Free 5-day trial Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes.

Ice core sampling normally uses the assumption that the ring bands observed represents years.

One known example where this assumption was used is very misleading.

Seriation uses the assumption that once a tool was developed, its use would become more widespread.

Stratigraphy uses the assumption that higher layers or strata were laid down after lower layers.

Together with stratigraphic principles, radiometric dating methods are used in geochronology to establish the geological time scale.The topic of radiometric dating has received some of the most vicious attacks by young earth creation science theorists.However, none of the criticisms of young earth creationists have any scientific merit.All ordinary matter is made up of combinations of chemical elements, each with its own atomic number, indicating the number of protons in the atomic nucleus.

Additionally, elements may exist in different isotopes, with each isotope of an element differing in the number of neutrons in the nucleus.

Radiometric dating remains a reliable scientific method.
