Plate Tectonics

Earth's Crust made up different sections "plates" that move dynamically (collide, extend, slide)

Earth's Lithospheric (Crustal) Plates

Plate Tectonics

• Divergent

  • Constructive margin

  • Moving apart and expanding

  • Lithosphere thickens away from the axis

• Convergent

  • Destructive margins

  • Moves into each other

  • Process of consuming a plate is called subduction

• Transform

  • Conservative margins

  • Moves parallel

  • No new plate forms, and no old plate is consumed

Alfred Wegener

• Proposed hypothesis of Continental Drift
