Final answer:
When continental plates collide at a convergent boundary, they create mountains through a violent process with earthquakes and rock deformation.
Explanation:
Continental plates are thicker and more buoyant than oceanic plates. When they collide at a convergent boundary, if it involves two continental plates, they cannot subduct due to their low density. Instead, they collide and form mountains through a violent process that includes earthquakes, rock deformation, and uplift of mountains.
