Definition relative dating techniques
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.
This evaluation of the rocks and fossils in the relative dating is known as the biostratigraphy.
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.
No bones about it, fossils are important age markers.
But the most accurate forms of absolute age dating are radiometric methods. Sedimentary rocks in particular are notoriously radioactive-free zones.
Yet, you’ve heard the news: Earth is 4.6 billion years old. That corn cob found in an ancient Native American fire pit is 1,000 years old. Geologic age dating—assigning an age to materials—is an entire discipline of its own.
In a way this field, called geochronology, is some of the purest detective work earth scientists do.
The absolute dating is also sometimes referred as the relative numerical dating as it comes with the exact age of the object.There are two basic approaches: relative age dating, and absolute age dating.Here is an easy-to understand analogy for your students: relative age dating is like saying that your grandfather is older than you.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.

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.
