The mountain is one of the natural resources (read: renewable and non-renewable natural resources) in the world. The mountain is one of the bulge that is on the surface of the earth. Inside the mountain bulge there is a vertical straight channel like a natural pipe. This pipe connects between the earth's bowels with the Earth's surface or the earth's crust. The stomach of the earth contains a variety of hot liquids, such as liquid bataun and magma. At one time magma and material in the bowels of the earth will experience saturation. Or caused by the vibration of the earth (tectonic earthquake), magma in the bowels of this earth will come out to the surface of the earth (read: the shape of the earth's surface) on a regular basis. The magma goes out to the surface of the earth through a natural pipe towering in the mountains. When the magma comes out through the natural pipe, then this is called the mountain erupts. So as if the volcano erupted a variety of material from the earth.
