Answer: Divergent boundaries -- where new crust is generated as the plates pull away from each other. Convergent boundaries -- where crust is destroyed as one plate dives under another. Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other.
Explanation: There are three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries. ... A divergent boundary occurs when two tectonic plates move away from each other.
