Because of their organic origin
Natural gas and petroleum ARE fossil fuels.
Coal, petroleum,and natural gas, are called fossil fuels because they were formed millions of years ago, during the Carboniferous period.
Natural gas, coal and oil are the three main fossil fuels. Anthracite, petroleum, diesel and many other derivatives come from these.
A resource formed mainly from the remains of microscopic-sized marine organisms buried beneath the ground petroleum. The kind of energy produced when billions of atomic nuclei from uranium are split apart in a fission reaction is nuclear.
I believe the term "fossil fuels" is used for things that burn, in a chemical reaction - like coal and petroleum. Also, "fossil fuels" implies that the fuel is the remainder of fossils - as is believed to be the case with petroleum and coal.I believe the term "fossil fuels" is used for things that burn, in a chemical reaction - like coal and petroleum.

Natural gas and petroleum ARE fossil fuels.
Fossil fuel. Also, natural gas is in the category of fossil fuels.
Petroleum, coal, and natural gas are a few types of fossil fuels
Coal, petroleum,and natural gas, are called fossil fuels because they were formed millions of years ago, during the Carboniferous period.
They are called petroleum.
The fossil fuels, all of which are non-renewable, are petroleum, coal, and natural gas.
The known fossil fuels are coal, petroleum, natural gas, lignite, bitumen and peat
Non-renewable fossil fuels are: * coal * crude oil (Petroleum) * natural gas
