If your child picked up a piece of marble on a school trip, could they explain how it was originally limestone, what changed it into marble, and how long that process took?

Check understanding
- Describes how each rock type (igneous, sedimentary, metamorphic) is formed
- Gives an example of each rock type and its formation (e.g. granite, limestone, marble)
- Traces a rock sample through possible transitions in the rock cycle
- Explains what geological time means and why rock cycle changes are slow
