Types of Volcanoes

A _________ is a steep conical hill of loose

pyroclastic fragments, such as volcanic clinkers,

volcanic ash, or scoria that has been built around a

volcanic vent.

• cinder cone

• composite

• shield

• lava dome

________ volcanoes are tall,

symmetrically shaped, with steep

sides, sometimes rising 10,000

feet high. They are built of

alternating layers of lava flows,

volcanic ash, and cinders.

• lava dome

• shield

• composite

• cinder cone

____________ is a type of volcano

named for its low profile, resembling a

warrior's shield lying on the ground. It is

formed by the eruption of highly fluid

lava, which travels farther and forms

thinner flows than the more viscous lava

erupted from a stratovolcano.

• shield

• composite

• submarine volcano

• super volcano

a____ ____ is a circular,

mound-shaped protrusion resulting from

the slow extrusion of viscous lava from a

volcano. Dome-building eruptions are

common, particularly in convergent plate

boundary settings. Around 6% of eruptions

on Earth are lava dome forming.

A supervolcano is a volcano that has

had an eruption with a Volcanic

Explosivity Index of 8, the largest

recorded value on the index. This

means the volume of deposits for such

an eruption is greater than 1,000 cubic

kilometers.

• lava dome

• super volcano

• shield

• cinder cone

____________ are underwater vents

or fissures in the Earth's surface from which

magma can erupt. Many submarine

volcanoes are located near areas of tectonic

plate formation, known as mid-ocean ridges.

The volcanoes at mid-ocean ridges alone are

estimated to account for 75% of the magma

output on Earth.

A ________, also known as a

glaciovolcano, is a volcanic form

produced by subglacial eruptions or

eruptions beneath the surface of a

glacier or ice sheet which is then

melted into a lake by the rising lava.
