Due to that discovery, Smith was able to recognize the order that the rocks were formed.
Sixteen years after his discovery, he published a geological map of England showing the rocks of different geologic time eras.
Relative dating does not provide actual numerical dates for the rocks.
Much like "continent," "planet" is a word without a precise definition, with history and culture playing as much of a role as geology and astrophysics This is a "living glossary".
This means that the glossary may grow every week as individuals submit new entries.

Relative dating is the science of determining the relative order of past events (i.e., the age of an object in comparison to another), without necessarily determining their absolute age (i.e. In geology, rock or superficial deposits, fossils and lithologies can be used to correlate one stratigraphic column with another.
For a fossil to be a good index fossil, it needs to have lived during one specific time period, be easy to identify and have been abundant and found in many places. If you find ammonites in a rock in the South Island and also in a rock in the North Island, you can say that both rocks are Mesozoic.
