One method or relative dating
The relative dating is less advanced technique as compared to the 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.For example, archaeologists might date materials based upon relative depth of burial in a site.The archaeologists record and analyze the changes in types and styles of human-made items from different levels according to the principle explained below.
The absolute dating is the technique to ascertain the exact numerical age of the artifacts, rocks or even sites, with using the methods like carbon dating and other.
In radiometric dating, the radioactive minerals within the rocks are used to know about the age of the object or the sites.
Prior to the availability of radiocarbon dates (and when there is no material suitable for a radiocarbon date) scientists used a system of relative 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, the absolute dating is the technique, using which the exact age of the artifacts, fossils, or sites are ascertained.
The resulting sequence from the bottom-most sediments would be oldest-to- young-to- older.
