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.
The methods of relative aging of rocks include faunal succession, cross cutting relationships, and superposition.
The relative age of rocks simply means the age of the rock when such a rock is compared to other rocks. This can be done through faunal succession, cross-cutting relationships, and superposition.
Faunal succession refers to the use of sedimentary rocks for dating through the observations of the plant and animal fossils in them.
Cross-cutting is when the rock layer is cut crossed by a different layer of rock. Superposition implies that the new rock will be on top of the old layer of rocks.
