Study Guide for Plate Tectonics Assessment Below are questions related to the content you need to know for the post assessment for HS-ESS2-1 and HS-ESS2-3. 1. What is the differences between continental-continental, continental-oceanic, and oceanicoceanic collisions? Northward movement of India into Eurasia 2. What is a rift zone? 3. What is the difference between divergent, convergent, and transform boundaries? 4. What is a Curie Point? 5. What is a hot spot? 6. How do magnetic reversals relate to seafloor spreading? Linear magnetic patterns associated with mid-ocean ridges are configured as normal and reversed magnetized strips roughly parallel to the ridge. 7. You need to know what “modern” evidence is used to support the Theory of Plate Tectonics. Hot spots, ocean floor drilling, and paleomagnetism 8. What type of plate boundary is the Red Sea? 9. What formed the Hawaiian Islands? Shield volcanoes fed by a long-lived hot spot below the Pacific lithospheric plate. 10. What type of rock forms the Oceanic Plates? What type of rock forms the Continental Plates? 11. Where does new ocean crust form during seafloor spreading? Divergent boundaries by submarine (underwater) eruptions and intrusions of basaltic magma. 12. Where does old oceanic crust get removed? Subduction zones along plate boundaries… 13. What forms ocean trenches? Sinking of oceanic lithosphere into the mantle at a subduction zone 14. An important fundamental assumption underlying the plate tectonic theory is that Earth’s __diameter_________________ has remained constant over time. 15. How did Mount St. Helens and the other Cascade volcanoes on the North-western coastline of the United States form? Young, active, stratovolcanoes built on a continental margin above a subduction zone where ocean meets continent. 16. How did the volcanoes and rift valleys of East Africa form? Continental rift alowhich parts of the African continent are beginning to slowly separate. 17. How do Island Arcs form? Convergent boundary on a volcanic island arc above a northwardsubducting Pacific plate. 18. Where did the Aleutian Islands form? Convergent boundary on a volcanic island arc above a northward Pacific plate. 19. What is the most common way of finding out where the plate boundaries are located? Lines of earthquake epicenters most effectively outline the edges of the lithospheric plates. 20. What ocean are ocean trenches most abundant? 21. Who first related the symmetrical magnetic patterns in seafloor basalts to seafloor spreading at a mid-ocean ridge? 22. What did the results of the Deep Sea Drilling Project clearly justify? 23. The west coast of South America is what kind of plate boundary? 12/8/16 Thursday Get your study guide out! We are reviewing for the semester exam.
