Archaeological studies of rock art demand a temporal framework in which a particular imagery was produced, as it is the only way to relate decontextualized pictographs and engravings to archaeological cultures. Relative dating does not produce high-resolution chronological frameworks. Relative dating is a science that geologists and archeologists use to determine the chronological sequence of geological events, i.e., their relative ages. It tells whether a geological event is older or younger than another depending on their interrelationships and not actual numerical years, i.e., absolute age.Absolute dating determines the age of an object in calendrical years. There are many such dating methods such as C14 or Carbon 14 method of dating, U238 method of dating, K-Ar or Potassium-Argon method of dating etc. Any of these methods is not applicable for all archaeological findings.

Scientists use two approaches to date rocks and fossils. Relative age dating is used to determine whether one rock layer (or the fossils in it) are older or younger than another base on their relative position: younger rocks are positioned on top of older rocks. Absolute age dating (or, radiometric dating) determines the age of a ... Absolute time is a method for determining the age of a rock or object most often using radiometric isotopes. Atoms are made of three particles, protons, electrons, and neutrons. All three of these particles are important to the study of geology: the number of protons defines a particular element, the number of electrons control how that element ...Description. By knowing the age of the rock that a fossil is found in, geologists can usually tell the age of the fossil. Sometimes they cannot give it an exact date, but they know that it is older or younger than another fossil. Dating a fossil by saying it is older or younger than another fossil is called relative dating. Relative age dating has to do with determining the temporal ordering of events in Earth's past. Geologists employ a handful of simple principles in relative age dating; two of the most important of these are are the principles of superposition and cross-cutting relationships. A third key principle--faunal succession--is reviewed in Section 3. Absolute values are used for determining the magnitude of a number, so they are often used for distance measurements.
