  1. Review 8.9ABC Forces that change the earth

  2. Which direction is the river flowing? The river will erode and cut a deeper groove in the land. OR Describe what will happen to the contour lines as the river continues to flow over time.

  3. Will weathering and erosion cause this hill to increase or decrease in elevation? X What is the elevation at the X? 25M

  4. Divergent Plate Boundary what kind of tectonic plate boundaries move away from each other? What land features would you expect to find at this type of plate boundary? Rifts and Ridges such as the Great African rift valley and the mid-Atlantic Ridge Is crust created, destroyed, or neither at a divergent boundary? Created

  5. Transform Plate Boundary what kind of tectonic plate boundaries slide past each other? What would you expect to find at this type of plate boundary? Fault lines and Earthquakes like the San Andreas Fault Is crust created, destroyed, or neither at a transform boundary? Neither

  6. Oceanic-Oceanic Convergent Deep trenches and volcanic islands What are the 3 plate boundaries that move toward each other? Oceanic-Continental Convergent Volcanic Mountain Ranges (Andes Mountains) Continental-Continental Convergent (Himalayas) Give examples of what you would find at each

  7. The continents fit together like a puzzle Evidence of Glaciers in warm climates Coal Deposits in Antarctica Identical fossils on different continents What evidence did Wegener offer to support his theory of continental drift? Sea floor mapping and Satellite Image Technology What later inventions helped create Plate Tectonic Theory?

  8. Lithosphere (Crust and rigid Mantle) Asthenosphere (Upper flowing Mantle) Core (Inner and Outer) What are the different layers of the earth? What causes the tectonic plates to move? Convection

  9. A B C Divergent What type of boundary is at “A”? Oceanic-Continental Conv What type of boundary is at “B”? Where is the newest crust? A Where is the oldest crust? B
