Editing Vog (section)

==Description==
Vog is created when [[volcanic gas]]es (primarily oxides of [[sulfur]]) react with sunlight, [[oxygen]] and [[moisture]]. The result includes [[sulfuric acid]] and other sulfates.<ref>[http://www.epa.gov/air/urbanair/so2/index.html "Sulfur Dioxide"] on US Environmental Protection Agency web site</ref> Vog is made up of a mixture of gases and aerosols which makes it hard to study and potentially more dangerous than either on their own.<ref name=usgs/>

Vog, which originates from volcanic vents, differs from [[Laze (geology)|laze]], created when lava enters the ocean.<ref>[http://hilo.hawaii.edu/~nat_haz/vog/media/VogAndLazeSeminar_Abstracts_29July1991.pdf HOW VOG IS MADE: A PHOTOGRAPHIC PERSPECTIVE] {{Webarchive|url=https://web.archive.org/web/20171101215658/http://hilo.hawaii.edu/~nat_haz/vog/media/VogAndLazeSeminar_Abstracts_29July1991.pdf |date=2017-11-01 }}, ''Vog and Laze Seminar'' (July 29, 1991)</ref>
