B. Faunal Succession

C. Cross cutting relationships

D. Superposition

Explanation : The relative age of the rocks depicts the age of the rock when compared to other rocks.

Faunal succession is a method that uses sedimentary rocks for dating by observing the plant and animal fossils in them.

Cross cutting depicts that the rock layer cut crossed by a different layer of rock must be older than the rock that cut through it.

Superposition means that the new rock lies on the top of the old layer of rocks.

Faunal succession

cross-cutting relationships

superposition

Explanation:

Relative dating helps determine geological events by observing rocks.

Faunal succession is a method that uses sedimentary rocks for dating by observing the plant and animal fossils in them.

Cross-cutting relationships show that the layer that cuts across other layers are younger than the layers that they cut through.

Superposition states that younger layers are formed on top of the older layers. So if you are looking at the layers beneath the Earth, the ones that are in the bottom are older and as time pass younger layers form on top of them.
