  1. subduction
    movement of the edge of one tectonic plate under another
    There are more than 1500 active volcanoes on Earth. 95% of these are located at the boundaries of two plates (zones of divergence or of subduction).
  2. plate tectonics
    the movement or study of the movement of Earth's crust
    This volcanic activity is one of the numerous phenomena supporting the theory of Plate Tectonics.
  3. tectonics
    the branch of geology studying the folding and faulting of the earth's crust
    This volcanic activity is one of the numerous phenomena supporting the theory of Plate Tectonics.
  4. ocean floor
    the bottom of a sea or ocean
    They are at the origin of the material that makes up the ocean floor.
  5. oceanic
    relating to or occurring or living in or frequenting the open ocean
    It is estimated that 80% of these volcanoes lie under the oceans, located along the length of the oceanic ridges.
  6. hot spot
    a place of political unrest and potential violence
    The remaining 5% are located  above thermal plumes, in those regions known as “hot spots”.
  7. thermal
    relating to or associated with heat

  8. volcano
    a fissure in the earth's crust through which gases erupt

  9. divergence
    moving away in different direction from a common point
    There are more than 1500 active volcanoes on Earth. 95% of these are located at the boundaries of two plates (zones of divergence or of subduction).
  10. eruption
    the sudden occurrence of a violent discharge
    The gases, ashes and rocks expelled in eruptions are carefully studied in order to better understand the internal composition of the Earth.
  11. volcanic
    relating to eruptions of gas and lava from the earth's crust
    This volcanic activity is one of the numerous phenomena supporting the theory of Plate Tectonics.
  12. ocean
    a large body of water that is part of the hydrosphere
    It is estimated that 80% of these volcanoes lie under the oceans, located along the length of the oceanic ridges.
  13. theory
    a belief that can guide behavior
    This volcanic activity is one of the numerous phenomena supporting the theory of Plate Tectonics.
