Here's a breakdown of what happens at convergent boundaries:
* Oceanic-Continental Convergence: When an oceanic plate collides with a continental plate, the denser oceanic plate subducts (slides) beneath the continental plate. This process creates:
* Volcanoes: As the oceanic plate sinks, it melts, and the magma rises to the surface, forming volcanoes along the continental margin.
* Deep-sea trenches: The point where the plates meet forms a deep trench in the ocean floor.
* Earthquakes: The movement of the plates causes earthquakes along the subduction zone.
* Oceanic-Oceanic Convergence: When two oceanic plates collide, the denser plate subducts beneath the other. This results in:
* Island arcs: As the subducting plate melts, volcanic islands form along the convergent boundary.
* Trenches: A deep trench forms where the plates meet.
* Earthquakes: Earthquakes occur along the subduction zone.
* Continental-Continental Convergence: When two continental plates collide, neither plate subducts because they have similar densities. This creates:
* Mountain ranges: The plates buckle and fold, creating massive mountain ranges.
* Earthquakes: Earthquakes occur along the collision zone.
Let me know if you'd like more details about any of these types of convergent boundaries!
