Rock layers and Earth's history
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
Teaching approaches
Gakuva’s recommended starting approach is selected. You can still compare every option.
1 approach
If your child 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?
