Parts of a volcano
What three kinds of land forms are created by the eruptions of volcanoes?
Cinder cone, Shield, and Composite
Molten rock beneath the earth's surface.
What are active volcanoes?
Active volcanoes are the volcanoes that erupt constantly.
Magma chambers are reservoirs from which volcanic materials erupt.
What is a cinder cone?
Type of volcanic land form is made up of small rock particles, or cinders.
What is a hot spot?
A region of volcanic activity in the middle of a tectonic plate.
What are dormant volcanoes?
These volcanoes have become inactive, but people are not certain that they will not erupt again.
What is a vent?
Openings through which volcanic materials erupt are called vents.
What is a shield volcano?
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 volcanic island arc?
A long curved chain of volcanic islands.
What are Extinct Volcanoes?
Volcanoes that have not erupted in recorded history are considered to be extinct volcanoes.
What are craters?
Forceful explosions that blow out the tops of mountains to form craters.
What is a composite volcano?
This type of volcanic land form is made up of layers of lava flows alternating with layers of ash, cinders, and rocks.
What is Ring of Fire and where is it located?
A zone of frequent earthquakes and volcanic eruptions.
How do the types of volcanic eruptions differ?
Active: erupt constantly Intermittent: erupt at fairly frequent intervals Dormant: have become inactive but might erupt in future Extinct: have not erupted within recorded history
