An explosion creates a shock wave. Types of explosives Natural Explosions do not commonly occur in nature. Below Earth, most natural explosions arise from volcanic processes of various sorts. Explosive volcanic eruptions occur when magma rising from below has much dissolved gas in it; the reduction of pressure as the magma rises causes the gas to bubble out of solution, resulting in a rapid increase in volume. Explosions also occur as a result of impact events. On other planets, volcanoes and impacts cause explosions with various frequency. Chemical The most common artificial explosives are chemical explosives, usually involving a rapid an
