Presentation transcript:

Shield Volcano Built of layers of lava by repeated non- explosive eruptions Lava is runny (low viscosity) Has gentle sloping sides Ex: Mauna Kea-tallest mtn. on earth

Cinder-Cone Volcano Built of layers of pyroclastic material by explosive eruptions Has steep slopes Small volcanoes and erupt for short periods of time Occurs in clusters (groups of volcanoes) Erodes quickly Ex: Paricutin, Mexico

Composite Volcano Built of layers of pyroclastic material (explosive eruptions) & lava (nonexplosive eruptions) Has broad base and steep slopes a.k.a. stratovolcano Most common type of volcano Ex: Mt. Fuji, Mt. St. Helens, Mt. Hood
