Answer:

Explanation:

Fossils generally helps in relative dating of rocks.

The Trilobites are considered the oldest in this rock sequence when we apply the principle of superposition of strata.

The principle states that "in an undeformed/undisturbed sequence of rock, the oldest is always at the bottom while the youngest is on top" .

This principle therefore explains why the Trilobites at the base are considered the oldest.

Once this is done, the erosion is slowly (occasionally in a sudden manner) is starting to remove layers of the surface of a particular place, and moving them to another place (which is the process of deposition), thus changing the physical appearance of the place. The erosion is process that has the tendency to flatten the natural features.
