A volcano can be defined as a mountain that opens downward to a pool of molten rock deep beneath the surface of the Earth. When natural pressure created beneath the pool volcano erupts. During the eruption rock and gases shoots up through the opening of the volcano spill over the land and air with lava fragments. The dangerous area around the volcano can be considered under 20-mile radius. The volcanic ash is made up of pulverized rock that can be harsh, gritty and acidic in nature. These ashes can be harmful to the lungs of older persons and babies. The lightning we see during an eruption is caused by the friction between the ash and the surface, Let me tell you some of the important facts about Volcanoes,
