Check understanding
- Explain that rock layers (strata) form over time, with the oldest at the bottom
- Describe how fossils in different layers provide evidence of organisms that lived at different times
- Use patterns in rock formations to explain how a landscape has changed over millions of years
“If your child sees layers of rock in a cliff face, can they explain that the bottom layers are oldest and any fossils tell us what lived there long ago?”
