  1. PLATE TECTONICS BY: Andrew Fiora

  2. PANGAEA section 1 • A man named Alfred Wegener made the theory in 1912 that once all the continents were together and he called it Pangaea. • It was over an estimated 300 million years ago when all of the continents were together. • Pangaea occurred in the Paleozoic era • The theory that all the continents were once all of the continents were together was originally not believed by scientists because the actual forces generated by the rotation of the earth were calculated to be insufficient to move continents. • Alfred was an astronomer and a meteorologist this helped him when he originate the idea of Pangaea

  4. Convergent boundaries section 2 • The definition of a convergent boundary is where an area on the Earth's surface where two tectonic plates come together. • The Himalaya Mountain Range is the best active examples of this type of plate boundary. • The definition of a mountain is A large landform that is higher Than the land surrounding it

  5. The definition of a mountain is A large landform that is higher Than the land surrounding it • The Himalayan mountains mountainas

  6. Divergent Boundary section 3 • The definition of a Divergent Boundary is a plate boundary where new crust is being created as the old crust on each side moves away as if on a conveyor belt • Examples of a divergent boundaries are earthquakes and volcanoes • A earthquake is shaking and vibration at the surface of the earth resulting from underground movement • The definition of a volcano is A volcano is an opening, in the surface which allows hot magma to escape

  8. Transform Boundaries section 4 • The definition of a transform boundary is a fault or transform boundary, also known as conservative plate boundary, is a fault which runs along the boundary of a tectonic plate. • Most transform faults are found in the ocean basin and connect offsets in the mid-ocean ridges • Some major example is the san Andréas fault in California and the north antolian fault in Turkey • A plate is a underground layer that moves and causes earthquakes

  10. Real world connections section 5 • We are on the north American plate • The plates that boarder the united states are the united states and the pacific plate • Most of the earthquake that occurs are all the way out near California so we do not really have to worry about any earthquakes • In the future I think the united states will see more earthquakes, tornadoes, volcanic eruptions, landslides and mudslides • is a scientific theory which describes the large scale motions of Earth's lithospher • We do not really have to worry because we are really not near any earthquake zones

  11. Landslides and mudslides • A mudslide is a landslide of mud • A landslide is disaster that involves the breakup and downhill flow of rock, mud and water
