This online version of their informative booklet contains short, content explanations about relative time, major geologic time divisions, index fossils for use in age dating, radiometric dating and the age of the earth.
The Carbon-14 method measures the amount of radioactive carbon-14 in a previously living artifact.Who's to say that the rocks a particular scientist is studying have not been displaced from their original positions?
