Distinguish Earth hazards
Distinguish Earth hazards using supplied evidence and a solved model.
About 18 minutes, plus any extended practice
Supplied materials
- All measurements and observations below are supplied classroom examples. They are not data from actual learners or a claim about a particular real site.
- Paper, drawing space or a browser document.
- Reference card A: ground shaking from sudden fault motion. Reference card B: material escapes from a volcano.
- Assessment case 1: Which scientific label fits the specifically described step or feature? Supplied case: Fault motion shakes ground.
- Assessment case 2: Which scientific label fits the specifically described step or feature? Supplied case: Lava and ash emerge.
- Assessment case 3: Which scientific label fits the specifically described step or feature? Supplied case: Slope material moves downhill.
- Assessment case 4: Which scientific label fits the specifically described step or feature? Supplied case: River water spreads over dry land.
- Assessment case 5: Which scientific label fits the specifically described step or feature? Supplied case: Sudden ground shaking.
- Assessment case 6: Which scientific label fits the specifically described step or feature? Supplied case: Hill material slides downward.
Learn the idea
A hazard is a potential source of harm; damage also depends on exposure. Use supplied diagrams. Do not visit a hazard site or test structures in dangerous conditions.
Earthquake means ground shaking from sudden fault motion. Volcanic eruption means material escapes from a volcano. Landslide means rock or soil moves down a slope. Flood means water covers normally dry land.
For earthquake, look for the clue “ground shaking from sudden fault motion.” For volcanic eruption, look for “material escapes from a volcano.” More than one process can happen in a real situation. Answer about the one described in this question.
- Read or listen to the four science words and what each means. Say how the first two differ.
- Choose two of the short cases. Point to the clue that helps you choose a science word for each one. You may draw or say your answer.
- Answer each practice question. Say which clue helped you, then check the explanation.
- Use the extra task to make two examples that show different science words. Draw or say what makes each one fit.
See the method in action
Worked reference-card problem: a card states “ground shaking from sudden fault motion”; a second states “material escapes from a volcano.” The first fits earthquake and the second fits volcanic eruption. The reason is the described function or change, not the order of the cards or a favorite name. If their descriptions exchange places, their category labels exchange too. Keep the supplied descriptions attached to the correct case.

Helpful tips
- Use the feature “ground shaking from sudden fault motion” to justify earthquake; do not sort by the name alone.
- Distinguish volcanic eruption (material escapes from a volcano) from a different process occurring in the same situation.
See the answer and explanation
earthquake
The answer is earthquake. In the notes, it means “ground shaking from sudden fault motion.” A hazard is a potential source of harm; damage also depends on exposure. Use supplied diagrams. Do not visit a hazard site or test structures in dangerous conditions.
Take it further
Create one new case showing earthquake and one showing volcanic eruption. Expected: the first explicitly shows “ground shaking from sudden fault motion”; the second explicitly shows “material escapes from a volcano.” Explain the distinction by drawing, speaking or writing. A label without a matching feature is incomplete.
