NAME:____________________________PER._____________________ Plate Tectonics and Earthquake Scavenger Hunt 1st SITE: Puzzles of the Earth http://library.thinkquest.org/17701/high/index.html Go to Earth Structures to start your tour of the world of plate tectonics! Click the puzzle piece at the bottom of each page to navigate your way through the world of plate tectonics. 1. What are the three main parts of the earth? Give a brief description for each. 1.__________________________________________ 2.__________________________________________ 3.__________________________________________ 2. The plates that make up the crust fit together like pieces of a _______________. 3. Which plate do we live on? ___________ _____________ (Hint: Earth Map) 4. We live on the earth’s outermost layer. What is it called? ________________ 5. Match each description using a C for continental plates or O for oceanic plates. _____ Crust that "carries" the ocean _____ Crust that "carries" the continents; may also contain oceans _____ Less dense and tends not to subduct _____ More dense and tends to be subducted 6. How do plates move? Write a description using the terms magma, plates, and convection currents. 7. What happens at a convergent boundary? Explain and draw a diagram! 8. What happens in each situation? Continental plate meets oceanic plate Two continental plates meet Two oceanic plates meet - 9. What happens at a divergent boundary? Explain and draw a diagram! 10. What is sea-floor spreading? 11. Describe transform plate movement. Explain and draw a diagram! 12. What are three geographic features that may be found at plate boundaries? 2nd SITE: ZOOM Plate Tectonics 1. How fast are the plates moving? ____ to ____ cm per year 2. Who first proposed the idea of continental drift? _______________ ________________ 3. What did he name the gigantic supercontinent that existed 200 million years ago? ____________ 4. When did it begin to break up? _________________ Period 5. What were the names of the two smaller supercontinents created by the break up? _____________________ and ________________ 6. Click and watch them drift 3rd Site Click on the questions to link to the site with answers and explanations What are earthquake (Seismic) Waves? Fill in the blanks ________________waves, which are similar to sound waves, and ___________________waves, which are a kind of shear wave. Within the earth, ______________waves can travel through solids and liquids, whereas ________________ waves can only travel through solids. Become a virtual seismologist go to this link complete the activity and e-mail certificate of completion You must complete this activity and receive a personalized Certificate as a "Virtual Seismologist”. This is worth 10points E-mail certificate to your instructor [email protected] classcode is 1723370 Think About It! Take a few moments to reflect on your journey through the world of plate tectonics and Earthquakes! What topic(s) would you like to explore further? Examples: Earthquakes, Volcanoes, Lava tubes, Islands, etc. 4th Site http://www.iris.edu/seismon/ Earthquakes now Name 5 places where earthquakes are occurring today. What magnitude are they (Drag your mouse over the red circles to find place and magnitude) 1. 2. 3. 4. 5. 5th SITE: Virtual Earthquake Fill in the blank with the correct term from the caption below the photo of each Earthquake Alaska 1964 1.) The massive earthquake centered near Valdez had a Richter magnitude of ____________. The 1964 Alaska earthquake remains the strongest on record in North America. Northridge, CA 1994 2.) Freeway overpasses are not able to withstand____________ forces generated during the earthquake. San Francisco 1906 3.) A large historic earthquake and subsequent______________ decimates the city. San Francisco (Loma Prieta earthquake) 1989 4.) San Francisco (Loma Prieta earthquake) 1989: Fire erupts in the hard-hit "Marina District" of the city. A sizeable portion of the Marina District is built upon ______________________ material. Some houses built on such material suffered considerable structural damage. Turkey 1997 5.) Large earthquake on the Anatolian Fault causes substantial damage to _______________ masonry buildings in northern Turkey. Quiz Try the Plate Tectonics Quiz listed on the Earth Science page!
