Carbon 14 dating archaeology

ANSWER: To understand how carbon 14 dating works, you first have to understand what carbon-14 is and what part it plays in our biosphere. As they live and grow and interact with their environments they consume more and more carbon.By far, the most abundant form of carbon is carbon-12.Because atmospheric carbon 14 arises at about the same rate that the atom decays, Earth's levels of carbon 14 have remained fairly constant.Once an organism is dead, however, no new carbon is actively absorbed by its tissues, and its carbon 14 gradually decays.

Because the ratio of carbon 12 to carbon 14 present in all living organisms is the same, and because the decay rate of carbon 14 is constant, the length of time that has passed since an organism has died can be calculated by comparing the ratio of carbon 12 to carbon 14 in its remains to the known ratio in living organisms. Our Living Language : In the late 1940s, American chemist Willard Libby developed a method for determining when the death of an organism had occurred.

This is not an example of the work written by our professional essay writers.

The science of archaeology has undeniably enriched mankind’s history and has helped to quench the quest to understand our past cultures in a better way.

Radiocarbon dating technique is primarily based on the radioactive decay of Carbon-14 isotope.

Developed by a team of researchers under the leadership of Dr.
