A landform produced by a collection of
erupted material around a vent.

Volcanic Eruption
Occurs when magma, rock fragments, and gases
break through the earth’s crust onto the surface.

Molten rock within the earth.

Ash
Fragmented volcanic material with particles
that measure less than 2 mm in diameter.
These fragments form when the release of gas shatters magma or
rock surrounding a vent during a volcanic eruption.

Lahar
Mudflow that occurs when rain falls through
clouds of ash or when rivers become choked
with falling volcanic debris.

Caldera: A large, steep-sided, circular or oval
volcanic depression that forms when magma retreats
or erupts from a shallow underground magma
chamber.
With no magma to support the ground above it,
the overlying rock collapses and the caldera is

Lava Dome
A bulbous, steep-sided dome that forms at the
top of a volcano when thick, relatively “cold”
magma emerges form the volcanic opening.
http://volcanoes.usgs.gov/images/pglossary/LavaDome.php
http://www.pbs.org/wgbh/nova/volcano/anat_03.html#fea_top
The lava dome usually grows over time as more magma from within the
chamber continually adds to its shape.

quickly in the cold ocean.

(The most abundant type of lava flow)
Lava that erupts under water piles up to form new crust, or ocean floor.
Pahoehoe
Lava flow from a volcano who’s surface quickly
cools and forms a “skin” that is wrinkled by the
hot lava still flowing beneath it.

Viscosity
The tendency of a liquid to resist
flow.
Shield Volcano
A wide, broadly sloping volcano that
forms from runny lava. It is the
largest of volcanoes.

Composite Volcano
A volcano that forms from alternating
eruptions of viscous lava and broken rock. It
is steep near the summit and flat toward the
base.
Cinder Cone
A small, cone-shaped volcano made of
broken rocks or blobs of hardened lava,
called cinders, that accumulate around the
volcanic vent.
