Plate Boundaries are at the edges of Plate Tectonics. There are 3 types of Plate Boundaries: Transform, Divergent, and Convergent Boundaries. These boundaries are there for the different type o plate tectonics and crust.
CONVERGENT BOUNDARY OO:
There are two plates. The two plates come together. Subduction occurs between them. What I mean by subduction is that the most dense one will go under the less dense one. This forms a trench.

LESS DENSEPLATE
CONVERGENT BOUNDARY CC:
The two plates come together. When they converge, neither is subjected and both plates buckle and move upwards. This forms either a mountain or volcanoes. Earthquakes can occur at convergent plate boundaries.
CONVERGENT BOUNDARY OC:
The same thing happens as a convergent boundary with oceanic and oceanic. You can find volcanic arcs near the subduction zone. You can also find continental volcanoes.
MOST DENSE PLATE
LESS DENSE PLATE
TRANSFORM BOUNDARY:
The 2 plates slide past each other. The crust is neither created or destroyed. Earthquakes will occur more when the plates slide past one another.
