Types of Volcanoes
This volcano has gently sloping sides.
What is a shield volcano?
This is a break in the lithosphere where blocks of rock move.
What is a fault?
This is molten rock above ground.
What is lava?
This is the fastest seismic wave.
What is a primary (P) wave?
This is a large wave that results from an earthquake generated in the ocean.
What is a tsunami?
This type of volcano has layers of ash and lava.
What is a composite volcano?
This is .
What is the pipe.
This is molten rock below ground?
What is magma
This instrument measures ground movement caused by seismic waves.
What is a seismometer?
This is an area around the Pacific Ocean where most of Earth's active volcanoes are located.
What is the Ring of Fire?
This type of volcano is a very steep cone shaped hill or mountain.
What is a cinder cone volcano?
This is the number of times greater a magnitude 5 earthquake is than a magnitude 2 earthquake on the Richter scale.
What is 1000 times?
This term describes a liquid's resistance to flow.
What is viscosity?
This type of seismic wave causes the most damage.
What is a surface wave?
This describes a volcano that is quiet but may erupt sometime in the future.
What is dormant?
This is a hole left by the collapse of a volcanic mountain.
What is a caldera?
This is the type of fault that occurs at a convergent boundary.
What is a reverse fault?
This material changes the thickness of the lava.
What is silica?
This seismic wave causes particles in the ground to move in a push-pull motion in the same direction as the wave.
What is a primary (P) wave?
This occurs when thermal energy melts ice and snow at the summit of a volcano.
What is a mud flow?
This is a type of scale that measures earthquake intensity based on damage and effects on people.
What is the Mercalli Scale.
This component affects the explosiveness of volcanoes.
What is dissolved gases?
These waves stop at the inner core because they can not travel through liquids.
What is a secondary (S) wave?
This is an avalanche of hot gas, rock and ash traveling up to 100km/hr.
What is a pyroclastic flow?
