Define relative age dating
In other words, we can say that in relative dating the archaeologist determines that which of the two fossil or the artifacts are older.Contrary to this, absolute dating is the technique, using which the exact age of the artifacts, fossils, or sites are ascertained.These rates of decay are known, so if you can measure the proportion of parent and daughter isotopes in rocks now, you can calculate when the rocks were formed.Because of their unique decay rates, different elements are used for dating different age ranges.Each original isotope, called the parent, gradually decays to form a new isotope, called the daughter.Each isotope is identified with what is called a ‘mass number’.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.
These use radioactive minerals in rocks as geological clocks.
The table below shows characteristics of some common radiometric dating methods.
Geologists choose a dating method that suits the materials available in their rocks. Measuring isotopes is particularly useful for dating igneous and some metamorphic rock, but not sedimentary rock.
In the field of Geology, dating is an important term as it is a technique through which evaluation regarding the age and period about the fossil, remains, the archaeologists do valuables and artifacts.
At first, there were not many methods of dating were available, but now with advancement in the technology, we mainly have two types of techniques to ascertain ages of ancient belongings.
