Parts of a Volcano
Lava is magma that flows out onto Earth's surface.
What is lava?
The three types of volcanoes.
What are Cindercone, Shield, and Composite?
Molten rock beneath the earth's surface.
What is Magma?
What are Plate Boundaries?
Magma chambers are reservoirs from which volcanic materials erupt.
What are magma chambers?
This type of volcanic landform is made up of small rock particles, or cinders. It is characterized by a small cone with steep sides.
What is a cinder cone volcano?
Several mountains that lie together.
What is a mountain range?
What happens to a plate as it subducts under another?
What is return to the mantle?
Openings through which volcanic materials erupt are called vents. They are located near the peak of the mountain.
What is a vent?
This type of volcano is made up of layers of lava rocks. it's not as steep as cinder cone volcano and is created slowly that's why it has gentle and broad sides.
What is a shield volcano?
A region of volcanic activity in the middle of a tectonic plate.
What is a hot spot?
Why does magma rise?
magma, the melted mantle, rises because it is filled with gas and is less dense than the solid rock around it.
Bowl-shaped depressions. Forceful explosions may blow out the tops of mountains to form craters.
What are craters?
This type of volcanic landform is made up of layers of lava flows alternating with layers of ash, cinders, and rocks. it is a combination of cinder cone and shield volcanoes.
What is a composite volcano?
A line of volcanic island is referred to as...
What is a volcanic island chain?
This occurs when two plates collide and the denser; heavier, plate slides under the other plate and becomes part of the mantle.
What is subduction?
The most destructive type of volcano.
What is a Composite volcano?
A zone of frequent earthquakes and volcanic eruptions that encircles the Pacific Basin.
What is the Ring of Fire?
