Geography: Plate Tectonics

• California borders the Pacific plate and the North American Plate.
• A Divergent boundary creates new ocean floor.
• A Convergent boundary creates mountains.
• Transform


  In this boundary plates slide past each other.
• Convergent


  In this boundary the plates come togehter.
• Divergent


  In this boundary the plates move away from each other.
• Great African Rift


  This place is in Africa and the plates are coming apart.
• Midocean ridge


  an underwater chain of mountains.
• Convergent


  this type of ocean to ocean boundary would create a trench.
• Japan


  This country is an example of island arc.
• Sea Floor Spreading creates midocean ridges, earthquakes, and volcanic activity.
• Mid Atlantic Ridge


  This is an example of a mid ocean ridge.
• East Pacific Rise


  This is an example of sea floor spreading at a divergent boundary.
• At a convergent convergent boundary where an ocean meets a continent, the ocean dives under. This is called Subduction
• Volcanoes and Earthquakes are features found at an ocean to continent convergent boundary.
• Western Coast of South America

  This is an example of a subduction zone at a convergent boundary between a continent and an ocean.
• True


  T or F, a subduction zones would have earthquakre activity.
• False


  T or F, a subduction zone occurs where to plates move away from each other.
• False


  T or F California is an example of an island arc.
• True


  T or F Indonesian Islands are an example of an Island arc.
• False


  T or F A divergent boundary would create mountains.
• False


  T or F there are only two types of convergent boundaries.
• True


  T or F Japan is an example of an island arc.
• True


  T or F You will find earthquake activity in a continent to continent convergent boundary.
• False


  A transform boundary creates mountains.
• Continental drift: Theory proposed by Alfred Wegener suggesting continents were once joined together as one supercontinent Pangaea
• Seismic waves: Waves produced when an earthquake occurs
