About Terri Rojas definition of numerical dating
A planet from the Greek planete means "wanderer" or more forcefully "vagrant, tramp" is an object in orbit around a definition of numerical dating that is not a star in its own right. Much like "continent," "planet" is a word without a precise definition, with history and culture playing as much of a role as geology and astrophysics. This is a "living glossary". This means that the glossary may grow every week as individuals submit new entries. The Wrong Word Dictionary:
Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon , in which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay. Together with stratigraphic principles , radiometric dating methods are used in geochronology to establish the geologic time scale. By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change.

Absolute dating is the process of determining an age on a specified chronology in archaeology and geology. Some scientists prefer the terms chronometric or calendar datingas use of the word "absolute" implies an unwarranted certainty of accuracy. In archaeology, absolute dating is usually definition of numerical dating on the physical, chemical, and life properties of the materials of artifacts, buildings, or other items that have been modified by humans and by historical associations with materials with known dates coins and written history. Techniques include tree rings in timbers, radiocarbon dating of wood or bones, and trapped-charge dating methods such as thermoluminescence dating of glazed ceramics. In historical geologythe primary methods of absolute dating involve using the radioactive decay of elements trapped in rocks or minerals, including isotope systems from very young radiocarbon dating with 14 C to systems such as uranium—lead dating that allow acquisition of absolute ages for some of the oldest rocks on earth. Radiometric dating is based on the known and constant rate of decay of radioactive isotopes into their radiogenic daughter isotopes.
