Earth’s Interior and Plate Tectonics Quiz Review Name Please answer each question completely to show me that you understand the concepts. Fill in as much as you can from memory, then consult your class materials; ask me for help if needed. 1. Sketch the layers of the Earth on a separate sheet of paper and attach it to the review sheet. Make sure you clearly label the following: outer core, inner core, lithosphere, asthenosphere, upper mantle (specifically showing both parts), lower mantle, crust. Also review the Pizza Slice Earth lab activity and how we determined where to mark the boundaries between the layers. Check out the class’s Earth cross section in the hallway to review the layers. 2. On your Earth’s layers sketch…clearly mark whether each layer is solid, liquid or plastic along with the composition of each layer. 3. How do scientists know about the inner Earth? 4. What are the lithospheric plates? Explain the mechanism behind their movement with an explanation coupled with a sketch. 5. Generally how fast do the lithospheric plates move? 6. What are the two types of crust? What are they made of? 7. Review The Earth’s interior graphs and corresponding table. Did you get all the answers on the table correct? If not, fix your mistakes and turn it back in on quiz day. You will need to understand how to interpret these graphs for the quiz. 8. List the three types of plate boundaries. Which are constructive boundaries vs. destructive? Plate Tectonics Sketches. Explain specifically what happens at each plate boundary. Use your plate tectonics concept map handout as a guide along with the text and notes. 9. Describe what happens at a divergent ocean-ocean plate boundary. Couple your explanation with an arrow diagram sketch. (Make sure you label the subduction zone, the trench, youngest rock and oldest rock.) Give an example of where this occurs on Earth. 10. Describe what happens at a divergent continent-continent plate boundary. Couple your explanation with an arrow diagram sketch. (Is there a subduction zone and trench?) Give an example of where this occurs on Earth. 11. Describe what happens at a convergent ocean-continent plate boundary. Couple your explanation with an arrow diagram sketch. (Is there a subduction zone and trench? If so label them). Give an example of where this occurs on Earth. 12. Describe what happens at a convergent ocean-ocean plate boundary. Couple your explanation with an arrow diagram sketch. (Is there a subduction zone and trench? If so label them). Give an example of where this occurs on Earth. 13. Describe what happens at a convergent continent-continent plate boundary. Couple your explanation with an arrow diagram sketch. (Is there a subduction zone and trench? If so label them). Give an example of where this occurs on Earth. 14. Describe what happens at a transform plate boundary. Couple your explanation with an arrow diagram sketch. (Is there a subduction zone and trench?). Give an example of where this occurs on Earth. 15. Describe what paleomagnetism is and how it supports the theory of sea floor spreading. Couple your explanation with an arrow diagram sketch showing patterns of normal and reversed polarity. 16. For each of the following locations indicate what type specific type of plate boundary each is: Mt. St. Helen’s ____________________________________________________________ Aleutian Islands ____________________________________________________________ Hawaiian Islands ____________________________________________________________ Japanese Islands ____________________________________________________________ San Andreas Fault ____________________________________________________________ Himalayas ____________________________________________________________ Atlantic ocean ridges ____________________________________________________________ Andes Mountains ____________________________________________________________ 17. What is the difference between the theory of plate tectonics and Wegener’s theory of plate tectonics? 18. Review the sea floor spreading lab table and how you derived each of the numbers using the graph. Make sure you understand how you converted the numbers from km to cm and the use of the formula. 19. Review the hot spot lab and how you determined the speed of crustal plate movement. What is the formula to determine speed?
