This set goes deeper on tectonics from physical geography. Each question supplies its own diagram or data, and your answer must use it.
The four lessons build in order, and the practice set mixes them.
What does this set cover?
- Distinguishing convergent, divergent and transform boundaries in diagrams reads arrow directions.
- Linking a plate process to an identified landform says which boundary made a trench, ridge or fold mountain.
- Explaining earthquake patterns from supplied location data reads depth and distance figures.
- Separating a classroom hazard model from a real-time safety forecast draws the line between learning and warning.
One short example: one arrow decides three answers
An original diagram shows two plates with arrows pointing towards each other. The left plate is thin and dense, and the right plate is thick and light. The thin plate dips below the thick one.
Arrows towards each other mean a convergent boundary. The dense plate sinks, which forms a deep trench and a line of volcanoes on the thick plate. Earthquakes occur along the sinking plate.
| Clue on the diagram | Conclusion |
|---|---|
| Arrows pointing towards each other | Convergent boundary |
| One plate dipping below the other | Subduction |
| Trench beside a volcano line | Landforms of an ocean-continent boundary |
How do the parts connect?
The arrows give the boundary type. The boundary type predicts the landform, and the same movement explains the pattern of earthquakes. The model lesson then marks the limit of what any of this can say about tomorrow.
Who should start where?
- Confuse the three boundary types: start with reading arrows.
- Know the landforms but not their causes: start with linking process to landform.
- Struggle with tables of depths and distances: start with earthquake patterns.
- Asked about safety and prediction: start with the model versus forecast lesson.
