100
Large,steep sided volcano that results from explosive eruptions of andesite and rhyolitic s lavas
What is COMPOSITE VOLCANO
100
a scale, ranging from 1 to 10, for indicating the intensity of anearthquake.
What is RICHTER SCALE
100
a vent in the earth's crust through which lava, steam, ashes,etc., are expelled, either continuously or at irregular intervals.
What is VOLCANO
100
a series of vibrations induced in the earth's crust by the abruptrupture and rebound of rocks in which elastic strain has beenslowly accumulating.
What is EARTHQUAKES
100
The area of earthquake and volcano activity around the Ring of Fire
What is PACIFIC
200
Small,steep-sided volcano that erupts gas-rich, basaltic lava.
What is CINDER CONE VOLCANO
200
A measure of damage done by an earthquake
What is MERCALLI SCALE
200
Tiny particles of pulverized volcanic rock and glass
What is VOLCANIC ASH
200
Based partly on the earthquake history of an area
What is EARTHQUAKE RISK
200
Boundary where one tectonic plate descends into the mantle and partially melts
What is CONVERGENT
300
Large volcano with gentle slope of basaltic lava
What is SHIELD VOLCANO
300
S-wave causes particles in the ground to move side to side and up and down at right angles
What is SECONDARY WAVE
300
Molten rock that erupts onto Earth’s surface
What is LAVA
300
The point where an earthquake begins
What is FOCUS
300
Magma with high silica content
What is ANDESITE
400
P-wave fastest-moving type of seismic wave-causes push-pull motion
What is PRIMARY WAVE
400
Volcano that is not associated with a plate boundary
What is HOT SPOT
400
Boundary where two tectonic plate separate
What is DIVERGENT
500
Molten rock below Earth’s surface
What is MAGMA
500
Is a depression formed when a volcano’s summit collapse or is blown away by an explosive eruption
What is CALDERA
