What is locked up' carbon?

Locked-up carbon refers to carbon that is stored or sequestered in forests, soil, ocean sediments, or other natural systems, reducing the amount of carbon dioxide in the atmosphere. This stored carbon helps to mitigate the impacts of climate change by preventing it from contributing to the greenhouse effect.


Carbon in the atmosphere is most often found as which of the following compounds?

List the compounds so I can answer your question. I would imagine Carbon Dioxide and Carbon Monoxide would be the first 2.


If you could break up a carbon dioxide molecule would you still have carbon dioxide?

No, breaking up a carbon dioxide molecule into its constituent atoms (carbon and oxygen) would result in separate carbon and oxygen atoms. The molecular structure and properties of carbon dioxide would no longer exist.


What gases make up carbon dioxide?

One atom of carbon and two atoms of oxygen equal CO2 (carbon dioxide).


How did all the carbon on earth get locked up?

Carbon on Earth became locked up through various processes over millions of years. This includes photosynthesis by plants converting carbon dioxide into organic matter, which eventually gets buried and turned into fossil fuels. Other processes like shell formation by marine organisms and volcanic activity also contribute to carbon storage in the Earth's crust.


Is carbon dioxide made up of three elements?

no,carbon dioxide is made up of oxygen and carbon


Why is there is so little carbon dioxide and more oxygen in Earth's atmosphere?

Algae and later plants carried out photosynthesis, which uses sunlight to convert water and carbon dioxide into sugar and oxygen. This process removed carbon dioxide from the air and added oxygen. Additional carbon dioxide was removed and locked away in carbonate rocks such as limestone.


Does carbon dioxide have copper in it?

yes it does the carbon dioxide is supposed to be heated up copper carbonate


Does the circulatory system take up carbon dioxide or oxygen?

The circulatory system takes up oxygen, and releases carbon dioxide.


Is there more nitrogen or carbon dioxide in earth's atmosphere?

There is much more nitrogen in earth's atmosphere than carbon dioxide. Nitrogen forms about 79%, while carbon dioxide makes up about 0.04%.


What compound is made up of carbon and oxygen?

carbon monoxide carbon dioxide


When trees die do they release stored up carbon dioxide?

Well, trees don't really store carbon dioxide; they use the carbon dioxide directly to produce sugars during the Calvin cycle. When decomposers eat up those sugars, they release the carbon in the sugars in the form of carbon dioxide.
