Here's a breakdown of what happens:
* The denser plate (usually an oceanic plate) dives beneath the less dense plate (usually a continental plate). This is because oceanic crust is thinner and made of denser rock than continental crust.
* As the denser plate sinks, it melts partially due to the heat and pressure.
* This molten rock rises towards the surface, often triggering volcanoes and forming mountain ranges along the convergence zone.
* The process also leads to earthquakes as the plates grind against each other.
This process is responsible for some of the most dramatic features on Earth, including the Andes Mountains, the Cascade Range, and the Japan Trench.
