Chapter 2 · Earth’s Interior & Plate Tectonics
Assigned readings
This chapter follows the question: What evidence explains a changing solid Earth?
This week’s goals
- Explain mechanisms with labeled figures and relevant records.
- Distinguish measured observations, illustrative models and conditional projections.
- Apply ideas independently and revise after feedback.
Read Mountains move, but several mechanisms matter before starting this chapter. Use the linked unit explanations and source records during the assigned sessions.
Five flexible sessions normally about 45 minutes. Assessment slots explicitly combine or extend sessions to the existing paper’s full time. Slow down and use consolidation sessions for reteaching when an explanation is not secure.
Session 1 · Test a Seafloor-Spreading Model — plan and model
Does ocean-crust age change with distance from a spreading ridge?
Your task
Define the question, boundary, variables and predictions; follow the stated safety/material route or use the supplied-record route.
- Read the question and distinguish supplied versus collected data.
- Use the method and safety notes for the selected route.
- Complete the current investigation stage with units and labeled evidence.
- Record one interpretation and one limitation to revisit.
Hint and response guidance
Read the stated evidence and diagram captions; separate quantities, reference frames and assumptions before deciding.
Age increases symmetrically away from the ridge. On one side, 120 km / 6 Ma = 20 km/Ma = 2 cm/year; opposite sides separate at 4 cm/year in this ideal model. The pattern supports new crust forming at the ridge. Magnetic-stripe symmetry and independent motion measurements would add evidence. Average ages cannot establish the speed at every instant. A complete notebook also specifies the boundary, measurement units and matched conditions. Describe a mechanism connecting the pattern to the claim, then state a limitation and an additional comparison. Supplied illustrative outcomes are not a claim about your collected results; differences must be interpreted rather than corrected to match the example.
- Use the stated evidence and units accurately.
- Explain a mechanism or evidence relationship.
- Show a labeled model, graph or intermediate calculation.
- State a limitation and a useful revision/test.
Session 2 · Test a Seafloor-Spreading Model — records and comparison
Does ocean-crust age change with distance from a spreading ridge?
Your task
Collect or analyze the repeated records; retain units, controls and differences without inventing measurements.
- Read the question and distinguish supplied versus collected data.
- Use the method and safety notes for the selected route.
- Complete the current investigation stage with units and labeled evidence.
- Record one interpretation and one limitation to revisit.

Session 3 · Test a Seafloor-Spreading Model — explain and revise
Does ocean-crust age change with distance from a spreading ridge?
Your task
Graph the data, explain the mechanism, assess uncertainty, revise the model and submit a complete notebook.
- Read the question and distinguish supplied versus collected data.
- Use the method and safety notes for the selected route.
- Complete the current investigation stage with units and labeled evidence.
- Record one interpretation and one limitation to revisit.

Session 4 · Earth’s Interior & Plate Tectonics — chapter review
What evidence explains a changing solid Earth?
Your task
Use the chapter review and compare the units’ diagrams. Include the new visual-transfer question for every unit and explain corrections.
- Retrieve key ideas without notes.
- Attempt the review before opening answers.
- Explain one link across units.
- Correct a misconception using evidence.
Hint and response guidance
Read the stated evidence and diagram captions; separate quantities, reference frames and assumptions before deciding.
Use the chapter review solutions and per-unit transfer rubrics; accept an equivalent supported explanation.
- Use the stated evidence and units accurately.
- Explain a mechanism or evidence relationship.
- Show a labeled model, graph or intermediate calculation.
- State a limitation and a useful revision/test.
Session 5 · Earth’s Interior & Plate Tectonics — chapter quiz
Check independent understanding of the full chapter.
Your task
Take the chapter quiz independently, then use objective checking and parent/teacher marking guidance for written responses.
- Prepare the stated permitted materials.
- Complete the quiz independently.
- Mark written reasoning with the supplied rubric.
- Select a specific reteaching target.
Hint and response guidance
Read the stated evidence and diagram captions; separate quantities, reference frames and assumptions before deciding.
Use question-specific criteria after the attempt; written explanations require human judgment.
- Use the stated evidence and units accurately.
- Explain a mechanism or evidence relationship.
- Show a labeled model, graph or intermediate calculation.
- State a limitation and a useful revision/test.
Submit this week
- First and revised models with explained changes.
- Assigned independent practice or assessment attempt and corrections.
- Investigation records/graphs with units and limitations when scheduled.
Parent / teacher weekly conference
Assess explanations against the task criteria, discuss a real attempt before opening guidance, and adapt pacing to the learner. These home-study sessions do not certify NYSED laboratory eligibility.
- Can the learner explain each relevant diagram label?
- Are quantities, units and assumptions correct?
- Can the learner solve a changed case without copying?
