A few examples of such lies are presented at the very bottom of this page.For each dating or chronological method there is a link in the box at right to take you to that section of this page.These periods form elements of a hierarchy of divisions into which geologists have split the Earth's history.

You might imagine the magnetic field is a timeless, constant aspect of life on Earth, and to some extent you would be right. Every so often – on the order of several hundred thousand years or so – the magnetic field has flipped. And when the field flips it also tends to become very weak.Please remember that all dating methods, even those termed "absolute," are subject to margins of error. That is a very small amount of possible error range. Modern studies almost always use two or more methods to confirm dating work and to build confidence in the results obtained.Overview of Methods Superposition Stratigraphy Dendrochronology Radiocarbon C14 Radiometric Dating Methods Obsidian Hydration Dating Paleomagnetic/Archaeomagnetic Luminescence Dating Methods Amino Acid Racemization Fission-track Dating Ice Cores Varves Pollens Corals Cation Ratio Fluorine Dating Patination Oxidizable Carbon Ratio Electron Spin Resonance Cosmic-ray Exposure Dating This is an excellent overview of dating methodologies, and is a chapter in a textbook on Archaeology.Chronological sequence is all that is really required.However, human beings love to see factual precision, and we want to know how old something is.

There, you will find a brief description of the method, plus links to take you to other webpages with more extensive information.
