These radioactive elements constitute independent clocks that allow geologists to determine the age of the rocks in which they occur.

Most scientists and many Christians believe that the radiometric dating methods prove that the earth is 4.5 billion years old.

The textbooks speak of the radiometric dating techniques, and the dates themselves, as factual information.

Relative age dating also means paying attention to crosscutting relationships.

Say for example that a volcanic dike, or a fault, cuts across several sedimentary layers, or maybe through another volcanic rock type.

As radioactive Parent atoms decay to stable daughter atoms (as uranium decays to lead) each disintegration results in one more atom of the daughter than was initially present and one less atom of the parent.
