The point where an earthquake starts, and the point on the surface where p & s waves hit the Earth's surface.
What is the focus and the epicenter?
100
Primary or compression waves.
What are two other names for p waves?
100
This one is tall and steep, usually forming at convergent boundaries.
What is a strato or composite volcano?
100
This causes earthquakes and volcanoes.
What is plate movement?
200
They are the names of the hypothesis and the theory.
What is continental drift and plate tectonics?
200
These two words mean the earthquake recording machine and the recording machine paper.
What are seismographs and seismograms?
200
This wave moves side to side like a snake on the ground.
What is a secondary wave?
200
This type of volcano has a gradual slope, typical of Hawaiian volcanoes.
What is a shield volcano?
200
This the name of the volcanic hazard of ash and dust during an eruption.
What is pyroclastic material or flow?
300
San Andreas Fault, Himalaya Mountains, and Iceland.
What are famous features of transform, convergent, and divergent boundaries?
300
This is how an earthquake's intensity is measured.
What is the Mercalli scale?
300
These are the two types of surface waves.
What are Love and Rayleigh waves?
300
An example of these two types of volcanoes are Red Hill near Fossil Falls, and Long Valley near Mammoth, CA.
What are cinder cone and caldera volcanoes?
300
This type of seismic surface wave would cause a house to shift up and down.
What is a Love wave?
400
This is the name of the study of iron banded formations.
What is paleogeomagnetism?
400
These faults have not had a major earthquake in a long time, and is predicted to have one in the near future.
What is seismic gap?
400
S waves cannot go through the liquid outer core, this is why this area exists.
What is a shadow zone?
400
This type of magma causes the most violent eruptions.
What is felsic magma?
400
This type of fault probably causes the most damage.
What is an oblique fault?
500
Two words that mean continents join together, and continents split apart.
What is accretion and rifting?
500
This is how the exact location of an epicenter is located.
What is three seismic recording stations overlap their p & s wave arrival times/distances?
500
This is the cause of Love and Rayleigh waves.
What are p & s waves reaching the surface?
500
There are two reasons that volcanoes have formed in Iceland.
What is a hot spot and divergent boundary?
500
This country is located on a convergent boundary, the Ring of Fire, and has a history of extensive earthquakes, volcanic eruptions, and in 2010, a very destructive tsunami.
