Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages.

What are three ways to date fossils and artifacts?
The Dating GameIts All Relative. One way of dating fossils relies on their relative positions in the ground. Sedimentary Sleuths. When fossils are buried one on top of another, it is easy to arrange them in chronological order. Clocks In Rocks. Radiocarbon Dating. On The Level. Ash Analysis.
How were fossils are dated?
To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.
What are 3 ways to date artifacts?
Very few artifacts recovered from an archeological site can be absolutely dated. Archeologists use several methods to establish absolute chronology including radiocarbon dating, obsidian hydration, thermoluminescence, dendrochronology, historical records, mean ceramic dating, and pipe stem dating.
What are the 4 types of fossil fuels?
Coal, oil, and natural gas are examples of fossil fuels.
