focus
T or F: Animals can sense and earthquake
False

How do plates cause an earthquake?
They scrape together
a violent eruption that sends lava, ash, cinders, and gas into the air
volcanic eruption
T or F - In areas where earthquakes occur, buildings are built with laminated rubber to prevent major damage.
True
How do you measure magnitude of an earthquake
the Richter Scale
I used to erupt, but haven't for quite awhile and I probably won't erupt again
dormant
Occurs when rocks move apart forming a gap
Normal fault
Magma that gets to the earths surface is called
lava
buildup and release of energy when two surface plates move or shift
earthquake
beginning point of an earthquake
focus
This volcano is expected to erupt again within the next 5 years. It has a bowl-like crater and only one vent
active cinder cone volcano
Occurs when rocks move horizontally (side to side) past each other
Strike-Slip fault
Not a volcano but I blow steam and hot water into the air
geyser
vibrations that are sent out from the focus
seismic waves
There were earthquakes in the Bible! Which book records a story of an earthquake?
Numbers
this is a large volcano that is layered showing different types of lava flow but it is currently inactive
dormant composite volcano
Occurs when rocks push together forcing a section of rock upward
Thrust or reverse fault
besides a volcano, heat escapes the earth via a
hot spring, geyser, or mud pot
Which waves are the most destructive?
surface waves
Love waves and Rayleigh waves.
This detects the time and movement of earth during a quake
seismograph
this is a large gradually sloping volcano with mild eruptions and continuous flow of lava
active shield volcano
