- Unit 2.2 · Plate Boundaries
- Unit 2.3 · Earthquakes & Volcanoes
- Unit 2.4 · Evidence for Continental Drift
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 · Plate Boundaries — explain and transfer
Use the unit’s worked cases and changed independent application.
Your task
Study the illustrated worked case, attempt practice and the changed case, then revise the opening explanation and complete the exit response.
- Explain the worked diagram in your own words.
- Attempt varied practice and the independent changed case.
- Check evidence/calculations using the rubric.
- Return to the first model and explain a revision before the exit response.
Hint and response guidance
Read the stated evidence and diagram captions; separate quantities, reference frames and assumptions before deciding.
The gap closes at 6−2 = 4 cm/year. Relative convergence is established, but plate types, trench geometry, earthquake depths and geological evidence are needed to distinguish subduction from other convergent settings.
- 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 · Earthquakes & Volcanoes — observe and build
Illustrative evidence case. Two towns report different shaking from one event. A station records an early P arrival and a later S arrival.
Your task
Read the chapter context and the unit language notes. Make a first model, study the core explanation and Parts 1–2, and attempt their visual and reasoning checks.
- Read the assigned context and note two observations.
- Draw a first explanation with one uncertain feature.
- Study Parts 1–2 and trace each diagram label.
- Attempt checks before consulting guidance and record one revision.
Hint and response guidance
Read the stated evidence and diagram captions; separate quantities, reference frames and assumptions before deciding.
The subsurface start is the focus or hypocenter; the town’s projected point is the epicenter. The distinction concerns position, not two separate earthquakes. 105−60 = 45 s. It constrains distance under the model but not a unique direction; additional station information is needed.
- 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 3 · Earthquakes & Volcanoes — connect mechanisms
Rock begins melting when its temperature, pressure and composition meet suitable conditions. Rising mantle can cross its melting conditions as pressure decreases; this is decompression melting. Water released in a subduction setting can lower the temperature needed for some mantle material to melt. Hot magma can also transfer energy into other rock. Each mechanism changes a different part of the condition comparison, and usually only some material melts. Magma is melt containing possible crystals and gases beneath the surface; lava is erupted molten material at the surface.
Your task
Study Parts 3–4 and any source records. Complete the whole-unit application with a labeled diagram, calculations and a limitation.
- Define each new quantity and its unit.
- Compare the diagrams and stated evidence.
- Attempt the whole-unit application without copying guidance.
- Check intermediate reasoning and annotate a correction.
Hint and response guidance
Read the stated evidence and diagram captions; separate quantities, reference frames and assumptions before deciding.
Reduced pressure or added water can permit partial melting without the same required temperature rise. The setting and evidence identify which mechanism is appropriate. The changes are consistent with a changing volcanic system but have alternative causes, uncertainties and no exact-time calibration in this graph. Combine gas, deformation and seismic evidence with expert monitoring.
- 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 4 · Earthquakes & Volcanoes — explain and transfer
Use the unit’s worked cases and changed independent application.
Your task
Study the illustrated worked case, attempt practice and the changed case, then revise the opening explanation and complete the exit response.
- Explain the worked diagram in your own words.
- Attempt varied practice and the independent changed case.
- Check evidence/calculations using the rubric.
- Return to the first model and explain a revision before the exit response.
Hint and response guidance
Read the stated evidence and diagram captions; separate quantities, reference frames and assumptions before deciding.
The S–P gap is 36 s. Distance inference needs the appropriate travel-time model; direction requires other stations. Damage also depends on local intensity, depth, ground and structures, so one gap or surface location is insufficient.
- 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 · Evidence for Continental Drift — observe and build
Illustrative evidence case. Separated regions contain matching fossil groups in comparable-age strata. A ridge has young crust near its center and older crust farther away.
Your task
Read the chapter context and the unit language notes. Make a first model, study the core explanation and Parts 1–2, and attempt their visual and reasoning checks.
- Read the assigned context and note two observations.
- Draw a first explanation with one uncertain feature.
- Study Parts 1–2 and trace each diagram label.
- Attempt checks before consulting guidance and record one revision.
Hint and response guidance
Read the stated evidence and diagram captions; separate quantities, reference frames and assumptions before deciding.
Matching dated rock sequences, mountain belts, fossil distributions with suitable ages/ecology and past-climate indicators can test the reconstruction. Modern motion measurements supply a further, different test. No. Their identification, age ranges and ecology must be checked. Very different ages can reflect separate occurrences rather than the proposed simultaneous connected habitat.
- 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?
