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

 Alfred Wegener  Alfred Wegener originated the theory of Pangaea  Being a German Scientist geophysicist, and meteorologists all helped him with his discovery.

 He originated the theory in autumn of  In the Library at his University astronomy/planets/earth/Continents.shtml

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

 No it was not accepted because the actual forces generated by the rotation of the earth were calculated to be insufficient to move continents. my/planets/earth/Continents.shtml

 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.

 A major geologic suture marking the juncture of lithospheric plates that were joined by plate tectonics.  Earthquakes  Earthquakes and volcanoes can form  ics/description_plate_tectonics.html

 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.  ctonics/description_plate_tectonics.html

 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 /description_plate_tectonics.html

 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. /description_plate_tectonics.html

 We were on the North American Plate 

 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 

 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.  survey/html/geo_f03/tabid/830 7/Default.aspx

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

 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 

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