What allows molten rock and hot gases to escape from within the earth?
Volcano
Divided into two sections - the liquid outer core and the solid inner core. It is made up of metals rather than rock.

A volcano that has been recorded as active but has not had a recent eruption
Dormant.
holes or cracks that serve as escape vents for underground gases.
Fumaroles
The strength of an earthquake is called its
magnitude
A volcano that has not erupted in recorded history.
Extinct
small fragments of molten rock that solidify almost instantly.
Tephra
as you go deeper into the earth's rocks, what happens to the temperature?
the temperature increases
A volcano characterized by hot clouds and dust.
Plinian
This volcano is formed from large amounts of very fluid lava that builds up gradually
This is created when trapped gases blast through the earth's surface.
Vent
A volcano that has erupted recently
Active
this volcanot is formed by eruptions of mostly Tephra and very little lava
Cinder Cone.
This volcano is formed by alternating layers of tephra and lava
Composite.
