Study Notes
Types of Volcanoes and Their Features
- Shield Volcano: Characterized by a wide, dome-shaped mountain formed by the accumulation of fluid, runny lava.
- Cinder Cone Volcano: Forms from the eruption of tephra, resulting in a steep, cone-shaped mountain comprised mainly of small solidified lava fragments.
- Composite Volcano: Created by alternating layers of fluid lava and tephra, resulting in a steep and symmetrical structure.
Volcanic Structures
- Crater: The bowl-shaped depression located at the summit of a volcano.
- Caldera: A large, bowl-shaped depression that occurs when a magma chamber empties and collapses after an eruption.
Volcano Activity Levels
- Active Volcano: A volcano that has had recent eruptions or shows potential for future eruptions.
- Dormant Volcano: A volcano that is currently inactive but has erupted in the past and may erupt again.
- Extinct Volcano: A volcano that has not erupted in recorded history and is not expected to erupt again.
Types of Eruptions
- Hawaiian Eruption: Involves a significant outpouring of fluid lava, resembling water fountain surges from the volcano's vent.
- Strombolian Eruption: Typically mild and occurs frequently, characterized by sporadic bursts of lava.
- Plinian Eruption: A highly explosive event that ejects hot gas and ash clouds high into the atmosphere, often following a long period of dormancy.
