Volcanoes can be hundreds of miles across and many
tens of thousands of feet high, have low
slopes and consist almost entirely of
frozen lavas
EFFUSIVE ERUPTIONS
they almost always have large craters at
their summits
the individual islands of Hawaii are simply
large shield volcanoes

4. Mauna Loa, Hawaii

5. Composite
Volcanoestypically measure tens of miles across and ten
thousand or more feet in height
Effusive and explosive eruptions
they have moderately steep sides and
sometimes have small craters in their summits
they are called composite because they consist
of layers of solid lava flows mixed with
cinders (volcanic ash)

6. Mt. Nyiragongo, Democratic
Republic of Congo

7. Cinder
Cone
Volcanoes

across andup to about a thousand feet high
Explosive eruptions
