Ready for some action? You've got energy to burn. Feeling cramped after all those centuries? Let loose, then float free in the ATMOSPHERE!

Every hour of every day society depends on energy from forms of carbon that take millenia to make. We drill oil, mine coal, frack natural gas. We extract these fossil fuels from deep in the earth and refine them into combustible fuels. We burn these to move planes, trains and cars, to heat our homes and cook our food, to generate electricity to run our computers and lights. Burning also returns that long sequestered carbon to the atmosphere as a result.
Plastics and other polymers can be made from refining petroleum. Your entire refrigerator may have come from ancient swamps.
BEGIN AS: Hydrocarbon. BECOME: Carbon Dioxide.
2 C8H18 + 25 O2 => 16 CO2 + 18 H2O
Octane + Oxygen => Carbon Dioxide + Water + Energy
Hydrocarbons release energy in the process of combustion.

What's the rush? Why not stick around for another million years or so? Take your time. Stay as ROCK.
Just WAIT AROUND!
Carbon stays in rock, oil, minerals and salts for millions and millions of year.
After millions of years of sub-oceanic-floor movement the remains of plants and animals trapped in sedimentary rock are forced deep into the earth's fiery core. This organic debris heats up under great pressure, breaks down, then reforms into long chains of carbon and hydrogen known as hydrocarbons. Many different forms of hydrocarbons are made from the bonding of two simple constituents, only hydrogen and carbon. Methane, CH4 is the simplest hydrocarbon.

You are Carbon in Rock
Heat and pressure sure can add up over time. Yet, we endure in the face of eternity, dwelling below the hurly-burly of ocean and earth surfaces.
99% of all the carbon on earth is stored in the earth's crust. Millions, even hundreds of millions of years may pass before carbon moves along the its journey. The immense scale of time taken in this part of the carbon cycle makes it virtually permanent storage.
Without human intervention, the carbon in rock can re-enter the carbon cycle violently through volcanic eruptions or more gradually through vents, geysers and hot springs, or even more gradually through weathering. Human intervention is a fast track to the atmosphere, geologically speaking.
Iron: 32.1%, Oxygen: 30.1%, Silicon: 15.1%, Sulfur: 2.9%, Magnesium: 13.9%, Nickel: 1.8%, Calcium: 1.5%, Aluminum: 1.4%, Other: 1.2%
The composition of the earth's surface contains only a small fraction of carbon.
