Lesson details

Key learning points

  1. There is a pattern in the global distribution of earthquakes.
  2. There is a pattern in the global distribution of volcanoes.
  3. The global distribution of earthquakes and volcanoes coincides with plate margins.

Keywords

  • Epicentre - the point on Earth's surface that is directly above where an earthquake happens underground

  • Magnitude - a measure of the energy released by an earthquake

  • Margin - the boundary where tectonic plates meet

  • Hotspot - an area in Earth's mantle where unusually hot magma rises toward the surface, creating volcanic activity

Common misconception

That both volcanoes and earthquakes occur at all types of plate margin.

While earthquakes are produced by tectonic movements at all plate margins, volcanoes are not found at conservative plate margins.

This lesson uses AQA terminology for plate margins; for Edexcel B plate boundaries are used instead of plate margins, destructive margins are convergent boundaries and constructive margins are divergent boundaries.
