Relative dating involves radioactive isotopes
The spontaneous decomposition is called radioactive decay.Relative dating of rock involves an approximation of age based on fossil evidence found in a rock formation.The Sun, obviously, is the brightest object in the sky when observed from Earth, so it has the lowest apparent magnitude value of -26.7.The faintest objects that a human eye can detect have apparent magnitudes of about 6.That is an essential part of radioactive carbon dating.Uranium, for instance has a has half life of 5,400 years.Relative dating, meanwhile, measures the order of past events, without determining their absolute age.Radiometric dating--the process of determining the age of rocks from the decay of their radioactive elements--has been in widespread use for over half a century.
This is done with many different radioactive isotopes of elements, each is good for a different age range.
Relative dating is used to determine the relative ages of geologic strata, artifacts, historical events, etc.
A radioactive isotope is an isotope whose nucleus tends to release particles, radiant energy, or both; Radioactive dating is a technique for determining the age of material by measuring the amount of a particular radioactive isotope the material contain.
Geologist determine the age of rocks using radioactive dating.
The radioactive dating relies on spontaneous decomposition into other element.

Another one would likely be tree-ring dating which only determines the age of trees by how many rings it has.
