In radiometric dating, the radioactive minerals within the rocks are used to know about the age of the object or the sites.
Geologists often need to know the age of material that they find.
Most commonly, the ancient factors of the rocks or objects are examined using the method called stratigraphy.

As the word relative tells that defining the object with respect to the other object, it will be pertinent to mention here that actual numerical dates of the rocks or sites are not known in this type of dating.
Other than rocks, fossils are the other most important elements in relative dating as many organisms have there remain in the sedimentary rocks.
Geologists use radiocarbon to date such materials as wood and pollen trapped in sediment, which indicates the date of the sediment itself.
The table below shows characteristics of some common radiometric dating methods.
To evaluate the exact age, both the chemical and physical properties of the object are looked keenly.
The main techniques used in absolute dating are carbon dating, annual cycle method, trapped electron method, and the atomic clocks.
These break down over time in a process scientists call radioactive decay.
Each original isotope, called the parent, gradually decays to form a new isotope, called the daughter.
Relative dating is a less advanced technique as compared to absolute dating.
In relative dating, mostly the common sense principles are applied, and it is told that which artifact or object is older than the other one.
These techniques are more complex and advanced regarding technology as compared to the techniques in practice in relative dating.Tags: Adult Dating, affair dating, sex dating
