* Divergent boundaries: Where plates move apart from each other. This is where new crust is formed. You can find divergent boundaries at mid-ocean ridges and rift valleys.
* Convergent boundaries: Where plates move towards each other. This is where crust is destroyed. You can find convergent boundaries at subduction zones (one plate dives under another) and collision zones (two continental plates collide).
* Transform boundaries: Where plates slide horizontally past each other. This is where crust is neither created nor destroyed. You can find transform boundaries at areas like the San Andreas Fault in California.
So, to find two tectonic plates, you'd look for any of these plate boundaries!
