Plate Tectonics Web quest Name: __________________________________ Period: __________ Date: _____________ Observe animations of processes that occur along plate boundaries http://www.classzone.com/books/earth_science/terc/content/visualizations/es0804/es0804page01.cfm?chapter_no=visualization What occurs at each of the three main types of plate boundaries: transform, convergent, and divergent boundaries. You should write a short piece in which you compare and contrast the three types of boundaries. Observe an animation showing growth of a continent http://www.classzone.com/books/earth_science/terc/content/visualizations/es0808/es0808page01. cfm?chapter_no=visualization What does it take for a continent to grow? Make a prediction before you begin and compare your results. Each of the next three animations depicts one of the distinct ways that volcanoes form. The three together provide a nice body of evidence for plate tectonics and reinforce the theory's explanations about where and why geological events occur. Observe an animation of volcanism at a subduction zone http://www.classzone.com/books/earth_science/terc/content/visualizations/es0902/es0902page01.cfm?chapter_no=visualization What type of boundary is this? How do you know? Why does the oceanic plate subduct under the continental plate and not the other way around. Observe an animation of volcanism along a rift zone http://www.classzone.com/books/earth_science/terc/content/visualizations/es0903/es0903page01. cfm?chapter_no=visualization In terms of volume, more volcanic rock is produced in the oceans than on land. This animation reveals what occurs at divergent plate boundaries, most of which are on the seafloor. What kind of information does this give you about the age of rock in comparison to a rift zone? Observe an animation of volcanic islands forming over a hot spot http://www.classzone.com/books/earth_science/terc/content/visualizations/es0904/es0904page01.cfm?chapter_no=visualization The movie control buttons really come in handy here. How does this animation provide evidence of plate tectonics? How do scientists determine the age of islands? The island chain illustrates the continuous nature of plate movement throughout Earth's history.
