Based on the "principle of <u>Superposition"</u>, the geology student can say that the layers on top are "younger" than the layers present below.
<u>EXPLANATION:</u>
The principle of superposition is a basic principle in geology which states that in a "sequence of strata", any stratum is "younger" than the one on which it "rests".
Sedimentary rocks are formed by deposition of "one layer on top of another". Therefore, the "layers at the bottom will be older" than the layers of rocks that form above the lower ones.
Scientific investigations produce evidence that helps answer questions and solve problems. If the evidence cannot provide answers or solutions, it may still be useful. It may lead to new questions or problems for investigation. As more knowledge is discovered, science advances.
