Marsh gas is a gas that is primarily made up of methane, and is also known as biogas, swamp gas, or bog gas:
Composition:
Marsh gas is a mixture of methane, hydrogen sulfide, carbon dioxide, and trace amounts of phosphine.
Formation:
Marsh gas is produced when organic matter breaks down in waterlogged soils through anaerobic decomposition.
Location:
Marsh gas is found at the surface of marshes, which are wetlands where water covers the ground for a long time.
Effects:
Marsh gas can contribute to the greenhouse effect by diffusing into the atmosphere. It can also ignite spontaneously, creating a phenomenon known as “will o’ the wisp” or “ignis fatuus”.
The correct answer to the question: "The marsh gas is: _________?" is "Methane".
