The chemical formula for methane is CH₄. Methane is a simple hydrocarbon consisting of one carbon atom bonded to four hydrogen atoms, and it is the primary component of natural gas. It is colorless, odorless, and flammable, making it an important energy source used for heating, electricity generation, and as a fuel for vehicles. Methane is also a potent greenhouse gas; it has a much higher heat-trapping ability compared to carbon dioxide, although it remains in the atmosphere for a shorter duration. Methane can be produced from both natural sources, such as wetlands, and human activities, including agriculture and fossil fuel extraction.
