What are the three types of volcanoes?
- Shield Volcanoes
- Composite Volcanoes
- Cinder Cone Volcanoes
- All of the above (correct)
Describe Shield Volcanoes.
Describe Shield Volcanoes.
Shield volcanoes are volcanic cones formed from quiet or non-explosive eruptions. They have broad bases and gently sloping sides, covering a wide area, and are constructed by hot mafic (thin runny) lava flows.
Describe Cinder Cone Volcanoes.
Describe Cinder Cone Volcanoes.
Cinder cone volcanoes are a common type of volcano that forms in clusters, typically characterized by steep slopes and made primarily of pyroclastic material, formed by explosive eruptions.
Describe Composite Volcanoes.

Study Notes
Types of Volcanoes
- Three main types of volcanoes: Shield, Composite, and Cinder Cone.
Shield Volcanoes
- Characterized by broad bases and gently sloping sides.
- Formed mainly from quiet, non-explosive eruptions.
- Consist of hot mafic (thin, runny) lava that spreads out, hardens, and builds the cone.
- Cover large areas, resulting in wide, gentle slopes.
- Examples include Kilauea and Mauna Loa in Hawaii.
Cinder Cone Volcanoes
- Common and found in clusters, often appearing in groups.
- Formed from explosive eruptions that eject pyroclastic material.
- Feature very steep slopes due to the accumulation of debris.
- Comprised primarily of small fragments of lava and volcanic ash.
- Notable examples are Paricutin in Mexico and Cerro Negro in Nicaragua.
Composite Volcanoes
- Large volcanic mountains known for their size and structure.
- Composed of alternating layers of hardened lava flows and pyroclastic material.
- Eruptions can be both quiet, where lava flows out, and explosive, releasing pyroclastic materials.
- Also referred to as stratovolcanoes due to their layered appearance.
- Famous examples include Mt. Fuji in Japan and Mt. Tambora in Indonesia.
Hypotheses about Volcanoes
-
Shield Volcanoes:
- Shape: Broad base, gently sloping sides.
- Type of eruption: Quiet or non-explosive.
- Examples: Kilauea, Mauna Loa, Mount Kae.
-
Cinder Cone Volcanoes:
- Shape: Very steep slopes.
- Type of eruption: Explosive.
- Examples: Paricutin, Cerro Negro.
-
Composite Volcanoes:
- Shape: Large volcanic mountains with layer formations.
- Type of eruption: Both explosive and non-explosive eruptions with lava flows.
- Examples: Mt. Fuji, Mt. Tambora.
