Relative age dating geology
Principle of cross-cutting relations: The principle is another example of which came first.Instead of using layers, it involves features that cut through the rock, like a fault or a dike.
So, when a valley or canyon cuts through these rock layers, the principle of lateral continuity says that rocks on either side of the canyon were once joined and continuous.
However, it does not cut layers D and E, so those layers are younger than Fault F.
Law of inclusions: This law states that when a rock contains pieces or fragments (also called inclusions) of another rock, these pieces or fragments must be older.
These fossils are found in rocks in chronological order in rock strata with the oldest being on the bottom and the youngest at the top.
This can best be explained by looking at fossils embedded in a rock column.
Principle of fossil succession: This principle is very similar to that of superposition.
