Plate tectonics

PLATE TECTONICS

Causes of plate tectonics
Causes of Plate Tectonics

  • Mantle Convection

    • Transfer of thermal energy by the movement of heated matter in the mantle

      • Rising mantle – divergent boundary

      • Falling mantle- convergent boundary

  • Push and Pull

    • Ridge push

    • Slab pull


Types of boundaries
Types of Boundaries

  • CONVERGENT

    • Where 2 tectonic plates are moving together

      • Creates a subduction zone

    • Trenches, island arcs and folded mountains

  • DIVERGENT

    • Where 2 tectonic plates are moving apart

    • Volcanism, earthquakes and high heat flow

  • TRANSFORM

    • Where 2 tectonic plates are sliding horizontally past one another

    • Long faults and shallow earthquakes


Convergent destroy
Convergent = Destroy

oceanic-continental

continental-continental

oceanic-oceanic

  • Form either a subduction zone or a continental collision

  • Earthquakes and volcanoes are common

  • Oceanic-Continental

    • Cascade Mountain Range

  • Continental-Continental

    • Himalayas

  • Oceanic-Oceanic

    • Mariana Trench, Japan, Aleutian Islands



Divergent create
Divergent = Create

  • Black Hills, SD

  • East African Rift Valley

  • Red Sea

  • Mid-Atlantic Ridge


Transform conserve
Transform = Conserve

  • Two Types

    • Dextral – right side to observer

      • San Andreas Fault

    • Sinistral – left side to observer
