Scientific definition of relative dating
We don't need to know what year any of these movies came out to place them in order of relative age.
Nemo is the oldest, followed by Twilight, Hunger Games, and the Avengers Again, we have not stated anything about the actual age of these movies, we've just put them in order relative to one another.
The first step is determining whether similar beds in separated outcrops can actually be traced laterally until they are seen to be part of the same original layer.Correlation is, as mentioned earlier, the technique of piecing together the informational content of separated outcrops.When information derived from two outcrops is integrated, the time interval they represent is probably greater than that of each alone.Presumably if all the world’s outcrops were integrated, sediments representing all of geologic time would be available for examination.
This optimistic hope, however, must be tempered by the realization that much of the Precambrian record—older than 541 million years—is missing.The same thing can be done with geologic features in a rock outcrop.
