Plate TectonicsPlate Tectonics
• The theory that pieces of Earth’s lithosphere are in constant motion, driven by convection currents in the mantle.
• CD + SFS + “plates” = Plate Tectonics!

FaultsFaults
• Breaks in earth’s crust where rocks move

Faults meet at BoundariesFaults meet at Boundaries
• 3 kinds of boundaries:
• Convergent
• Divergent
• Transform

Divergent BoundaryDivergent Boundary
• Where 2 plates move apart
• Mid-ocean ridge (oceanic)
• Rift Valley (continental)

Convergent BoundaryConvergent Boundary
• Where 2 plates collide
• Oceanic-Oceanic
• Oceanic-Continental
• Continental-Continental
• Outcome determined by DENSITY
