Answer:

The age of a rock in years is its absolute age. The main evidence for absolute age comes from radiometric dating methods, such as carbon-14 dating. These methods depend on radioactive decay. Radioactive decay is the breakdown of unstable isotopes into stable elements.

Explanation:

Amount of Carbon - 14 helps determine the absolute age of rocks and fossils.

The quantity of carbon-14 left in a fossil creature therefore shows how long it has been since it died, giving an absolute age estimate.

The isotope can also be employed as a tracer to track the progress of certain carbon molecules through biochemical processes. The quantity of carbon-14 present in a historical specimen, such as a tree, is used to determine the specimen's date in carbon-14 dating.
