Check understanding
- Correctly classify igneous, sedimentary, and metamorphic rocks and explain in one sentence how each type forms
- Use 'erosion', 'weathering', and 'deposition' correctly as three distinct stages in a sequence
- Explain how fossils form using 'sediment' and 'sedimentary rock' correctly
“Could your child explain the difference between a rock being weathered and being eroded — those are actually two different things?”
