Flashcards

Normal Fault

Rock moves down due to the tension from divergent boundaries.

Reverse Fault

Rock moves upward due to squeezing and compressional forces from convergent boundaries.

Strike-Slip Fault

Rocks slide past each other in opposite directions, typically caused by transform boundaries.

Divergent boundary

Boundary where tectonic plates move away from each other.

Study Notes

  • Normal faults occur when rock moves down.
    • These are associated with divergent boundaries.
  • Reverse faults occur when rock moves upward.
    • These are associated with convergent boundaries.
  • Strike-slip faults occur when rocks slide past one another in opposite directions.
    • These are associated with transform boundaries.
