Definition
This is an opening in the Earth's crust where molten rock, ash, and gases erupt from below the surface
Volcano
This is where tectonic plates are moving away from one another.
Constructive plate boundaries (Divergent)
What is the largest type of volcano?
Shield volcano
Mouth of a volcano that surrounds the vent
Crater
What type of volcanic eruption involves the outpouring of basaltic magma that is relatively low in viscosity and in gas content.
Effusive
What volcano is formed in ocean-continent subduction?
Andean-type volcanoes
This is also called composite cone volcano.
Stratovolcano
Considered active if it is currently erupting or has erupted recently, meaning within the past few centuries.
Active volcano
The highest point of the volcano
Summit
What is the process of molten rock (magma) erupting onto the surface of a planet earth?
Volcanism
Large plume of hot mantle material rising from deep within the Earth
Hotspots
This volcano has a steep-walled, basin-shaped depressions formed by the collapse of a volcanic edifice into an empty magma chamber.
Calderas
One that has not erupted in a long time but is still capable of erupting again in the future.
Dormant volcano
Hot fluid or semifluid material below or within the earth's crust from which lava and other igneous rock is formed by cooling.
Magma
This is the molten rocks which erupts from a volcano.
Lava
This is where tectonic plates are moving towards each other. This supports the process of subduction.
Destructive plate boundaries (Convergent)
This type of volcano has circular, mound-shaped protrusion.
Lava dome
No longer capable of erupting and has no potential for future activity
Extinct volcano
Opening in the volcano where the lava comes out.
Vent
What type of volcanic eruption involves magma that is more viscous and has a higher gas content.
Explosive
What volcano is formed in ocean-ocean subduction?
Island-arc volcanoes
This type of volcano are small volcanoes with steep sides and made of pyroclastic fragments
Cinder cone
The passage in the volcano through which magma travels up
Conduit
