A geology team placed rock layers from two different parts of Earth in order from youngest to oldest. What did the team make?
a fossil record
a geologic record
a geologic column
a topographic map
A hiker in the Beartooth Mountains happens up on a beetle preserved in amber. What has the hiker found?

Which property of fossils allows scientists to determine the relative ages of rock layers?
Fossils show change over time as species evolve because the younger layers will be toward the top.
Fossils form from the remains of living organisms and carbon-14 is useful in carbon absolute dating.
Fossils are only found in sedimentary rock. They are never found in igneous rocks so their ages are based on the layers of sediment in an area.
Fossils can be analyzed to determine their exact ages.
