PROBLEM: Paragraph- Sent 1: Fossils can be used to match up rock layers.
Sent 2: As organisms change over time, they look different.
Sent 3: Older fossils will look different than younger fossils.
Sent 4: Some organisms only survived for a short time before going extinct.
Sent 5: Knowing what organisms looked like at certain times also helps date rock layers.
Sent 6: Some fossils are better than others for this use.
Sent 7: The fossils that are very distinct at certain times of Earths history are called index fossils.
Sent 8: Index fossils are commonly used to match rock layers.
Sent 9: You can see how this works in Figure 2.30.
Sent 10: If two rock layers have the same index fossils, then they're probably about the same age.
Question: How can extinction help to date rock layers?.

SOLUTION: Some animals only existed during certain time periods before becoming extinct. It helps to date that layer of rock where these animal fossils are present.
