A convergent plate boundary is an area where two plates collide! (a way we were taught to remember it is that convergent and collide both start with a c)
A convergent boundary is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other causing a process known as subduction. The subduction zone can be defined by a plane where many earthquakes occur, called the Wadati–Benioff zone.
