Is carbon dating used to measure the age of rocks

These artifacts have gone through many carbon-14 half-lives, and the amount of carbon-14 remaining in them is miniscule and very difficult to detect.

Also, many fossils are contaminated with carbon from the environment during collection or preservation procedures.

Scientists attempt to check the accuracy of carbon dating by comparing carbon dating data to data from other dating methods.

Scientists now realize that production of carbon-14 has not been constant over the years, but has changed as the radiation from the sun has fluctuated.

Nuclear tests, nuclear reactors and the use of nuclear weapons have also changed the composition of radioisotopes in the air over the last few decades.

Other methods scientists use include counting rock layers and tree rings.

When scientists first began to compare carbon dating data to data from tree rings, they found carbon dating provided "too-young" estimates of artifact age.The ratio of the original isotope and its decay product determines how many half-lives have occurred since the sample formed.A half-life measures the time it takes for one half of a radio isotope's atoms to break down into another element.Some of these other isotopes include: back to the last global catastrophe (i.e.the global Flood of 2,348 BC) as global catastrophes reset all the radiometric/atomic “clocks” by invalidating the evolutionist’s main dating assumption that there have never been any global catastrophes.For biological objects older than 50,000 years, scientists use radioactive dating to determine the age of rocks surrounding where the material was found.
