How relative dating works Sexbrazil
Other creationists have focused on instances in which radiometric dating seems to yield incorrect results.In most instances, these efforts are flawed because the authors have misunderstood or misrepresented the data they attempt to analyze (for example, Woodmorappe 1979; Morris HM 1985; Morris JD 1994).Using relative dating the fossil is compared to something for which an age is already known.For example if you have a fossil trilobite and it was found in the Wheeler Formation.
The majority of the time fossils are dated using relative dating techniques.
Radiometric dating works by determining the ratio of the number of isotopes of an element and the number of isotopes the element it turns into over time.
Since the rate at which certain elements decay and turn into different elements is understood, scientists are able to calculate the age of substances.
The elements embedded in the Earth's crust decay over time because they are very unstable.
When these elements decay and turn into other elements, scientists measure the difference between the original element and its decayed form.
