This is why they are called ‘fossil’.  All these fuels are ‘carbon-based’ meaning they are consisting mainly of elements that contain carbon and hydrogen coming from these ancient animals and plants’ bodies. Oil is a fossil fuel in liquid form (where each molecule contains several carbon atoms), natural gas is fossil fuel in gaseous form (where each small molecule contains just 1 or 2 carbon atoms), and coal is fossil fuel in solid form (each molecule contains many carbon atoms).Continue reading
