What is Plate Boundaries?
Within Geography, which covers maps, landforms, weather, climate, population and settlements: understand how our planet and people connect, this topic explains Plate Boundaries. Geography explains how places, people and natural processes connect, so each topic here combines a clear definition with a visual model.
Check that you can explain Plate Boundaries in your own words and give one example from everyday life. If you can do that, you have understood the core idea.
Understanding Plate Boundaries helps you explain patterns on maps and in the news, and make reasoned decisions about places and environments.
Plate Boundaries in detail
There are three main types of plate boundary. At a constructive (divergent) boundary, plates move apart and magma rises to form new crust, as at the Mid-Atlantic Ridge. At a destructive (convergent) boundary, plates move together: a denser oceanic plate is subducted beneath a continental plate, creating deep ocean trenches, volcanoes and earthquakes.
At a collision boundary, two continental plates meet, and neither sinks, so they crumple to form fold mountains, as with the Himalayas. At a conservative boundary, plates slide past each other, with earthquakes but no volcanoes, as along the San Andreas Fault in California.
How the interactive helps you understand Plate Boundaries
Watch the tectonic plates in the interactive. Use any sliders or buttons it offers to change the values and see how the tectonic plates responds.
Before you change anything, predict the result. Then change one value at a time and check whether your prediction was right. This is a quick way to build a correct mental model of Plate Boundaries.
Real-life uses and examples
- Interpret a graph or map that shows Plate Boundaries and say what it suggests.
- Describe a real place where Plate Boundaries can be seen, using a map or photograph.
- Explain how Plate Boundaries affects people, jobs and land use in a region.
Common mistakes to avoid
- Mixing up cause, effect and consequence when you explain Plate Boundaries.
- Writing general statements without a named place or example.
- Learning the definition without testing it. Use the quiz and the interactive to check that you can apply the idea.
