A. they are both used to determine the relative ages of rocks and fossils.
The correct statement that describes the relative age of a fossil that has formed inside a layer of rock is B. the fossil is older than the layer of rock it was formed in.
To understand why this is the case, we need to have knowledge of the principles of relative dating, which help us determine the relative ages of rocks and fossils. The two main principles involved in this process are the Law of Superposition and the Principle of Cross-Cutting Relationships.
The Law of Superposition states that in a sequence of undisturbed sedimentary rock layers, the oldest rocks are on the bottom, and the youngest rocks are on the top. This means that if a layer of rock contains a fossil, it must have formed after the surrounding rock layers were already in place.
The Principle of Cross-Cutting Relationships tells us that if a geological feature, such as a fault or igneous intrusion, cuts through a layer of rock, it is younger than the rock it cuts through. In the case of a fossil formed inside a layer of rock, the layer itself is considered older than the fossil because the fossil is contained within it.
Therefore, in the context of a fossil formed inside a layer of rock, the fossil is older than the layer of rock it was formed in.
