- Due to convection currents in the mantle, 2 continental plates are driven together.
- Over time the 2 plates will collide and be forced upwards forming a small fold mountain.
- After the mountain has been formed, the magma underneath the mountain starts to get hotter and burns the bottom of the mountain in order to find small cracks in the rock.
- When the magma reaches small cracks, the cracks start to enlarge.
- The magma starts errupting out of the top of the mountain and forms a volcano.
- When the magma has risen out of the mountain, it starts to sit on the top and cools, forming a new crust and developing the volcano to make it bigger.
