Radiometric Dating and the Geologic Time Scale, The Talk Origins Archive. Provides brief overview of (1) relative dating and stratigraphic methods, (2) absolute dating and radiometric dating, including a table with parent to daughter isotopes and half lives of those isotopes commonly used in radiometric dating, (3) paleomagnetics and (4) geologic time. Includes tables of common radioactive parent isotopes and their stable daughter products, and half lives of common radioactive isotopes.
The majority of the lesson focuses on radiometric dating, including an activity where students date their own "rocks and fossils".adaptation: Any heritable characteristic of an organism that improves its ability to survive and reproduce in its environment.Also used to describe the process of genetic change within a population, as influenced by natural selection.The site provides background information about stratigraphic principles and relative time, biostratigraphy (using fossils for relative dating), and radiometric dating. The site also provides fact sheets on the age of the Earth and isochron dating. However, rocks and other objects in nature do not give off such obvious clues about how long they have been around.
So, we rely on radiometric dating to calculate their ages.If such a behavior is even partly genetically determined, it will tend to become widespread in the population.Then, even if circumstances change such that it no longer provides any survival or reproductive advantage, the behavior will still tend to be exhibited -- unless it becomes positively disadvantageous in the new environment.Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.
