question 3(multiple choice worth 3 points)
(03.01 mc)
the table below shows the depths at which an index fossil and three other fossils were found.

which statement is correct?
the index fossil is the oldest fossil.
the index fossil is the youngest fossil.
fossil a is the same age as the index fossil.
fossil b is the same age as the index fossil.

Explanation:

In geology, the principle of superposition states that in undisturbed sedimentary rock layers, the deeper the layer, the older the fossils within it. The index fossil is found at a shallower depth (210 meters) compared to Fossil A (294 meters), Fossil B (385 meters), and Fossil C (375 meters). Sh shallower depth indicates a younger age for the index fossil.

Answer:

The index fossil is the youngest fossil.
