Shield Volcanoes
  • Quiet & non-explosive;
  • Great masses of lava quietly ooze out from an opening in the earth\'s crust;
  • Liquidy lava;
  • Gently sloping cone.
  • The largest volcanoes on earth

cinder cone volcanoes
Cinder Cone Volcanoes
  • Explosive volcanoes;
  • Volcanic bombs, cinders, and ash are hurled out of an erupting volcano;
  • Most have a bowl-shaped crater at the summit
  • Some of the tallest volcanoes

lava dome volcanoes
Lava Dome Volcanoes
  • Volcanic or lava domes are formed by relatively small, bulbous masses of lava that are very viscous (sticky & gooey)
  • A steep-sided mass
  • Its surface is often rough and blocky as a result of fragmentation of the cooler, outer crust during growth of the dome
