  1. Earth Science Review

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

  3. Explain how similar fossils have been found on both South America and Africa. • Both South America and Africa were once part of the same continent.

  4. Draw a profile of this topo map:

  5. Draw a profile of this topo map: Valley Steeper Lower elevation

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

  7. Describe the way the Theory of Plate Tectonics explains HOW the plates will look in the future • 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. Is this a topo map of a volcano? Why or Why not? depression No, there are no hachures at the top.

  10. Where (how) do volcanoes form?

  11. Where (how) do volcanoes form? • At the boundary where tectonic plates converge (meet) and subduct. trench volcano

  12. Where are the youngest rocks found?

  13. Where are the youngest rocks found? • Mid Ocean Ridge

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

  15. What happens to the age of the rocks as you move away from the mid ocean ridge? • Rocks get older, proving that new sea floor is forming at the ridge. youngest oldest older oldest older

  16. At what point is the hill the steepest?

  17. At what point is the hill the steepest? Point B where the contour lines are the closest.

  18. Describe the formation of a trench

  19. Describe the formation of a trench • Oceanic – continental OR • Oceanic – oceanic convergence with subduction

  20. What is the most significant mid-ocean ridge?Where is it located? Be specific.

  21. Name the most significant mid-ocean ridge.Where is it located? Be specific. • Mid Atlantic Ridge; along the boundary of the South American and African plates and North American and Eurasian Plates.

  22. Describe the formation of a mid-ocean ridge.

  23. Describe the formation of a mid-ocean ridge. • Divergence of oceanic-oceanic plates • Remember : Valley then Rift then Ridge
