The type of plate boundary that creates continental mountains is a continent- continent convergent boundary. When two continental plates collide, they push against each other and the crust is forced upwards, forming large mountain ranges like the Himalayas. This collision causes the crust to thicken and buckle, producing mountains rather than subduction because continental crust is too buoyant to sink into the mantle. These are also known as collision boundaries. This process does not typically involve volcanism, as the thick continental crust prevents magma from reaching the surface. Some of the world's tallest and most famous mountain ranges, including the Himalayas and the Appalachian Mountains, were formed by this type of boundary.
