 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”

 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

 Wegener credited Roberto Montavani and William
Henry Pickering for their similar ideas Roberto had
found similar formulations in the continents

 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

 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

 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

 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
