Definitions

Natural gas is a hydrocarbon gas mixture consisting primarily of methane, but commonly includes varying amounts of other higher alkanes and sometimes a usually lesser percentage of carbon dioxide, nitrogen, and/or hydrogen sulfide. Natural gas is a fossil fuel formed when layers of buried plants and gases are exposed to intense heat and pressure over thousands of years.
