  1. Types of volcanoes

  2. There are three types • Shield Volcano • Cinder Cone • Composite Volcano

  3. Shield Volcano • Shaped like a long, flat dome • Built up by many eruptions of lava • Sides are layers of lava • Lava flows out gently and for great distances • Hawaii is made up of this type of volcano. • One of Earth’s most active volcanoes

  4. Cinder Cone • Steep sides • Cone-shaped hill • Formed from eruption of cinders and other rock fragments • Very explosive eruptions • Magma is thick and resists flowing • Eruptions have a lot of cinder and ash.

  5. Composite Volcano • Cone-shaped • Steep near top, flatter towards bottom • Built of layers of lava and rock fragments • Produce a lot of lava and ash • These produce very explosive eruptions because gas is trapped inside the volcanoes. This is due to lava from previous eruptions plugging the holes in a volcano’s side.
