About me:
Geologists do not use carbon-based radiometric dating to determine the age of rocks. Carbon dating only works for objects that are younger than about 50, years, and most rocks of interest are older than that. Carbon dating is used by archeologists to date trees, plants, and animal remains; as well as human artifacts made from wood and leather; because why can carbon dating be used on rocks items are generally younger than 50, years. Carbon is found in different forms in the environment — mainly in the stable form of carbon and the unstable form of carbon Over time, carbon decays radioactively and turns into nitrogen. A living organism takes in both carbon and carbon from the environment in the same relative proportion that they existed naturally.

The most widely known form of radiometric dating is carbon dating. This is what archaeologists use to determine the age of human-made artifacts. But carbon dating won't work on dinosaur bones. The half-life of carbon is only 5, years, so carbon dating is only effective on samples that are less than 50, years why can carbon dating be used on rocks. Dinosaur bones, on the other hand, are millions of years old -- some fossils are billions of years old. To determine the ages of these specimens, scientists need an isotope with a very long half-life.

It is not possible to carbon date rocks. Carbon 14 dating is based on the absorption of atmospheric carbon by living things. When the thing dies it no longer takes in carbon from the atmosphere through processes such as eating or respiration and levels of C14 in the body deplete due to the natural process of radioactive decay.

More about why can carbon dating be used on rocks:
Carbon dating is used to determine the age of biological artifacts up to 50, years old. This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils like those of the dinosaurs alleged to be millions of years old. This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers. Carbon dating has been used successfully on the Dead Sea Scrolls, Minoan ruins and tombs of the pharaohs among other things. Carbon is a radioactive isotope of carbon. The half-life of why can carbon dating be used on rocks is approximately 5, years.

Radioactive dating is a method of dating rocks and minerals using radioactive isotopes. This method is useful for igneous and metamorphic rocks, which cannot be dated by the stratigraphic correlation method used for sedimentary rocks. Over naturally-occurring isotopes are known. Some do not change with time and form stable isotopes i. The why can carbon dating be used on rocks or more commonly known radioactive isotopes break down by radioactive decay into other isotopes. Radioactive decay is a natural process and comes from the atomic nucleus becoming unstable and releasing bits and pieces. These are released as radioactive particles there are many types. This decay process leads to a more balanced nucleus and when the number of protons and neutrons balance, the atom becomes stable.

Yes, I want to follow Jesus. I am a follower of Jesus. I still have questions. The answer is no, we can't. The reason is twofold. Gerald Aardsma explains, "Radiocarbon is not used to date the age of rocks or to determine the age of the earth.
