Keeping this in view, what are the principles of relative dating?

Geologists establish the relative ages of rocks mostly through their understanding of stratigraphic succession. The Principle of Original Horizontality states that all rock layers were originally horizontal. The Law of Superposition states that younger strata lie on top of older strata.

Furthermore, what is an example of relative age? The relative age of a rock or fossil is not an exact number or age; it's the comparison of one rock or fossil to another to determine which one is older or younger. Relative dating is done by using a variety of techniques that can be easily used when geologists are working in the field and not in a laboratory.

Similarly, you may ask, which scientist developed many of the basic rules and principles of relative dating?

Nicolas Steno, William Smith, Georges Cuvier, Alexandre Brongniart, and James Hutton developed the basic rules for the science of stratigraphy. Relative dating uses the principles or laws of stratigraphy to order sequences of rock strata.

How do you date relative age?

To determine the relative age of different rocks, geologists start with the assumption that unless something has happened, in a sequence of sedimentary rock layers, the newer rock layers will be on top of older ones. This is called the Rule of Superposition.
