How is carbon dioxide converted to fossil fuel?
How is carbon dioxide converted to fossil fuel?
After 60,000 years fossil fuel contains only carbon-12 (all of the carbon-14 has been converted to nitrogen) but the atmosphere still maintains a healthy mixture of the three isotopes. Since it takes millions of years to create fossil fuel, the carbon dioxide that is released into the atmosphere from the burning of fossil fuel would no carbon-14.
How does the burning of fossil fuels affect the atmosphere?
Since it takes millions of years to create fossil fuel, the carbon dioxide that is released into the atmosphere from the burning of fossil fuel would no carbon-14. If the burning of carbon-based fossil releases carbon dioxide into the atmosphere, the amount of carbon-14 isotope found in atmospheric carbon dioxide should decrease over time.
How is carbon dioxide released into the air?
Carbon dioxide is released into the air from combustion of fossil fuels, and from respiration by animals and plants
Where are the fossil fuels found in the atmosphere?
Fossil fuel reservoirs are composed of coal, oil or natural gas and over time these reservoirs are buried deep in the ocean floor or underground. The carbon atoms found in both the atmosphere and initially in fossil fuel contain all three carbon isotopes (carbon-12,…
How are fossil fuels released into the atmosphere?
Fossil fuels contain massive amounts of carbon and as long as they are buried deep within the earth, they don’t become part of the atmospheric carbon pool. It is only when these fuels are extracted from the earth and burned that the carbon is released into the air.

How does photosynthesis release oxygen to the atmosphere?
In green plants, photosynthesis separates carbon dioxide into molecular oxygen (which is released to the atmosphere), and carbon (which is stored in carbohydrates). But photosynthesis had already been around for at least 2.5 billion years. So what accounted for the sudden spike in oxygen during the Cambrian?
