Absolute dating and absolute age are related concepts, but they are not exactly the same.
Absolute Dating refers to the method used to determine the actual age of a rock, fossil, or archaeological artifact in years. This can include techniques such as radiometric dating, which measures the decay of radioactive isotopes, or methods like dendrochronology (tree-ring dating).
Absolute Age, on the other hand, is the specific age of an object or event as determined by absolute dating methods. For example, if a rock is dated using radiometric dating to be 4.5 billion years old, that number represents its absolute age.
In summary, absolute dating is a process or method, while absolute age is the result obtained from that process.
