What are the 4 types of boundaries for tectonic plates?

The four types of tectonic plate boundaries are divergent, convergent, transform, and boundary zones. Divergent boundaries occur where plates move apart, leading to the formation of new crust, often seen at mid-ocean ridges. Convergent boundaries form when plates collide, resulting in subduction or mountain building. Transform boundaries occur where plates slide past each other horizontally, which can cause earthquakes.
