* Divergent Boundaries: These are areas where plates are moving apart. Magma rises from the mantle to fill the gap, creating new crust and often leading to undersea volcanic activity.
* Convergent Boundaries (Subduction Zones): Here, one plate slides beneath another. As the subducting plate melts, it creates magma that rises to the surface, resulting in volcanic arcs.
* Transform Boundaries: These are areas where plates slide past each other horizontally. While not as common, some volcanic activity can occur due to the friction and pressure generated at these boundaries.
In summary: The vast majority of active volcanoes are found along these three types of plate boundaries, reflecting the dynamic processes that shape our planet.
