• uniformitarianism.

• original horizontality.

• superposition.

• cross-cutting relationships.

In an undisturbed rock sequence, the youngest rock layer is located

• at the bottom of the sequence.

• at the top of the sequence.

• below the sedimentary rock layer.

• below the unconformity.

What are particles eroded from a layer of rock that become incorporated in an overlying rock layer?

• fossils

• unconformities

• sills

• inclusions

An eroded surface that overlies rock layers that are tilted is a(n)

• nonconformity.

• disconformity.

• angular unconformity.

• cross-cutting relationship.

The relative age of a rock layer that contains inclusions is

• older than the source of the inclusions.

• older than the layer below it.

• younger than the source of the inclusions.

• the same as the intrusion that cuts across it.
