Aside from serious disasters posed to humans and property, active volcanoes also produce serious environmental effects. The commonly-known threat a volcano can present is the flow of super-heated rock known as lava. This lava causes fires and will destroy everything in its path. In addition, a tsunami can develop and damage shorelines. Furthermore, active volcanoes have an intense impact on the stratosphere, the second layer of the atmosphere. Gases released from the eruption convert sulfur dioxide to sulfuric acid, which condenses in the stratosphere. This greenhouse gas traps heat in the atmosphere.
