    WebAbsolute Age. The standard geologic time scale was devised according to relative time relationships observed in rocks across the world. Determining the actual ages of these time spans, and thus establishing the beginning and ending dates of geologic eons, eras, periods, and epochs, became possible with the discovery of radioactivity.

    WebOct 19, 2023 · As advances in chemistry, geology, and physics continued, scientists found a method by which the absolute age—an actual number of years—of a rock or mineral sample could be determined. This method is called radiometric dating, and it involves the decay, or breakdown, of radioactive elements.

    WebOct 19, 2023 · In 1862, a famous Irish physicist and mathematician, Lord Kelvin, estimated that Earth was between 20-million and 400-million years old. But even an age of 400 million years would make the planet quite young compared to the rest of the universe. Lord Kelvin based his conclusion on a calculation.
