Radiocarbon dating involves determining the age of an ancient fossil or specimen by measuring its carbon-14 content.
Carbon-14, or radiocarbon, is a naturally occurring radioactive isotope that forms when cosmic rays in the upper atmosphere strike nitrogen molecules, which then oxidize to become carbon dioxide.
Relative dating stems from the idea that something is younger or older relative to something else.
The thing to remember about half-life is that it is a probability.For example, Christian time counts the birth of Christ as the beginning, AD 1 (Anno Domini); everything that occurred before Christ is counted backwards from AD as BC (Before Christ).The Greeks consider the first Olympic Games as the beginning or 776 BC.Although relative dating can work well in certain areas, several problems arise.Stable and Unstable Isotopes Elements can be made up of different isotopes.
