INTERNAL FORCES THAT SHAPE THE EARTH Chp. 2 Section 3
Learning goal: • Explain plate tectonics and the effects they have on our planet
Continental Drift Theory • All continents had once been joined together in a supercontinent called Pangaea, but slowly drifted apart. • Evidence: the same crocodile fossils were found in Brazil and South Africa • Evidence: continents can fit together like puzzle pieces
Plate Tectonics • Tectonic plates=big moving pieces of the earth’s lithosphere • Continents split apart due to the movements of tectonic plates
4 Types of Plate Movement
http: //earthquake. usgs. gov/learn/animations/animation. php? flash_title=Divergent+Boundary&flash_file=divergent&flas h_width=500&flash_height=200 1. Diverging Plates spread apart *The space between is filled with magma, which forms underwater mountain ranges
An effect of divergent plate movement is a…VOLCANO! Ring of Fire: zone around the Pacific plate known for multiple volcanic eruptions/earthquakes
2. Convergent : Subduction One plate moving under another * “sub”=under, like submarine http: //earthguide. ucsd. edu/eoc/teachers/t_te ctonics/p_subduction. html
3. Convergent: Collision Plates come together * “con”=to come together like “con”vention *When the plates collide, they create large mountain ranges like the Himalayas.
World’s tallest: Mount Everest
4) Transformation Plates slide past one another • When plates slide past one another at a fault, like the San Andreas, it can cause an earthquake • Fault= crack/joint in the earth
Earthquakes • Caused when tectonic plates grind or slip • Richter Scale: scale that rates earthquakes (1=10) Haiti— 7. 0
Tsunamis • BBC NEWS | World | The tsunami disaster explained A giant wave caused by an earthquake on the ocean floor. Indian Ocean— 9. 1
Create a newspaper article! • Pick an event: earthquake, volcano eruption, tsunami…Can be more than one! (i. e. earthquake & tsunami) • Explain exactly what happened. Be specific! Tell where this happened, tell what type of plate movement it was and explain how those plates move, explain the damage of the disaster. • Draw a picture to explain how this happened (plate movement arrows) and a picture of the damage it caused.
Article Title Author Draw a picture to explain how this happened (illustrate the plate movements) Draw a picture of the damage it caused Keep it appropriate… Caption explaining the above picture Date • Pick an event: earthquake, volcano eruption, tsunami…Can be more than one! (i. e. earthquake & tsunami) • Explain exactly what happened. Be specific! Tell where this happened, tell what type of plate movement it was and explain how those plates moved, explain the damage of the disaster. • At least 10 sentences, be creative but still cover the content!
