Plate Tectonics

Where new crust is generated as the plates pull away from each other.

• Convergent boundaries

• Transform boundaries

• Plate boundary zones

• Divergent boundaries

where crust is destroyed as one plate subducts (dives) under another.

• Transform boundaries

• Convergent boundaries

• Divergent boundaries

• Plate boundary zones

where crust is neither produced nor destroyed as the plates slide horizontally past each other.
