  1. WRITE WHAT IS IN GREEN Type of Plate Boundaries

  2. Divergent Plate Boundaries • Divergent Boundary: Between two lithospheric plates that are moving apart • DI-vergent/DI-vide • Rift Valleys: deep valleys at the center of a mid-ocean ridge • Sea-floor spreading: molten rock forces its way upward through cracks or rifts, forming new rock • Result in hydrothermal vents

  3. On page 5 of the ESRT, where are there Divergent Boundaries?Draw it out with Geology.Com!

  4. Convergent Plate Boundaries • Convergent Boundary: Between two plates that are moving toward each other • CO-nvergent/CO-me together • Subduction boundary: An area where an oceanic plate goes beneath another plate • Results in volcanoes

  5. On page 5 of your ESRT, where are the CONVERGENT boundaries?Draw it out again with Geology.com

  6. Collision Plate Boundary • Collision Boundary: Type of convergent boundary in which 2 continents may become 1 continent • Example: Himalayas->result of India pushing into China at a rate of 5cm per year

  7. Transform Boundary • Transform Boundary: Located between 2 plates that are sliding past each other. • According to page 5 of the ESRT, where is there a transform boundary? • Guess what?? Draw it out!

  8. Causes of Plate Movement • Mantle convection: The process in which heat from Earth’s inner and outer cores is transferred through the mantle • Ridge push: A force exerted by cooling, subsiding rock on the spreading lithospheric plates at the mid-ocean ridge • Slab pull: A force at a subduction boundary that the sinking edge of the sinking plate exerts on the rest of the plate

  10. Visualization • Seeing is believing • In case you need another look
