Three plate-boundary patterns
1
Divergent
Plates move apart; new oceanic crust may form at spreading ridges.
2
Convergent
Plates move towards each other; subduction or continental collision may occur.
3
Transform
Plates slide laterally past each other; earthquakes are common along active faults.
The connection Classify the relative motion first, then infer likely landforms and hazards.
Exam trap Not every convergent boundary produces the same volcanic pattern; continental collision differs from oceanic subduction.
Which type of relative motion characterises a transform boundary?
Lateral sliding of adjacent plates past one another.

Plate Tectonics — lesson overview
Plates and motion
Lithospheric plates move relative to one another over a more deformable underlying region. They may include oceanic and continental lithosphere.
Plate motion explains connected patterns of earthquakes, volcanoes, mountain building and ocean-floor development.
A continent is not necessarily a separate tectonic plate; plate and continental boundaries do not coincide everywhere.
Boundary types
Divergent boundaries involve plates moving apart and can form new oceanic lithosphere at spreading centres.
Convergent boundaries involve approach and may produce subduction or continental collision, depending on plate properties.
Transform boundaries involve predominantly lateral relative movement; they need not create or consume lithosphere in the same manner.
Landforms and hazards
Oceanic-continental convergence can form trenches and volcanic arcs where subduction occurs; continental collision contributes to large mountain belts.
Earthquake and volcanic distributions depend on the boundary and setting; not every earthquake is accompanied by a volcanic eruption.
Tectonic explanations distinguish the long-term process from the particular timing and intensity of an individual hazardous event.
