Types of Volcanoes
Shield Volcanoes
Broad, gently sloping dome
Formed from runny lava that flows a great distance before it hardens
Examples are Kilauea and Mauna Loa in Hawaii
Cinder Cone Volcanoes
Cone shaped, steep sides with a narrow base
Formed when rock fragments and cinders erupt from a central vent and then pile up around the same vent
Example is Sunset Crater in the U.S.
Composite Volcanoes
Cone shaped with concave sides, classic volcano shape
Has alternating layers of rock/ ash and lava
Formed from alternating violent eruptions and quiet eruptions
Examples are Mt. Rainer, Mt. St. Helens in the U.S. and Mt. Fuji in Japan
