How does carbon dating work with objects?
All living things absorb C14 carbon while they are alive on earth. When they die, they stop absorbing C14 and it begins to decay. Radiocarbon dating measures the amount of carbon-14 left in human or plant remains, and then scientists can estimate the amount of time the thing has been dead
What method of archaeological dating determines an artifacts age in relation to other objects?
The method is called carbon dating.
What do you use to measure years?
you could use the carbon-14 method or the uranium-lead method
List a range of items that can be dated by isotope carbon 14?
It is not that simple. Carbon 14 (C14) is created in the upper atmosphere by the action of cosmic rays on Nitrogen atoms. There is not much of it, C14 occurs in trace amounts, only making up as much as 1 part per trillion (0.0000000001%) of the carbon on the Earth. This amount of C14 is in balance, the amount created in the upper atmosphere balances the amount lost by the natural radioactive decay of the isotope. All living things on earth, are made of chemicals that include carbon and, while living, the amount of C14 in them is in balance with the amount of C14 in the atmosphere. However when a living thing dies it no longer mixes the carbon in its body with that of the atmosphere and thus the amount of C14 it contains begins to reduce to levels below that found in the atmosphere because the C14 decays radioactively. Thus items to be dated using C14 must contain carbon (wood, charcoal, hair and bones are good) and must have remained undisturbed since the organisms death. Also C14 decays rather quickly and is therefore only good for dating items that are less than about 60,000 years old.
Does volcanic ash contain C14?
No. Volcanic ash is composed largely of silica and metal oxides, with little or no carbon. The materal that the ash originates from has been inside the earth for millions, if not billions of years, so if there were any C14 in it to begin with, it would have decayed into immeasureably small quantities.
Only good for dating objects as far back as about 4000 years?
Carbon dating is a radiometric dating method that can accurately determine the age of organic materials up to about 50,000 years old. It works by measuring the decay of carbon-14 isotopes in the material. After 40,000 years, the remaining carbon-14 levels are too low to accurately date the sample.
Is carbon dating is a type of technology currently used to study the past?
Yes, measurements of the ratio of carbon-14 (radioactive) to carbon-12 (nonradioactive) in a sample is used as a type of clock to determine the age of the sample. BTW, ever wonder why C14 dating works? Presumably, the organism is eating a constant proportion of C14 while it lives. So when it dies, the C14 is not being replenished. Sounds awful fishy to me, but what else is there? I would have like the process better if the organism were making C14 at a constant rate-- but alas, not so.
What is the difference between c 12 and c 14?
C12 and C14 are isotopes of the Element Carbon. C12 is the most abundant of all which is 99% of all the Carbon on earth while C14 is only 0.0000000001% (trace amount). C12 has a Atomic Number of 12. It has 6 Protons and 6 Neutrons. C14 has a Atomic Number of 14. It has 6 Protons and 8 Neutrons. C14 is radioactive in nature. It is used for carbon dating.

What type of dating involves the use of radioactive elements and half-lives?
Radioactive decay may be used in carbon dating, testing for the amounts of a radioactive carbon isotope (C14) in the remains of some organism. C14 obviously only works on organic material which was once alive, such as wood or bone. Because C14 has a very short half life, less than 6000 years, it does not work on material much over 60,000 years (about ten half lives). Potassium/Argon is another useful set of isotopes that can yield the ages of rocks and inorganic matter far older--many millions of years old.
What are the Advantages of poaching method?
whats the advantages?
Method of dating ancient remains?
carbon dating
What method of archaeological dating determines an artifacts age in relation to other objects?
The method is called carbon dating.
A researcher who uses carbon dating on anciet items?
The half life of C14 is about 5700 years, so items that are a few multiples of this time are suitable for carbon14 dating. Most archaeological items are suitable, and some young fossils.
Which radiometric-dating method would be most apprioate for dating artifacts found at effi gy mounds?
Carbon-14 dating would be the most appropriate radiometric dating method for dating artifacts found at effigy mounds. This method is commonly used for dating organic materials such as wood, charcoal, or bone, which are typically found in archaeological sites like effigy mounds.
