Dating methodReport abuse Transcript of Relative Dating: The Age of Rock Layers Have you ever read a mystery book or watched a mystery movie. The results portray where erosion has taken place and rock layers are missing.
Physical features are studied to determine their relative ages. Geologists use radiocarbon to date such materials as wood and pollen trapped in sediment, which indicates the date of the sediment itself. Isotopes are important to geologists because each radioactive element decays at a constant rate, which is unique to that element. These rates of decay are known, so if you can measure the proportion of parent and daughter isotopes in rocks now, you can calculate when the rocks were formed. How did the detective uncover the sequence of events. This is different to relative dating, which only puts geological events in time order.
There are over 30 radiometric methods available. Because of their unique decay rates, different elements are used for dating different age ranges. Disconformities: Relative Dating: Which Came First.adult cam chat live online video web.
