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
