- Heat and pressure compress the mud and carbon over millions of years, forming sedimentary rock such as shale. In special cases, when dead plant matter builds up faster than it can decay, layers of organic carbon become oil, coal, or natural gas instead of sedimentary rock like shale.Learn more:Heat and pressure compress the mud and carbon over millions of years, forming sedimentary rock such as shale. In special cases, when dead plant matter builds up faster than it can decay, layers of organic carbon become oil, coal, or natural gas instead of sedimentary rock like shale.www.earthobservatory.nasa.gov/features/CarbonC…Carbon-14 is a rare version of carbon with eight neutrons. It is radioactive and decays over time. When carbon-14 decays, a neutron turns into a proton and it loses an electron to become nitrogen-14. The length of time it will take for half the amount of carbon-14 to decay is known as its half-life.www.pbs.org/wgbh/nova/education/physics/radioac…See more
