What is the use of radiometric dating
But Earth’s layers of rock did not give up the secret of Earth’s age easily. However, from working with layer upon layer of rock laid down on Earth over long time spans, early 20th century scientists came to believe Earth not of atoms of one chemical element into another.
They led to the discovery that certain very heavy elements could decay into lighter elements – such as uranium decaying into lead.
Scientists tried to determine Earth’s age via our planet’s layers of rock, which must have been built over time.
You’ve seen these rock layers if you’ve ever observed a cut-away section of a mountain, perhaps because a highway runs through it. In the early part of the 20th century, scientists still weren’t sure.

This article summarizes the conclusions of the three Q&A sections below, and sketches some promising directions for an intellectually honest common ground between science and religion.These articles are updated periodically as new research results and scholarship become available.Detailed references are given in all cases, with web links where available, and all references are listed in an extensive bibliography.Sometimes only one method is possible, reducing the confidence researchers have in the results. “They’re based on ‘it’s that old because I say so,’ a popular approach by some of my older colleagues,” says Shea, laughing, “though I find I like it myself as I get more gray hair.” Kidding aside, dating a find is crucial for understanding its significance and relation to other fossils or artifacts.Methods fall into one of two categories: relative or absolute.
