most abundant fossil fuel in the world

• fossil fuels

• coal

• acid precipitation

• oil refinery

Oil and natural gas are formed from the

• migration of complex carbohydrate molecules to nonporous rock formations.

• decay of tiny marine organisms that accumulated on the bottom of the ocean millions of years ago.

• burning of high-sulfur, low-grade uranium.

• decay of plants that lived in swamps hundreds of thousands of years ago.

Inside the combustion chamber of a coal-fired power plant

• steam is directed against turbine blades and causes the blades to turn.

• the turbine sets the generator in motion.

• electricity is generated.

• burning fossil fuels releases energy in the form of heat.
