Study Notes
Transform Fault Boundary
- Two tectonic plates slide horizontally past one another
- Also known as a conservative boundary as no crust is created or destroyed
- Driven by lateral shearing forces
- Generally vertical, running parallel to plate motion
- Little to no volcanic activity
- Known for earthquakes due to stress build-up along fault lines
Types of Transform Boundaries
- Oceanic Transform Faults:
- Associated with mid-ocean ridges
- Create fracture zones, linear features that mark the transition between offset segments of a mid-ocean ridge
- Continental Transform Faults:
- Found on land
- Create long fault lines, example: San Andreas Fault
Ridge-Ridge Transform Fault
- Breaks or offsets that occur along the intersection of two mid-ocean ridges
- Happen due to variations in the spreading rates of tectonic plates
- One side of a mid-ocean ridge spreading faster than the other can create a kink or offset where the two ridges meet
Ridge-Trench Transform Fault
- Connects a mid-ocean ridge (plates moving apart) to a subduction zone (one plate sliding beneath another)
- Acts as a transition zone between these two different types of plate boundaries
Triple Junction
- Where three tectonic plates meet
- At least one transform fault is present
