Where do most volcanoes occur?
Most volcanoes, like most earthquakes, occur along the boundaries between shifting tectonic plates.

What are active volcanoes?
Active volcanoes are the volcanoes that erupt constantly.
200
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?

What is a geyser?
A hot spring with narrow spaces in its plumbing which erupts periodically and forcibly ejects hot water.

Why does the rock in the mantle melt?
As the tectonic plate moves under another (subduction zone), the rock in the mantle melts and becomes magma.

What are dormant volcanoes?
These volcanoes have become inactive, but people are not certain that they will not erupt again.
300
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?

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.

This volcano is a composite volcano located in the phillipines. Its last eruption was in 1991 which leads to its classification of active.

Craters are bowl-shaped depressions. Forceful explosions may blow out the tops of mountains to form craters.
What are craters?
400
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?
400
An open plumbing system in which the superheated water is able to rise freely to the surface.
What is a hot spring?
400
Earthquakes, slope of the mountain (bulge), gases and temperature changes from satellite imagery
What is ways scientists predict volcanoes?

What are Extinct Volcanoes?
Volcanoes that have not erupted in recorded history are considered to be extinct volcanoes.

subduction occurs when two plates collide. the denser; heavier, palte slides under the other plate and becomes part of the mantle.
Define Subduction Zone. Where is it located?

Which type of volcanic landform is the most destructive? Name a volcanic landform that was developed this way.
Composite volcano.
Mt. St. Helens is a composite volcano.
500
A zone of frequent earthquakes and volcanic eruptions that encircles the Pacific Basin.
what is Ring of Fire and where is it located?

How do hot spots form new land? Name a landform created by hot spots.
Hot spots erupt and release magma. As magma comes out it becomes lava and hardens into landforms.
Hawaiian islands are created by hot spots.
