Study Notes
Volcano Types
- The main factor that differentiates the four main types of volcanoes is their shape and eruption style.
Shield Volcanoes
- Characterized by non-explosive eruptions and gentle slopes.
- Typically have a broad, gently sloping shape.
- Primary characteristic: gently sloping shape and non-explosive eruptions.
- Type of lava: fluid, basaltic lava.
Composite Cone Volcanoes
- Characterized by low-explosivity and mostly lava flows.
- Also called stratovolcanoes.
- Mainly composed of alternating layers of lava, ash, and other pyroclastic material.
- Type of lava: more viscous, andesitic lava.
- Example: Mount St. Helens.
Cinder Cone Volcanoes
- Characterized by small, steep-sided cones and explosive eruptions.
- Typically have a height range of 100-400 meters.
- Characterized by: small, steep-sided cones, and explosive eruptions.
- Type of lava: mafic to intermediate lava.
- Example: Paricutin, a recently developed cinder cone volcano.
Lava Dome Volcanoes
- Characterized by a steep-sided, dome-shaped volcano.
- Distinguishing feature: highly viscous lava that piles up around the volcanic vent.
- Differentiated from cinder cone volcanoes by their shape and eruption style.
Eruptions and Flows
- Pyroclastic flows: composed of hot, fast-moving ash, gas, and rock.
- Shield cone volcanoes: typically experience non-explosive eruptions.
- Cinder cone volcanoes: generally experience explosive eruptions.
- Lava domes: characterized by a slow, effusive eruption style.
Key Differences
- Primary difference between shield cone and composite cone volcanoes: shape and eruption style.
- Primary factor that differentiates cinder cone and shield cone volcanoes: shape and eruption style.
- What distinguishes lava dome volcanoes from cinder cone volcanoes: shape and eruption style.

Description
Explore the characteristics of different types of volcanoes and understand why some are cone-shaped while others are shield-shaped. Learn about the unique features of each type and how they are differentiated based on size, composition, and explosiveness.
