Answer:

index fossils, intrusions, and cross-cutting relationships

Explanation:

The relative ages of rocks involves using relationships within a sequence to infer the likely age of a rock unit.

There several principles that can be used to infer the relative ages of rocks.

Using materials such as index fossils, intrusions, and cross-cutting relationships, we can place strata into their ages.
Fossils are the remains of organisms preserved in rocks.
Intrusions are bodies that cuts through a rock
Cross - cutting relationships are features like fractures that are cuts a rock.
