Mastery Evidence

  • 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 [child] explain the difference between a rock being weathered and being eroded — those are actually two different things?”

Prerequisites0
