4 types of absolute dating
The relative dating is the technique to ascertain the age of the artifacts, rocks or even sites while comparing one from the other.
In relative dating the exact age of the object is not known; the only thing which made clear using this is that which of the two artifacts is older.
Since radioactive elements decay at a constant rate, by measuring the volume of the parent isotope versus the volume of the daughter isotope, an estimate of the age of a rock or other material can be determined.
Contrary to this, the absolute dating is the technique, using which the exact age of the artifacts, fossils, or sites are ascertained.
Students not only want to know how old a fossil is, but they want to know how that age was determined.
Some very straightforward principles are used to determine the age of fossils.
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 the relative dating as many organisms have there remain in the sedimentary rocks.
