Radiometric Dating and the Geological Time Scale

The primary difference is that absolute dating assigns an actual time or age to an event or object. Relative dating simply says one is older than the other but no age is specified. Tools like radiometric dating allow some samples to be assigned a certain age to within some accuracy. Assigning a certain age or date is a form of absolute dating.

Dating methods and the age of the Earth - ppt video online download

To find their age, two major geological dating methods are used. These are called relative and absolute dating techniques. Absolute dating, also called numerical dating, arranges the historical remains in order of their ages. Whereas, relative dating arranges them in the geological order of their formation.

Pre/Post-Test Key

Radiometric dating provides numerical values for the age of an appropriate rock, usually expressed in millions of years. When a geologist collects a rock sample for radiometric age dating, or collects a fossil, there are independent constraints on the relative and numerical age of the resulting data.

What is Carbon (14C) Dating? Carbon Dating Definition

Absolute dating is the process of determining an age on a specified chronology in archaeology and geology. Some scientists prefer the terms chronometric or calendar dating, as use of the word "absolute" implies an unwarranted certainty of accuracy. Absolute dating provides a numerical age or range in contrast with relative.
