Rock layers and Earth's history
Science · Earth's Systems · representational
Interpret cross-section diagrams of the Earth's interior, geological strata, and rock cycle; read and label layers (crust, mantle, outer core, inner core); understand that deeper layers in sedimentary sequences are older
What mastery looks like
- Label the four layers of the Earth on a cross-section diagram using the correct terms
- Interpret a diagram of sedimentary rock layers and identify which layer was deposited first
- Read a rock cycle diagram and trace the pathway of a rock from igneous to sedimentary to metamorphic
Check your understanding
If Rock layers and Earth's history sees a cut-away diagram of the Earth, can they point to and name the different layers — and if shown stacked rock layers, can they say which layer formed first?
