Relative dating principles include

The study of fossils and the exploration of what they tell scientists about past climates and environments on Earth can be an interesting study for students of all ages.Teaching about Earth's history is a challenge for all teachers.Picture from Glen Canyon National Recreation Area, Utah.Relative dating is the science determining the relative order of past events, without necessarily determining their absolute age.

While digging the Somerset Coal Canal in southwest England, he found that fossils were always in the same order in the rock layers.In geology rock or superficial deposits, fossils and lithologies can be used to correlate one stratigraphic column with another.Prior to the discovery of radiometric dating which provided a means of absolute dating in the early 20th century, archaeologists and geologists were largely limited to the use of relative dating techniques to determine the geological events.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.
