Name:_________________________________________ Period: 1 2 3 4 5 Date:________________ Plate Tectonics Webquest Go to webquest links on the class website to find links: www.murrayphysics.wikispaces.com Go to: http://www.ucmp.berkeley.edu/geology/tecmech.html The four main features of plate tectonics are: • • • • Go to the following link and answer the questions: http://www.enchantedlearning.com/subjects/astronomy/planets/earth/Continents.shtml How long ago did the Earths crust solidify?_______________________ Is the crust a solid shell? No Yes Why or why not? What are the plates made of?_____________________ How thick are the plates?____________________________ What factors cause the map of the Earth to change? What does “plate tectonics” mean? ________________ ___________________ When was the theory developed?__________________ What does it explain? What other phenomena does it explain? How fast are the plates moving? _____________________ Where does most of the Earth’s seismic activity occur? What is seismic activity? Give one fact about the crust: What is the rocky mantle made of? What is the upper mantle called?___________________________ What is the lower mantle called?____________________________ What is seafloor spreading? What forms where the seafloor is spreading? Who discovered seafloor spreading? _________________ and ____________ When? _________ What did Alfred Wegner propose in 1915? What did he hypothesize? What does Pangaea mean? _______-_____________________ When did Pangaea exist? ____________________________ What is a Mesosaurus? What is a Glossopteris? What do they have to do with plate tectonics? Go to the following link on seafloor spreading: http://earthguide.ucsd.edu/eoc/teachers/t_tectonics/p_seafloorspreading.html Where does seafloor spreading take place?______________ What does it produce?__________________________ Give 2 examples of midocean ridges: How high is a typical midocean ridge “mountain”? What is the other major process of plate tectonics? Explain how new material forms at places where seafloor spreading is occurring: What characteristics of the seafloor does seafloor spreading produce ! 1. ! 2. ! 3. ! 4. Go to the following link: http://library.thinkquest.org/17457/platetectonics/5.php What is subduction? Which plate slides under the other plate when subduction is happening? What is faulting? What causes earthquakes (yet again!!!)? What do you call the area where subduction occurs? What causes the subducted plate to melt? ! 1. ! 2. ! 3. What does it produce? What forms when large areas of crust are melted? Go to the following link: http://www.sanandreasfault.org/Information.html What is the name of the most famous fault in the world? What event partly caused its notoriety? Which two plates come together at the San Andreas Fault (you have to read down a bit)? How long is the San Andreas Fault? _____________ miles How deep is it? ___________________ miles What is elastic rebound? What does it cause? How old is the San Andreas Fault? What is the slip rate along it? EXIT TICKET MUST BE DONE!!!!!!!!!! Go to the following website http://www.classroomclipboard.com/509540 Give access code: UCDTN24 and your name and answer the questions. Make sure you choose the finish test button at the end. You will see your grade!!! This will be graded by the computer and the grades will be sent to Ms. Murray automatically!!!!! Make sure you see your test score or you aren’t done!!!!
