Difference between radioactive decay radiometric dating
It is more accurate for shorter time periods (e.g., hundreds of years) during which control variables are less likely to change.
There are a number of implausible assumptions involved in radiometric dating with respect to long time periods.
Fluorine analysis is limited by the fact that it can only be used to ascertain the relative ages of bones from the same site.
Radiometric dating was developed later than relative dating, and requires more advanced technology.
By learning how relative and radiometric dating methods work, you can better understand how science uncovers the history of our world.
One of the major radiometric dating techniques used today measures the decay of potassium-40.The degrees of error in each method can make establishing chronologies tricky.In most cases, geologists, paleontologists and anthropologists cross-correlate the results of multiple dating methods for more accurate and tested conclusions.K/Ar dating only works on inorganic material, however. To date organic as well as inorganic material, scientists often use the carbon-14, or radiocarbon, dating technique.Like K/Ar dating, radiocarbon dating relies on the measurement of the decay of one isotope into another.
