Types of volcanoes

Types of Volcanoes

Volcanoes are classified under

4 categories:

Shield Volcanoes

Cinder Cone

Composite or Stratovolcanoes

Lava Domes


Shield volcanoes
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

Composite or stratovolcanoes
Composite orStratovolcanoes

  • Also called: STRATOVOLCANOES

  • Alternating layers of lava and cinders on earth;

  • Consists of many separate vents

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
