**Best for:** Students facing a dense chapter who want to see how the ideas connect before memorizing them, and teachers making a study aid for a reading.

## Prompt

```
Turn this textbook chapter (or section) into a concept map I can study from, in plain text.

Chapter text:
{{chapter_text}}

Build it like this:
1. Core idea: one sentence the whole chapter supports.
2. Concepts: the 8-12 key concepts, each with a one-line definition in your own words.
3. Links: list the relationships as "Concept A --[verb phrase]--> Concept B" (e.g. "causes", "is a type of", "is measured by", "limits"). Every concept must connect to at least one other. Include at least 2 cross-links between distant branches; those are what exams test.
4. Tree view: an indented outline showing the hierarchy from the core idea down.
5. Gaps: anything the chapter mentions but doesn't explain, and any link you inferred rather than read (mark inferred links with *).

Use only what's in the text. If the text is too short for 8 concepts, use fewer and say so.
```

## Variables

- `{{chapter_text}}` — The chapter or section, pasted as text (one section at a time works best). (e.g. Earth's outer shell, the lithosphere, is broken into large pieces called tectonic plates...)

## Example input

```
chapter_text: Earth's outer shell, the lithosphere, is broken into large pieces called tectonic plates. The lithosphere includes the crust and the rigid upper part of the mantle. The plates rest on the asthenosphere, a hotter, partly molten layer of the mantle that can flow slowly. Heat from Earth's interior drives convection currents in the mantle, which help move the plates a few centimeters per year.

Where plates meet, we find plate boundaries. At divergent boundaries, plates move apart; magma rises to fill the gap and forms new crust, as at the Mid-Atlantic Ridge. At convergent boundaries, plates collide. When an oceanic plate meets a continental plate, the denser oceanic plate sinks beneath it in a process called subduction, producing deep ocean trenches and volcanoes, as in the Andes. When two continental plates collide, neither sinks easily, so the crust crumples upward into mountain ranges like the Himalayas. At transform boundaries, plates slide past each other horizontally; stress builds up and is released as earthquakes, as along the San Andreas Fault.

Evidence for plate movement includes matching fossils on continents now separated by oceans, the fit of coastlines such as South America and Africa, and the pattern of earthquakes and volcanoes, which cluster along plate boundaries. The idea of moving plates grew out of Alfred Wegener's earlier theory of continental drift, which lacked a mechanism to explain the motion.

## Output

*Produced by Claude · Opus 5.5.*

```
**1. Core idea**
Earth's rigid outer shell is split into plates that move slowly over a flowing mantle layer, and what happens where plates meet explains new crust, earthquakes, volcanoes and mountains.

**2. Concepts**
1. **Lithosphere:** Earth's rigid outer shell, made of the crust and the upper mantle.
2. **Tectonic plates:** the large pieces the lithosphere is broken into.
3. **Asthenosphere:** a hot, partly molten mantle layer that flows slowly; the plates rest on it.
4. **Mantle convection:** heat-driven currents in the mantle that help move the plates.
5. **Divergent boundary:** where plates move apart and rising magma forms new crust.
6. **Convergent boundary:** where plates collide.
7. **Subduction:** a denser oceanic plate sinking beneath a continental plate.
8. **Continental collision:** two continental plates colliding, with crust crumpling into mountains.
9. **Transform boundary:** where plates slide past each other horizontally.
10. **Earthquakes:** the sudden release of built-up stress.
11. **Evidence for plate movement:** fossils, coastline fit, and the pattern of earthquakes and volcanoes.
12. **Continental drift:** Wegener's earlier theory that continents move, which had no mechanism.

**3. Links**
- Lithosphere --[is broken into]--> Tectonic plates
- Tectonic plates --[rest on]--> Asthenosphere
- Mantle convection --[helps move]--> Tectonic plates
- Tectonic plates --[meet at]--> Divergent, Convergent and Transform boundaries
- Divergent boundary --[creates new crust for]--> Lithosphere *(cross-link)*
- Convergent boundary --[oceanic vs. continental produces]--> Subduction
- Convergent boundary --[continental vs. continental produces]--> Continental collision
- Subduction --[forms]--> ocean trenches and volcanoes (Andes)
- Continental collision --[builds]--> mountain ranges (Himalayas)
- Transform boundary --[releases stress as]--> Earthquakes (San Andreas)
- Earthquakes --[cluster along boundaries, providing]--> Evidence for plate movement *(cross-link)*
- Continental drift --[grew into the idea of]--> Tectonic plates
- Mantle convection --[supplies the mechanism missing from]--> Continental drift (inferred *, cross-link)

**4. Tree view**
- Plate tectonics
  - Structure
    - Lithosphere (crust + upper mantle) → tectonic plates
    - Asthenosphere (flows slowly)
  - Driving force: mantle convection
  - Plate boundaries
    - Divergent → new crust (Mid-Atlantic Ridge)
    - Convergent
      - Oceanic-continental → subduction → trenches, volcanoes (Andes)
      - Continental-continental → collision → mountains (Himalayas)
    - Transform → earthquakes (San Andreas)
  - Evidence: fossils, coastline fit, earthquake and volcano pattern
  - History: Wegener's continental drift (no mechanism)

**5. Gaps**
- Why oceanic plates are denser isn't explained.
- Oceanic-oceanic collisions aren't covered.
- "Help move" suggests other forces, but none are named.
- Earthquakes are only linked to transform boundaries, although the text says they cluster along plate boundaries generally.
- \* The convection-to-continental-drift link is inferred: the text says drift lacked a mechanism and describes convection, but never connects the two.
```

## Why it works

**Labeled links** ("--[verb phrase]-->") are what make it a concept map rather than a list: you have to know *how* two ideas relate, not just that they do. Requiring **every concept to connect** and **at least 2 cross-links between distant branches** targets the connections exams test and summaries miss.

The **tree view** gives you the hierarchy at a glance, and the **gaps section, with inferred links marked \***, separates what the chapter says from what the model assumed. That matters when you're studying for a test that's marked against the textbook.

## When not to use it

Plain text can't show a map spatially; if you're a visual learner, redraw it by hand or in a diagram tool, which is also better practice. Long chapters give crowded, shallow maps, so do one section at a time. And a map built for you is less memorable than one you build; try your own first and use this to check it.
