DISCOVER OUR EARTH http://www.geo.cornell.edu/hawaii/220/PRI/PRI_PT_contdrift.html Click on the link to answer the following questions Continental Drift 1. List one types of supporting evidence that Alfred Wegener noted as theories to there being one giant supercontinent. 2. Try to reconstruct pangea….DO Not Skip This Part! TRY IT!!!!!!!! Earthquakes Click on Earthquakes to the left 3. Draw the earthquake basics: label the following ( fault, focus, epicenter) 4. In what 3 directions can both earthquakes and tectonic plates move? PT Basics (Plate Tectonics) Click on PT Basics to the left 5. The surface of the Earth is always in motion, driven by _______________________. 1 Plate Boundaries Click on Plate boundaries to the left 6. If I wanted to determine where 2 plates meet, what are 3 different surface features of earth that would indicate to plates are colliding? a. ____________________ b. __________________ c. ________________________ 7. Click on the what do you think tab: List 2 facts about plate boundaries. 8. Click on divergent plate boundaries: List 2facts about divergent plates 9. With arrows, indicate which way divergent plates will move 10. Click on Convergent plates to the left hand side of the screen: What are convergent plate boundaries? 11. With arrows, indicate which way divergent plates will move 2 12. Click on the ocean-to-ocean = subduction link: What 3 things can occur where ocean-to-ocean subduction occurs? _________________________ _________________________ ___________________ 13. How do volcanoes form? 14. Click on the continent-to-continent = subduction link: What formation is the result of two plates colliding? 15. Click on Transform bundarys to the left hand side of the screen: With arrows draw the directions of a transform plate boundary 16. Here ______________________is neither created nor destroyed. 17. California’s _____________________________fault is an example of transform boundary Plate Motion 18. Click on plate motion to the left: Watch the video on convection currents and read the description of convection currents. Diagram convection currents in the box, include arrows and the direction of cool and hot mantle. 3 Mountains Click on Mountains to the left. 19. In what 2 ways are mountains compared to icebergs? Try to see what happens when you change the thickness of Earth’s crust Volcanoes Click on Volcanoes to the left: Read the information about volcanoes Click on the “what do you think” link. 20. What determines a volcanoes eruption style? 21. What type of boundary brings about violent volcanoes? 22. Why? Hotspot 23. 4 Click on Hotspots to the left: What is a hotspot?
