# Compare radioactive dating to relative dating

Radioactive dating of rock samples determines the age of rocks from the time it was formed.

Geologist determine the age of rocks using radioactive dating.

Relative dating, meanwhile, measures the order of past events, without determining their absolute age. Radioactive dating is taking an element from a sample with a known rate of decay and invert the equation to find the time(date) from which it started to decay.

Relative dating determines the period of time from which an object come from based on technology, soil, anthropology, etc.

Both are attempting to get information on the history of events.

Tools like radiometric dating use radioactive isotopes and known decay rates…

It is the difference between sand running out of an hour glass and determining what time it is by how much sand is left. If you can determine how much of that radioactive isotope ought to have been in a sample at the start and you can measure how much is left, you can tell how much time has passed.

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.

We're sorry, this computer has been flagged for suspicious activity.

Relative age dating is a scientific process of evaluation used to determine the relative order of past events, but does not determine the absolute age of an object or date of an event.

Both relative dating and absolute dating are complimentary tools tools used to assign temporal characteristics to a sequence of events.

Carbon dating is one type of radiometric dating, there are others.

Carbon dating uses the carbon-14 isotope, with a half life of about 5700 years.

Relative dating helps determine what came first and what followed, but doesn't help determine actual age.

There ARE rules, however, and everybody is expected to follow them.
