All about plate boundaries
The place where two or more plates meet is called a plate . If the two plates are moving apart, we call this a boundary because, as they separate, new emerges. A well-known island in the North Atlantic called Iceland was created in this way, part of a long chain of submarine mountains called a . When continental and oceanic crusts collide with one another, we call this a plate boundary. This can be two continental plates colliding or a continental plate colliding with an oceanic one. When a continental plate meets an oceanic plate, because the crust is denser, it sinks down towards the , where it melts, creating molten rock that will later re-emerge via a volcano. Where two continental plates collide, the crust is neither created nor but under pressure, creating mountains such as the which are between France and Italy.
