Getting Into the Fossil Record / Focus Questions Key The impacts of fossil fuel consumption continue to have a detrimental effect on many aspects of the environment. Slow geological processes, including the formation of sedimentary rock and fossil fuels, contribute to the carbon cycle over long timescales. The body is usually exposed to air and water with a lot of oxygen, so it decomposes rapidly.The animal is likely to be fossilized only if it is buried soon after it dies (or when it is buried alive!). The burning of this fossil material returns this carbon back into atmosphere as carbon dioxide, at a rate that is hundreds to thousands of times faster than it took to bury, and much faster than can be removed by the carbon cycle.
