C) The fossil is older than the layer of rock it was formed in.
can you explain
Yes, of course!
The relative age of a fossil refers to its age compared to other fossils or rock layers. When a fossil is formed inside a layer of rock, it is engulfed or buried by the rock formation. In this case, the fossil would have been present before the layer of rock was formed around it.
So, the correct answer is C) The fossil is older than the layer of rock it was formed in.

Use this sentence: A fault cuts across several layers of rock.
Which conclusion can be made?
A)The fault is older than the layers of rock based on the law of crosscutting.
B)The fault is younger than the layers of rock based on the law of crosscutting.
C)The fault is younger than the layers of rock based on the law of inclusion.
D)The fault is older than the layers of rock based on the law of inclusion.

B)The fault is younger than the layers of rock based on the law of crosscutting.
C)The fault is younger than the layers of rock based on the law of inclusion.
D)The fault is older than the layers of rock based on the law of inclusion.
The correct answer would be B) The fault is younger than the layers of rock based on the law of crosscutting.
The law of crosscutting relationships states that any feature that cuts across or disrupts another feature is younger than the feature it cuts across. In this case, the fault is cutting across several layers of rock, indicating that the fault must have formed after the layers of rock were already in place. Therefore, the fault is younger than the layers of rock.

explain it
The law of superposition and the law of inclusion both describe the relative ages of rocks.
The law of superposition states that in an undisturbed sequence of rock layers, the oldest rocks are located at the bottom, while the youngest rocks are located at the top. This principle helps geologists understand the relative order of events in Earth's history.
The law of inclusion states that any rock fragment or fossil found within another rock layer must be older than the rock layer it is found in. This is because the inclusion must have formed first before being incorporated or deposited within the subsequent rock layer.
Both of these laws help scientists establish the relative ages of rocks in a given area by considering the order in which they were formed or deposited. They do not provide the exact ages of rocks, but rather offer insights into the relative sequence of events in the geological history of an area.
