State the information that relative dating and radioactive dating provide about fossils
Fossils is an identification event which rotates with Rocks and Minerals every two years. Students identify various fossilized animals and plants, provide details about these organisms such as environment, mode of life, etc. This page primarily covers information applicable to the event in general. This is necessary background information that competitors should know in order to understand the event, but most of the event will focus on fossil identification and details about the fossils. There are several ways that fossils can form, ranging from the organism being replaced by minerals to the organism getting trapped in amber.
Radiometric Dating: Definition, How Does it Work, Uses & Examples
Geology: Relative Dating Vs Radioactive Dating
Radiometric dating , radioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbon , in which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay. Together with stratigraphic principles , radiometric dating methods are used in geochronology to establish the geologic time scale. By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change. Radiometric dating is also used to date archaeological materials, including ancient artifacts.

The age of fossils can be determined using stratigraphy, biostratigraphy, and radiocarbon dating. Paleontology seeks to map out how life evolved across geologic time. A substantial hurdle is the difficulty of working out fossil ages. There are several different methods for estimating the ages of fossils, including:.
