      Lesson details

      Learning outcome

      I can describe where earthquakes occur and explain how they happen.

      Key learning points

      1. Earthquakes are sudden, violent movements of the ground caused by tectonic plate movement.
      2. Earthquakes usually happen on or near plate boundaries.
      3. At a plate boundary two plates are locked together, yet moving in different directions.
      4. When rock fractures at a plate boundary this causes an earthquake.
      5. Small earthquakes can also occur far from plate boundaries.

      Keywords

      • Tectonic plates - the huge pieces that Earth’s surface is broken into

      • Plate boundary - where two plates meet

      • Fault lines - fractures in Earth’s surface

      • Focus point - the point deep underground where the tectonic plates first break

      Common misconception

      Plate boundaries are clean cuts through the ground which separate two plates.

      There is not one fault but many, which make up a plate boundary and the rock is locked together across the two plates.

      Teacher tip

      Get up-to-date details of earthquakes in the UK and globally using the British Geological Survey and US Geological Survey websites.

      4 Questions

      Q1.
      What are tectonic plates?

      Thin clouds in Earth’s atmosphere
      Correct answer: Huge pieces of Earth’s crust that move slowly
      Deep cracks filled with lava

      Which of the following is true about plate boundaries?

      They are neat, straight cuts in the ground
      They never change
      They can be seen clearly from space
      Correct answer: They are complex zones where plates may grind past each other
