Diving away plates
Note:
  • Plate movements cause not only earthquakes but also volcanoes
  • Rule: the deeper you go into the earth, the higher the temperature becomes. A submerged plate partially melts. It creates magma that rises and causes volcanic eruptions.
  • Near Japan, the two oceanic plates dip below the Eurasian continental plate.
