Chapter 4: Volcanoes and other igneous activity Volcano : Hill or mountain built of lava and/or pyroclastic material erupted from one or several vents. Vent : surface opening of a conduit or pipe; where eruptive material comes to the surface. 3 main types of volcanoes (others exist) Type of volcano largely dependent on tectonic setting and magma composition. Shield volcano Tectonic setting Magma type Characteristics Hazards Lava Gases Bombs Caldera collapse Examples of shield volcanoes: Composite volcano (also known as stratovolcano, composite cone) Tectonic setting Magma type
