- This fire began in a forest.
Long before the coal, living plants captured energy from sunlight.
- Leaves made the first deposit.
Photosynthesis turned sunlight into chemical energy in plant matter.
- The forest went underground.
Burial, heat and pressure transformed plant remains over millions of years.
- A flame unlocks the energy.
Burning coal releases stored chemical energy as heat and light.
- Deep time. A present-day consequence.
The energy becomes heat. Carbon in the coal also becomes carbon dioxide.
