Continue Reading Relative dating observes the placement of fossils and rock in layers known as strata.
Basically, fossils and rock found in lower strata are older than those found in higher strata because lower objects must have been deposited first, while higher objects were deposited last.
To get to that point, there is also a historical discussion and description of non-radiometric dating methods.
The example used here contrasts sharply with the way conventional scientific dating methods are characterized by some critics (for example, refer to discussion in "Common Creationist Criticisms of Mainstream Dating Methods" in the Age of the Earth FAQ and Isochron Dating FAQ).
During the 19th century, and even well into the twentieth, geological chronology was very crude.
Each chapter will include a few questions designed to test your knowledge of material covered in the chapter and in the Internet-based resources. Astronomy and Geology, working on scientific data built up over the last two centuries or so, assumes the Earth to be very ancient, more in keeping with the eastern than the western (Graeco-Judeo-Christian) perspectives.However, whereas the Eastern perspective is (like the Greek) cyclic, the Western scientific understanding is strictly linear and evolutionary.I thought it would be useful to present an example where the geology is simple, and unsurprisingly, the method does work well, to show the quality of data that would have to be invalidated before a major revision of the geologic time scale could be accepted by conventional scientists.Geochronologists do not claim that radiometric dating is foolproof (no scientific method is), but it does work reliably for most samples.
