Volcanic mountains are formed when molten lava, ash, cinder and dust from deep inside the earth come out on the surface through cracks in the earth’s crust and accumulate in the shape of high cones. The opening through which lava and other materials come to the surface is called a vent. The funnel-shaped depression at the top of a vent is called a crater.
Examples – Mountain Fujiyama in Japan, Mountain Mayon in the Philippines.
