  1. Plate Tectonics Plate Boundaries and Motion

  2. Plate Boundaries • Divergent Boundary – moving _____ • Convergent Boundary – moving ________ • Transform Fault Boundary – moving ________________________ apart together sideways past each other

  3. Divergent boundary of two continental plates. Creates a __________. Example: _____________ East African Rift rift valley

  4. Divergent boundary Divergent boundary

  5. Convergent boundary of two oceanic plates. Creates an ________ and a _____. Example: _____ island arc trench Japan

  6. Convergent boundary Convergent boundary Subduction

  7. Convergent boundary of an oceanic plate and a continental plate. Forms a _______ mountain range and a ______. Examples: _______ or _______ Mts volcanic trench Andes Cascades

  8. Convergent boundary of two continental plates. Forms a ______ mountain range. Examples: ___________, Alps, ______________ folded Himalayas Appalachians

  9. Transform-fault boundary where the North American and Pacific plates are moving ____ each other. Example: ________________ in California past San Andreas Fault

  10. Transform boundary Transform boundary

  11. Plate Boundary Summary Type of Boundary Process Involved Characteristic features Examples

  12. Plate Boundaries Review • Places where plates move apart are called _____________ boundaries. • When continental plates diverge a ___________ is formed. • When two oceanic plates converge what is created? _________________ • The Appalachians formed mainly from continental plate collisions and therefore are a __________ mountain range. • The force moving the plates is ____________ . divergent rift valley an island arc and a trench folded Convection currents
