1 By: Madelyn Kappers Plate Plate~ a large section of the lithosphere that reacts to tectonic forces as a unit and moves as such.

2  Alfred Wegener  Alfred Wegener originated the theory of Pangaea  Being a German Scientist geophysicist, and meteorologists all helped him with his discovery. http://www.ucmp.berkeley.edu/geology/techist.html

3  He originated the theory in autumn of 1915.  In the Library at his University http://www.enchantedlearning.com/subjects/ astronomy/planets/earth/Continents.shtml

4  The Pangaea theory~ that states were all once together as one known as a 'supercontinent' called a Pangaea.  http://scign.jpl.nasa.  gov/learn/plate2.htm

5  No it was not accepted because the actual forces generated by the rotation of the earth were calculated to be insufficient to move continents. http://www.enchantedlearning.com/subjects/astrono my/planets/earth/Continents.shtml

6  Arthur Holmes and Harry Hess both assisted on the recognition of Wegner`s theory. They related by based on mantle convection currents, now known as "sea floor spreading". the idea that the mantle undergoes thermal convection. http://www.ucmp.berkeley.edu/geology/techist.html

7  A major geologic suture marking the juncture of lithospheric plates that were joined by plate tectonics.  Earthquakes  Earthquakes and volcanoes can form  http://vulcan.wr.usgs.gov/Glossary/PlateTecton ics/description_plate_tectonics.html

8  An example of a continental- oceanic subduction zone is the area along the western coast of South America where the oceanic Nazca Plate is being subducted beneath the continental South American Plate.  http://vulcan.wr.usgs.gov/Glossary/PlateTe ctonics/description_plate_tectonics.html

9  Divergent Boundaries are locations where plates are moving away from each other. Volcanoes  It would happen to Volcanoes mostly. Mountains~  This mostly forms volcanic islands. And Mountains~ natural elevations of the earth's surface rising more or less abruptly to a summit, and attaining an altitude greater than that of a hill http://vulcan.wr.usgs.gov/Glossary/PlateTectonics /description_plate_tectonics.html

10  Transform Boundary  Transform Boundary~ location where two plates slide past each other.  Example is that the Pacific pate and the North American Plate side by each other.  They create large earthquakes and Fault lines. http://vulcan.wr.usgs.gov/Glossary/PlateTectonics /description_plate_tectonics.html

11  We were on the North American Plate  http://geology.com/plate-tectonics.shtml

12  The Caribbean Plate, the Juan De Fuca Plate, the Cocos Plate, the Pacific Plate, the Eurasian Plate, the African Plate, the South American Plate, and the Nazca Plate.  Boundary~  Boundary~ something that indicates bounds or limits  http://geology.com/plate-tectonics.shtml

13  Google images

14  I don’t think that we are in any danger because there has been over 200 Earthquakes since 1776 and not a lot of them were bad. The Past 15 that we have had only injured a couple of people.  http://www.dnr.state.oh.us/geo survey/html/geo_f03/tabid/830 7/Default.aspx

15  Maybe all of the plates would form as one and create a HUGE Earthquake the can destroy all of man kind.

16  Trench~  Trench~ a deep furrow, ditch, or cut.  Landslide~  Landslide~ Downward falling or sliding of a mass of soil, detritus, or rock on or from a steep slope.  Mudslide~  Mudslide~ the rapid downward movement of a large quantity of saturated earth  WWW.DICTIONARY.COM

17 Volcano!!! Volcano!!! Map of the USA!!! Aftermath of an earthquake!!!!!!! Mountain!!

18 After a landslide After a Mudslide Trench in the Ocean
