Mastery Evidence
- Give an example of a quick change to Earth's surface like a volcanic eruption
- Give an example of a slow change to Earth's surface like erosion by wind or water
- Compare quick and slow changes and explain the difference
Assessment Prompt
If you point out a cliff being worn away by waves, can your child explain that this happens slowly, while a volcanic eruption or earthquake changes the land quickly?
