What is a seismograph?
What is a machine that records movements of earth's plates or crust.
100
What kind of eruption is likely to occur in a volcano having magma that is low in silica? Explain
What is quiet eruptions because there will be less pressure built up

What is the main hazard in a quiet eruption?
What is lava flows
200
Molten material that reaches the surface is called...
What is lava

What is shield
200
What kinds of stresses cause vibrations in Earth that result in an earthquake?
What is compression, tension, and shearing

What are three faults and how does the hanging wall move for each?
What is reverse (hanging wall moves up), normal (hanging wall moves down), and strike-slip faults (hanging wall slides past).
300
What are 3 types of seismic waves?
What is primary (fastest), secondary (occurs second), and surface (slowest).

What do we call a huge hole left by a collapse of a volcanic mountain?
What is caldera
300
What causes magma to erupt to the surface?

400
What should you do if you are caught in an earthquake?
What is stop, drop, and hold or cover

Describe how a seismograph works
What is records vibrations of the earth. It has a weight attached to the frame by a spring or wire, a pen connected to the weight rests on a drum, which rotates as the pen writes movements from seismic waves during an earthquake
