 Coal is formed from plant life buried in the Earth millions of years ago. Like Petroleum and natural gas, it is a carbon-based fossil fuel.  Coal is called a fossil fuel b â¦ ecause it was formed from the remains of vegetation that grew as long ago as 400 million years.
What is coal? Coal is a fossil fuel and is the altered remains of prehistoric vegetation that originally accumulated in swamps and peat bogs. The energy we get from coal today comes from the energy that plants absorbed from the sun millions of years ago. All living plants store solar energy through a process known as photosynthesis.
