TEST Review: Grading Period 4 CCA
Plate tectonics & Topography
1) What is the Theory of Plate Tectonics?
2) For each of the landforms below, draw a diagram and show the movement and the name of the plate boundary that
causes these land features:
Mountains
Deep ocean trench
Mid-ocean ridge
Rift Valley
Earthquakes/Fault
3.) What evidence did scientists use to understand that Earth is broken into plates?
4.) What is the force that drives the movement of the tectonic plates?
5. Describe the steps in history leading to the development of Plate Tectonic Theory.
Old Stuff
6) What is the Theory of Continental Drift?
Be sure to include what Pangaea is; the four evidences offered; who proposed it; and why it wasn’t accepted.
8) Explain Sea Floor Spreading?
What causes it?
Where is the newest/oldest crust found?
What technology led to this theory?
9) Sketch a diagram to show sea floor spreading and label the following items: Mid Ocean Ridge, New Rock, Old Rock,
Trench, Subduction Zone, Mantle
10) Explain subduction.
11) Define weathering and erosion.
12) The puzzle-like fit of the continents is one of the evidences given to explain continental drift (yes, this should be one
of your answers for #6!), but the continents don’t fit together perfectly. Why?
13) Explain how weathering and erosion effect Earth’s surface.
Topography Review
14. Define the following terms: Topography Map, Contour Line, Contour Interval, Hachure Marks, and Index
Contour.
15. What is the contour interval for the map above?
16. Draw a topographic map that shows a steep incline.
17. Draw a topographic map that shows a gentle incline.
18. What direction is Mill River flowing?
19. What is the highest elevation on the map?
20. What is the elevation of point Z?
