History of Pangea Alfred Weneger originated the theory of continental shift in 1915 He suggested continents plowed through ocean basins which would explain the puzzle fit of coastlines This theory was not accepted by scientists at first at the time they believed the Earth had its features because of heating and cooling Pangea originates from ancient greek and means “entire” http://vulcan.wr.usgs.gov/Glossary/PlateTectonics/des cription_plate_tectonics.html

History of Pangea (Cont.) Pangea existed in the Paleozoic and the Mezozoic eras Around the time of wenegers discovery other scientists believed the Earth had its features because of heating and cooling Alfred Wegener also earned his doctorate degree for astronomy, I think this helped him in how he understood how the Earth was madehttp://vulcan.wr.usgs.gov/Glossary/PlateTectoni cs/description_plate_tectonics.html

History of Pangea (cont.) Wegener credited Roberto Montavani and William Henry Pickering for their similar ideas Roberto had found similar formulations in the continents http://vulcan.wr.usgs.gov/Glossary/PlateTectonics/des cription_plate_tectonics.html

Convergent Boundary Convergent Boundary is an active deforming region where two or more tectonic plates moved and hit each other This formed mountains and volcanoes There is a boundary in South America where both the Nazca and South American faults are involved http://en.wikipedia.org/wiki/Convergent_boundary

Oceanic Continental Boundary http://en.wikipedia.o rg/wiki/Convergent_ boundary

Continental-Continental http://en.wikipedia.o rg/wiki/Convergent_ boundary

Oceanic-Oceanic convergence http://en.wikipedia.o rg/wiki/Convergent_ boundary

Divergent Boundaries A Divergent Boundary is a space between two tectonic plates that are moving away from each other Divergent Boundaries are related to Mountains Volcanoes and lava flow A known Divergent Boundary is the Alfaja Rift Valley Which involves the Eurasian and North American continental Tectonic Plates http://en.wikipedia.org/wiki/Divergent_boundary

Transform Boundaries A Transform Boundaries is a fault that runs along the boundary of a tectonic plate Transform Boundaries are related to causing earthquakes, Landslides, Trenches, and Mudslides A known Transform Boundary is the Alpine fault which runs along New Zealand’s coastline and is 500 miles longhttp://en.wikipedia.org/wiki/Transform_boundar y

Real World Connections We live on the North American Plate We are bordered by the African, Pacific, Filipino, Eurasian, and Caribean plates As of right now we and the U.S. are not in any immediate danger related to plate tectonics I believe the plates could all morph into one and create super earthquakes or create super volcanoes in the distant future http://en.wikipedia.org/wiki/Plate_tectonics H
