Relative dating of rock strata

This is because the rocks were deposited laterally in continuous flat layers and can be covered with vegetation or eroded in some places.

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.

To understand this better, consider a four-layer cake. It wouldn't be possible for the other layers to be added without the bottom layer first.

This same process applies with each layer to the cake added.

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.

If we put these items in order from oldest to youngest, it would be: A, B, C, Fault F, D, and E.

The reason Fault F is younger than layers A, B, and C is because it cuts the layers.

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.

Sediments can be deposited on an incline, but this doesn't happen very often.
