Let’s take a look at some plate boundaries using the one and only… Find Ms. Crownhart’s website, Geology Link, Plate Tectonic Unit, Black button on top…Google Earth Website, once there click the 5th link down: Plate Tectonic Boundaries. Then open with google earth. Name ______________________________ Hour______ 1. What type of boundary runs through California on the West coast of the USA? a. Transform b. Divergent c. Convergent 2. There is a divergent boundary on the northeast side of Africa. What is forming here because of that? a. Rift valley b. Trench c. Mid Ocean Ridge 3. What is this narrow sea’s name? ________________________ 4. Describe what will happen to the size of this body of water over the next 10 million years. __________________________________________________________________________________ 5. Find the plate boundary between the North American Plate and the African plate, which type is it? a. Transform b. Divergent c. Convergent 6. This is in an ocean, so what is forming here? a. Mid ocean ridge b. Trench c. Rift Valley 7. What happens to the age of the ocean rocks as you move away from the Mid Ocean Ridge? 8. Find India on your map. What type of collision is happening between India and Asia? a. Oceanic-oceanic b. Oceanic-Continental c. Continental-Continental 9. And what is being formed because of this boundary? ____________________________________ 10. Find Alaska. The Bering Sea is colliding with the Pacific Ocean plate . What boundary is this? a. MOR (mid ocean ridge) b. oceanic-oceanic c. oceanic-continental 11. The Aleutian Island are forming because of this…what do you call all these islands (blue notes) ________________________ 12. Attu is the last Aleutian island, this is an American Island. Use the Ruler, under the tools tab on top left. Click (don’t hold) on Attu and measure how many miles to the first island of Russia. ___________ 13. What type of collision is happening where the Nazca plate meets the South American plate? a. Oceanic-oceanic b. Oceanic-Continental c. Continental-Continental 14. What is the name of the trench that is forming at this boundary? _______________________________ 15. The smallest plate in the world is the Galapagos plate, West of the Galapagos Islands (it’s not labeled however). Find it and measure how many miles it is across. Measure from the north east corner to the south west corner. ______________ 16. How many microplates (small plates like the Galapagos) are in the Nazca plate? _____________ 17. Find Iceland…what two boundaries are found on that island? __________________, _________________ 18. Ms. Crownhart’s favorite plate is the Scotia plate, by South America. What is the name of the trench forming on the east side of that plate. (you have to zoom in) _________________________________ 19. The Marianas Trench is located by Guam. Which two plates are colliding here to form this trench? ______________________________, ______________________________ 20. Mount Saint Helens is part of the Cascade Range of volcanoes. Name two other volcanoes found nearby: a. b. 21. Why are these volcanoes forming on our continent?? (hint: look at the nearby boundaries, use your notes) ___________________________________________________________________________________________ 22. Go back to Mt. Saint Helens. Scroll in so you can see the volcanoes shape and slopes. Based on the topography what direction did this volcano erupt in March 18th 1980? __________________________________ 23. What Plate is the island of Madagascar part of? ______________________________ 24. How many miles long is Madagascar from top to bottom (use ruler)?___________________________ 25. Is the State of Hawaii near any plate boundary? _______________ a. Can you think of an explanation of why that volcano exists then??? ____________________________________________________________________________ 25. Which oceanic plate has the volcanoes forming on it: the Less dense or More dense plate? (hint: think about which plate is subducting and which is not) ______________________ 26. So therefore, which plate is less dense: the Caribbean Plate or the plates to its right? __________________________________________ Now find your house and see how cool that looks, or HMS or Ms. Crownhart’s house. (better not know this!)
