Composite Volcanoes
Constructed from felsic to intermediate rock, often very steep
Explosive eruption due to the extreme viscosity of lava, creating high pressure
Shield Volcanoes
Large, not steep, often located near intraplate hotspots or spreading centers
Non-explosive eruption, lava is fluid and spreads further, creates a less steep structure. Lava has low viscosity
Cinder Cone Volcanoes
Small, cone-shaped, steep, grows rapidly from a single eruption cycle
Usually erupts strongly once, shoots up rocks called pumice up in the air.
