* Divergent boundaries: These are where plates move apart. As the plates pull away, magma rises from the mantle, creating new crust. This process often leads to earthquakes along the mid-ocean ridges and rift valleys.

* Convergent boundaries: These are where plates collide. The type of earthquake depends on the type of plates colliding:

* Oceanic-Continental: The denser oceanic plate subducts beneath the continental plate, leading to earthquakes along the subduction zone.

* Oceanic-Oceanic: One oceanic plate subducts beneath the other, also leading to earthquakes along the subduction zone.

* Continental-Continental: Both plates are equally dense, so they buckle and fold, creating mountain ranges and earthquakes.

* Transform boundaries: These are where plates slide past each other horizontally. The friction between the plates can cause earthquakes, as seen along the San Andreas Fault in California.

Therefore, earthquakes are not exclusively one type of plate boundary; they can occur at divergent, convergent, and transform boundaries.
