Radioactive decay is a spontaneous process in which an isotope (the parent) loses particles from its nucleus to form an isotope of a new element (the daughter).

The rate of decay is conveniently expressed in terms of an isotope's half-life, or the time it takes for one-half of a particular radioactive isotope in a sample to decay.

Uniformitarian geologists consider this form of dating strong evidence that the Earth is billions of years old.

ANSWER: In relative dating, something is determined to be older or younger than something else without determining an exact age.According to theory, the sample starts out with daughter isotopes present at constant ratios in relation to one another, but with the parent isotope, the ratio is arbitrary.As a result it forms a straight horizontal line on a graph.Most absolute dating techniques utilize predetermined rates of radioactive decay to calculate the elapsed period of time. stratigraphy), absolute dating is a quantitative measurement allowing determination of a specific time, rather than relative.Absolute dating provides a numerical age for the material tested, while relative dating can only provide a sequence of age.
