Models
100
Seismic waves lose energy to this.
What is friction?
100
Seismic waves do this as they go deeper into the mantle.
What is speed up?
100
A smaller tremor that follows a major earthquake.
What is an aftershock?
100
Materials a P wave can pass through.
What are solids, liquids, and gases?
100
This model is an idea or thought model (in your mind).
What is a conceptual model?
200
Seismic waves lose energy to this.
What is spreading their energy over large areas of earth?
200
After speeding up, seismic waves also do this as they go deeper into the mantle.
What is refract?
200
The point inside the earth where slippage of rocks occur (where the energy is released)
What is the focus?
200
Materials an S wave can pass through.
What are solids?
200
This is a (3 D) structure made to represent something else.
What is a physical model?
300
Scientific name for primary wave.
What is compressional wave?
300
The earth's layers in order from the surface in.
What is crust, mantle, outer core, inner core?
300
A measure of the energy released by an earthquake.
What is magnitude?
300
The number of times more energy released from a 7 to an 8 on the Richter Scale.
What is 31 times?
300
A line drawn on a map with one side divided and one side undivided, for measuring distance.
What is a graphic scale?
400
Scientific name for secondary wave.
What is shear wave?
400
Two things that happen to a seismic wave when it enters a material of different density.
What is changes speed and refracts?
400
Scale that tells us the energy of an earthquake.
What is the Richter Scale?
400
The number of times vibrations increase from a 5 to a 6 on the Richter Scale.
What is 10 times?
400
One centimeter equals one kilometer (on a map).
What is a verbal scale?
500
Direction a shear wave's energy moves relative to the wave direction.
What is perpendicular?
500
Direction a compressional wave's energy moves relative to the wave direction.
What is parallel?
500
Instrument that records seismic waves.
What is a seismograph?
500
The seismic wave that "lags behind" and arrives second at a seismograph.
What is a shear wave (S wave or secondary wave)?
500
1:62500 (inches) on a map.
What is a ratio scale?
