Carbon stored in the bodies of living organisms moves into rocks primarily through a process called sedimentation and fossilization. When organisms die, their bodies can become buried by sediment, such as mud and sand, especially in aquatic environments. Over time, the pressure and heat from the overlying sediments cause the organic material to undergo chemical changes, transforming it into fossil fuels like coal, oil, and natural gas, or into carbonate rocks such as limestone. This process effectively locks carbon away in geological formations, thereby sequestering it in the Earth's crust.
