Methane (CH4) is a simple hydrocarbon gas present in the atmosphere or underground as part of natural gas fossil fuel. A group of single-celled organisms, called archaeans, can produce methane by means of different mechanisms.
State the name of the process by which methane is produced.
Archaeans can produce methane in a range of different environments.
List two of these environments where methane can be produced.
When methane is released into the atmosphere, it is involved in the following reaction:
Identify the type of reaction that is illustrated above.
Carbon compounds, such as methane, can become trapped in peat which can be burned as fuel.
Briefly describe how peat is formed.
