  6. Movement of Tectonic Plates (earthquakes)

  7. What are the natural phenomena in anearthquake? Volcanic eruption Crater (lake) Tidalwave

  8. What are the bad effects of anearthquake? Buildings and bridges were collapsed Fire People were killed

  9. What can we do? • Scientists collect data about earthquakes. • Build buildings which can minimize the bad effects of earthquake. • have fire drills.
