Fossils found in lower rock layers are older than fossils found in upper layers.
Fossils found in lower rock layers are older than fossils found in upper layers.
Fossils found in lower rock layers are older than fossils found in upper layers.
The correct answer is: "Fossils found in lower rock layers are older than fossils found in upper layers."
To determine the location and age of fossils, scientists use a method called relative dating. This method involves studying the layers of rock in which fossils are found and using the principle of superposition. According to this principle, in undisturbed rock layers, the oldest rocks are located at the bottom, and the youngest rocks are located at the top.
Based on this principle, fossils found in lower rock layers are older than fossils found in upper layers. As new sediments accumulate and form new rock layers on top, the older layers get buried deeper, which means the fossils found in those layers are older.
Therefore, the correct choice is that fossils found in lower rock layers are older than fossils found in upper layers.
