will look in the future

7. The Atlantic Ocean will continue to widen, as the Pacific Ocean continues to shrink.

8. Is this a topo map of a volcano? Why or Why not?

9. No, there are no hachures at the top. depression

10. Where (how) do volcanoes form?

11. At the boundary where tectonic plates converge (meet) and subduct. trench volcano

12. Where are the youngest rocks found?

13. Mid Ocean Ridge

14. What happens to the age of the rocks as you move away from the mid ocean ridge?

15. Rocks get older, proving that new sea floor is forming at the ridge. youngestyoungest olderolder olderolder oldestoldest oldestoldest
