Study Notes
Types of Volcanoes
Shield Volcanoes
- Gently sloping with a broad base and rounded summit
- Formed by the eruption of fluid lava flows
- Examples: Hawaiian Islands, Iceland
Stratovolcanoes (Composite Volcanoes)
- Tall, conical shape with a narrow base and steep slopes
- Formed by a combination of lava flows, ash, and other pyroclastic material
- Examples: Mount St. Helens, Mount Fuji
Cinder Cones
- Small, steep-sided volcanoes with a rounded summit
- Formed by the accumulation of ash and cinder from small-scale eruptions
- Examples: Paricutin Volcano, Sunset Crater
Calderas
- Large depressions formed by massive volcanic eruptions
- Can be filled with water to form a lake
- Examples: Yellowstone Caldera, Crater Lake
Submarine Volcanoes
- Formed on the ocean floor
- Can eventually rise above the water surface to form a new island
- Examples: Loihi Seamount, Kama'ehuakanaloa Seamount
Supervolcanoes
- Extremely large volcanoes capable of producing massive eruptions
- Can affect global climate and cause catastrophic damage
- Examples: Yellowstone Supervolcano, Lake Toba
Types of Volcanoes
Shield Volcanoes
- Characterized by a gently sloping shape with a broad base and rounded summit
- Formed as a result of the eruption of fluid lava flows, which build up a flat or gently sloping shape
- Examples of shield volcanoes include the Hawaiian Islands and Iceland
Stratovolcanoes (Composite Volcanoes)
- Recognizable by their tall, conical shape with a narrow base and steep slopes
- Formed through a combination of lava flows, ash, and other pyroclastic material
- Examples of stratovolcanoes include Mount St. Helens and Mount Fuji
Cinder Cones
- Small, steep-sided volcanoes with a rounded summit, typically formed by the accumulation of ash and cinder from small-scale eruptions
- Cinder cones are often found in clusters or fields, and can be short-lived or long-lived
- Examples of cinder cones include Paricutin Volcano and Sunset Crater
Calderas
- Large depressions formed by massive volcanic eruptions that collapse the ground above
- Can be filled with water to form a lake, and often have a complex geological history
- Examples of calderas include the Yellowstone Caldera and Crater Lake
Submarine Volcanoes
- Formed on the ocean floor, often at the edges of tectonic plates or at hotspots
- Can eventually rise above the water surface to form a new island, such as the Hawaiian Islands
- Examples of submarine volcanoes include Loihi Seamount and Kama'ehuakanaloa Seamount
Supervolcanoes
- Extremely large volcanoes capable of producing massive eruptions that can affect global climate and cause catastrophic damage
- Can have a significant impact on the environment and human populations
- Examples of supervolcanoes include the Yellowstone Supervolcano and Lake Toba
