**What** is **Carbon** **Dating**? - Chemistry for Kids Mocomi At hh geomagnetic latitudes, the *carbon*-14 spreads evenly throughout the atmosphere and reacts with oxygen to form *carbon* dioxide. How do we know how old a fossil is? We use *carbon*, as every living being has *carbon*. *Carbon* *dating*, also known as radiocarbon *dating*, is a method of estimating the age of *carbon*-bearing materials up to 60,000 years. However, it is also used to *determine* ages of rocks, plants, trees, etc.

Is **carbon** **dating** a reliable method for determining the age of things? In addition, there are trace amounts of the unstable isotope **carbon**-14 (14C) on Earth. First, *carbon* *dating* only works on matter that was once alive, and it only *determines* the approximate date of death for that sample. Most archaeological items can’t be directly *carbon* dated, so their *dating* is based on testing done on nearby objects or materials.

**Carbon**-14 **dating** can **determine** the age So, using *carbon* *dating* for fossils older than 60,000 years is unreliable. After reading this section you will be able to do the following Describe why *carbon* can be found in all living organisms. Explain how *carbon* can help *determine* the.

**What** is **Carbon** **Dating**? NOSAMS By about ten half-lives, or 58,000 years, the amount of *carbon*-14 left in the fossil is very little- about 1/1000 of the orinal number of *carbon*-14 atoms in the fossil. Radioactive decay of naturally occurring and human generated 14C allows us to *determine* age by measuring the amount of. *What* is *Carbon* *Dating*? *Carbon* is one.

How is *carbon* *dating* done? So, every living thing is constantly exchanging *carbon*-14 with its environment as long as it lives. The *carbon* in its body will remain until it decomposes or fossilizes. It must be 1 *carbon* 14 half-life or 5730 years old.' This is the basic idea behind *carbon* *dating*. So in the real world, looking at a sample like say a bone dug up by an archaeologist, how do we know how much *carbon* 14 we started with.
