The three types of volcanoes are shield, cinder cone and composite volcano. Volcanoes are created when heated, melted rock, magma rises to the surface of the Earth. The three types of volcanoes differ in the type of material that actually reaches the surface and the type of eruption that occurs.
Composite volcanoes, also known as stratovolcanoes, are created from repeated explosive eruptions of airborne lava fragments and pure lava. This type of volcano is the largest form.
Shield volcanoes form from non-explosive eruptions of lava that is in a flowing state. This type of volcano is found in the Hawaiian islands.
Cinder cones are a type of volcano formed from lava being forcefully blown up into the air and breaking into fragments.
