How Is Radioactive Dating Used to Determine the Age of an Object?

A Growth ring is the ring of growth found in some living organisms, such as trees. Some animals such as shells and corals also have annual growth rings. Counting the growth rings shows how old the organism is, or was when it stopped growing. For example, the growth rings in furniture, walls and other wooden items can be counted. Tree rings grow under the bark , and the bark is pushed out while the tree is growing.

Radiocarbon dating was invented in the late s, and in the many decades since, archaeologists have discovered wiggles in the radiocarbon curve—because atmospheric carbon has been found to fluctuate over time. Adjustments to that curve to correct for the wiggles "wiggles" really is the scientific term used by the researchers are called calibrations. Radiocarbon dating is one of the best known archaeological dating tools available to scientists, and most people have at least heard of it. But there are a lot of misconceptions about how radiocarbon works and how reliable a technique it is; this article will attempt to clear them up. All living things exchange the gas Carbon 14 abbreviated C 14 , 14C, and, most often, 14 C with the environment around them—animals and plants exchange Carbon 14 with the atmosphere, while fish and corals exchange carbon with dissolved 14 C in sea and lake water.
