Types of rocks
Use vocabulary for Earth's geological processes and rock types — igneous, sedimentary, metamorphic, erosion, weathering, deposition, fossil, sediment, strata, permeable, impermeable — and apply these when explaining how rocks form and how landscapes change over time
Suggested ages 9–11
Learning journey
Your child is learning how Earth's surface changes over time — studying how wind, water, and ice shape our landscape through weathering and erosion, and interpreting maps to understand geological patterns.
Evidence of 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
Assessment prompt
Could Types of rocks explain the difference between a rock being weathered and being eroded — those are actually two different things?
