What you'll learn
How the Earth's plates move and cause hazards.
Plate boundaries
- Plates move on convection currents.
- Constructive (divergent), destructive (convergent) and conservative (transform) boundaries.
Hazards
- Earthquakes: focus and epicentre; Richter scale.
- Volcanoes: composite (explosive) vs shield (gentle).
- Magma underground becomes lava on the surface.
Exam tips
- Match boundary types to their landforms and hazards.
- Learn a named example.
Common mistakes
- Confusing constructive and destructive boundaries.
- Mixing up focus and epicentre.
