We hear so much about “fossil fuels” these days, but what is meant by this expression?  Fossil fuels are formed during millions and/or hundreds of millions of years, through extreme heat and temperature exerted on organic materials (living things) such as plants and animals. Fossil fuels range in form from extremely volatile, such as gases like methane, through liquids such as petroleum, up to totally non-volatile materials like anthracite coal.
