-
Locked up carbon

Fossil fuels
Natural gas & oil
- The remains of dead organisms sunk to the bottom of oceans and lakes
- They were buried under sediments
- Over millions of years, the heat and pressure turned the remains into crude oil and natural gas
Coal
- dense forests in low-lying wetland areas became flooded.
- The lack of oxygen prevented oxidation from occuring
- Compression and heating over millions of years turned the wood into coal.
