Simple but not tell us when sedimentary rock layers using relative-age dating. In relative dating, mostly the common sense principles are applied, and it is told that which artifact or object is older than the other one. Dendrochronology can date the time at which tree rings were formed, in many types of wood, to the exact calendar year. Why do you think it is a good element to use to date fossils and some rock?
This tells them how many times half the parent atoms turned into daughter atoms. Geological history of Earth Timeline of geology. By measuring the amount of carbon remaining, scientists can pinpoint the exact date of the organism's death.
