Editing Smog (section)

====Volcanoes====
An erupting volcano can emit high levels of [[sulfur dioxide]] along with a large quantity of particulate matter; two key components to the creation of smog. However, the smog created as a result of a volcanic eruption is often known as [[vog]] to distinguish it as a natural occurrence. The chemical reactions that form smog following a volcanic eruption are different than the reactions that form photochemical smog. The term smog encompasses the effect when a large number of gas-phase molecules and particulate matter are emitted to the atmosphere, creating a visible [[haze]]. The event causing a large number of emissions can vary but still result in the formation of smog.
