The correct statement about fossils location and age is:
- Fossils found in lower rock layers are older than fossils found in upper layers.
The correct statement is: "Fossils found in lower rock layers are older than fossils found in upper layers."
To determine the age of fossils and their location within rock layers, scientists use a principle known as the Law of Superposition. According to this principle, in undisturbed rock layers, the oldest rocks are found at the bottom, while the youngest are found at the top.
As new layers of sediment are deposited over time, older layers are buried deeper, and new fossils accumulate in the more recently formed layers. This means that if a fossil is found in a lower rock layer, it is generally older than fossils found in upper layers.
Therefore, the statement that "Fossils found in lower rock layers are older than fossils found in upper layers" is correct because it aligns with the principle of superposition.
