Vocabulary:
Lava Plateaus: layers of lava form high plateaus
Caldera: large hole at the top of a volcano formed when the roof of a volcano’s magma chamber collapses

Shield
Cinder cone
Composite or
Strato
(made of more
than one or
layers)
Large, sloping mountain that
forms from thin, flowing
lava that cools
From cinders that erupt from
the volcano and land close to
the vent to form the
mountain
Lava flows that alternate
with cinder and ash
explosions- the alternating
layers form a cone-shaped
mountain
