WebJan 21, 2024 · Relative dating does not offer specific dates, it simply allows to determine if one artifact, fossil, or stratigraphic layer is older than another. Absolute dating methods provide more specific origin dates and time ranges, such as an age range in years. How specific these dates can be will depend on what method is used. WebThis activity will help students to have a better understanding of the basic principles used to determine the age of rocks and fossils. This activity consists of several parts. Objectives of this activity are: 1) To have students determine relative age of a geologically complex area. WebRadiometric dating works because radioactive elements decay at a known rate.
