Natural Gas
Vocabulary. Natural gas is a fossil fuel. Like other fossil fuels such as coal and oil, natural gas forms from the plants, animals, and microorganisms that lived millions of years ago. There are several different theories to explain how fossil fuels are formed. The most prevalent theory is that they form underground, under intense conditions.
