What do the law of superposition and the law of inclusion have in common? (1 point) 1. Both laws are about matching fossils in different areas. 2. Both laws give the exact ages of rocks. 3. Both laws describe the relative ages of rocks. 4. Both laws are about the ages of intruding rocks.

Both the laws that is, law of superposition and law of inclusion are used for determining the relative ages of rocks. Hence, option (3) is correct.

The given problem utilizes the concepts of the law of superposition and law of inclusion to find out the common matches between them.

As per the law of superposition, "each rock layer is older than the one above it". This means that the layers of rock that are settled at most bottom are much older than the upper layers of rock. So law of superposition determines the relative age of the rock or fossil.

While the law of inclusion states that, "within the sequence of layers of sedimentary rock, the most oldest layer is at the base and each layers are younger with the ascending order in sequence.

Thus, we can conclude that both the laws that is, law of superposition and law of inclusion are used for determining the relative ages of rocks. Hence, option (3) is correct.
