Ocean-continental convergence produces parallel belts of uplifted mountains and volcanic mountains mainly volcanic mountains parallel belts of folded mountains and volcanic mountains folded mountains only

mainly volcanic mountains

Explanation:

The convergent boundaries between the oceanic and continental tectonic plates are well known for their volcanic activity. On this boundaries, chains of volcanoes are forming, be it on land or in water. The reason for this is that the magma from the mantle layer manages to penetrate to the surface because the crust is under lot of stress, has lot of cracks, so the magma finds it easy to move up. As the magma reaches the surface, it starts to lift up the crust, and as it does, volcanic mountains are formed, which can vary in size, shape, and type. A nice example of this are the mountains along the Pacific Ring of Fire.

heat from the core of the earth causes convection currents to occur in the mantle. these currents slowly move the crust around.
