Rated 3.98/5 based on 671 customer reviews

Love-hungry teenagers and archaeologists agree: dating is hard.

But while the difficulties of single life may be intractable, the challenge of determining the age of prehistoric artifacts and fossils is greatly aided by measuring certain radioactive isotopes.

A portion of the material is ground up and a measurement is made of the ratio of radioactive “parent” atoms to the decomposition products.

Age estimates which are obviously wrong or contradictory are sometimes produced.

Carbon-14 is also passed onto the animals that eat those plants.

After death the amount of carbon-14 in the organic specimen decreases very regularly as the molecules decay.

Similarly, the radioactive element uranium decomposes into lead and some other elements.

How are these processes used to estimate the age of rocks?

The lowest age defended on a scientific basis is in the 6 to 10 thousand year range.Scientists have proposed numerous age estimation methods.Most systems promoted by Evolutionists involve radioactivity.Until this century, relative dating was the only technique for identifying the age of a truly ancient object.By examining the object's relation to layers of deposits in the area, and by comparing the object to others found at the site, archaeologists can estimate when the object arrived at the site.
