Relative dating is the science of determining the relative order of past events i. Whereas, relative dating arranges them in the geological order of their formation. Potassium is common in rocks and minerals, allowing many samples of geochronological or archeological interest to be dated. Most commonly, the ancient factors of the rocks or objects are examined using the method called stratigraphy. It is based on the concept that heated objects absorb light, and emit electrons.

The rate of decay of these elements helps determine their age, and in turn the age of the rocks. Famous Chemists and Their Contributions. The main techniques used in absolute dating are carbon dating, annual cycle method, trapped electron method, and the atomic clocks. This is a radiometric technique since it is based on radioactive decay.
In other words, we can say that the age in relative dating is ascertained by witnessing the layers of deposition or the rocks. Dendrochronology can date the time at which tree rings were formed, in many types of wood, to the exact calendar year.
