Lesson 3 Types Of Volcanoes

  1. 1. Types of Volcano Starter- Dominoes.
  2. 2. Active volcano – liable to erupt.
  3. 3. Dormant (sleeping) volcano – a volcano which has not erupted for many years
  4. 4. Extinct volcano – a volcano which has not erupted for many thousands or millions of years
  5. 5. Types of Volcano <ul><li>Composite Volcano </li></ul><ul><li>Shield Volcano </li></ul>
  6. 6. Shield Volcano <ul><li>Occur at Constructive Plate Boundaries. </li></ul><ul><li>Runny Lava that flows along way from the main vent. </li></ul><ul><li>Gives the volcano gentle sides. </li></ul><ul><li>Shield volcanoes almost never erupt violently due to the lava running free (no rocks). </li></ul>
  7. 7. Composite Volcanoes. <ul><li>Occur at destructive plate boundaries. </li></ul><ul><li>Viscous (thick lava) </li></ul><ul><li>The lava cannot flow far from the vent. </li></ul><ul><li>Makes the volcano steep sided. </li></ul><ul><li>Violent eruptions due to rapidly hardening rock which blocks vents and allows the pressure to build. </li></ul>
  8. 8. So why do people live near them? <ul><li>Watch the following movie about why people live near volcanoes. </li></ul><ul><li>Now we have seen the video make a list of the advantages of living near a volcano. </li></ul>
