What can you infer about the rocks that formed at the bottom of this formation?

• The rocks are older than those above them because the principle of superposition states that the oldest rocks are on the bottom

• The rocks are younger than those above them because the principle of superposition states that the youngest rocks are on the bottom

• The rocks are older than those above them because the principle of original horizontality states that the oldest rocks are on the bottom

• The rocks are younger than those above them because the principle of original horizontality states that the youngest rocks are on the bottom
