Convergent Boundaries: These occur when two tectonic plates collide. Three types exist: continental-continental collisions (forming mountains), continental-oceanic collisions (resulting in volcanoes), and oceanic-oceanic collisions (creating island arcs).
Divergent Boundaries: Here, plates move apart, allowing the asthenosphere to rise and melt, forming new crust (oceanic or continental) at mid-ocean ridges or rift valleys. Transform Boundaries: Characterized by horizontal plate movement, these boundaries cause earthquakes due to the friction between plates. Unlike convergent and divergent boundaries, they generally do not produce magma; the San Andreas Fault serves as a prime example.
