Flashcards
Cinder Cone Volcanoes
Cinder Cone Volcanoes
Cone-shaped mountains with a narrow base that erupt thick pieces of lava.
Composite Volcanoes
Composite Volcanoes
Tall mountains formed from layers of hardened lava and ash, known for violent eruptions.
Shield Volcanoes
Shield Volcanoes
Volcanoes with a large base and gently sloping sides, formed by thin lava flows.
Study Notes
- Volcanoes come in different shapes and sizes, and exhibit different types of eruptions and lava.
Cinder Cone Volcanoes
- Cone-shaped mountains characterized by a narrow base.
- Eruptions send thick pieces of lava high into the air.
- Lava falls back down around the vent in large chunks.
- This repeated process creates a steep, cone-shaped mountain with a bowl-shaped crater for a vent.
- Found in many states in the western part of the United States, such as New Mexico and Arizona.
- Mt. Capulin in New Mexico is a well-known example.
Composite Volcanoes
- Often the image people have in mind when they think of a volcanic eruption.
- Tall mountains created from repeated layers of hardened lava and ashes.
- Violent eruption may occur when large amounts of thick lava build up inside.
- Lava escapes through multiple vents and cracks on the volcano’s surface.
- Mount St. Helens and Mount Pinatubo are examples.
Shield Volcanoes
- Have a large base and sloping sides.
- Shortest type of volcano, resembling the shape of an ancient Greek warrior’s shield.
- Form over time by numerous eruptions of thin lava, that can easily travel down the side of the volcano.
- Lava may travel a great distance before cooling.
- Found in Hawaii and Alaska, and other places throughout the world.
