100
Molten rock stored beneath earth's surface.
What is magma?
200
an instrament that measures and records ground motion and can be used to determine the distance seismic waves travel.
What is a seismometer?
200
What type of scale increases by 1 unit and represents ten times the amout of ground motion recorded on a seismogram.
What is the Richter Magnitude Scale?
200
How does the amount of silica in lave affect the flow of magma?
The magma will flow more slowly the greater the amount of silica that is within the lava.
200
Which type of wave travels the deepest into the center of Earth?
What is P-waves?
200
Tiny particles of pulverized volcanic rock and gas.
What is volcanic ash?
300
A graphical illustration of seismic waves.
What is a seismogram?
300
It evaluates the damage that results from shaking, and measures earthquake intensity based on descriptions of the earthquake's effects on people and structures.

300
A small, step-sided volcano that erupts gas-rich, basaltic lava.
What is a Cinder Cone volcano?
400
A location inside Earth where seismic waves originate and rocks first move along a fault and from which seismic waves originate.
What is Focus?
400
It measures the total amount of energy released by the Earthquake.

A large steep-sided volcano that results from explosive eruptions of andestic and rhyolitic lavas along convergent boundaries.
What is a Composite volcano?
500
Scientist that studies earthquakes
What is a seismologist?
500
It measures magnitude, and uses the amount of ground motion at a given distance from an earthquake to determine magnitude.
What is the Richter Magnitude Scale?
500
Giva as many detalis as possible about silica- rich magma?
-Forms at convergent boudaries where one plate is forced under another.
-Produces explosive eruptions.
-Is thick and traps gas, causing pressure to build up.
500
What are some differences between P and S-waves?
P-waves can travel through solids and liquids.
S-waves can only travel through solids.
P-waves are faster.
S-waves are slower.
500
A large volcano with gentle slopes of basaltic lava, common along divergent boundaries and oceanic hotspots.
