WebThis lesson is designed to help students understand the concepts of radioactive dating to help determine the approximate age of fossils and rocks. After this lesson students will have an understanding of how materials undergo radioactive decay and that the rate of decay allows scientists to predict the approximate age of the specimen. WebJan 27, 2024 · One way that helps scientists place fossils into the correct era on the geologic time scale is by using radiometric dating.

Many people assume that rocks are dated at “millions of years” based on radiocarbon (carbon-14) dating. But that’s not the case. The reason is simple. Carbon-14 can yield dates of only “thousands of years” before it all breaks down. The most well-known of all the radiometric dating methods is radiocarbon dating. WebThe two techniques that paleontologists use to determine the age of fossils are relative dating and radioactive dating. How are eras and periods related? Eras are subdivided into periods which range in length from tens of millions of years to less than two million years. tsb ireland bank login
