A break in a body of rock along which one block slides relative to another
What is a fault
100
The waves shown on a seismograph?
What are P-Waves, S-Waves, and S-P Waves
100
Measures the ground motion from an earthquake to determine magnitude
What is the Richter Scale
100
Causes rock to move back-and-forth parallel to the wave
What are P-Waves
100
Areas on Earth's surface where no body waves from a particular earthquake can be detected
What are Shadow Zones
200
The strength of or amount of energy released by an earthquake
What is magnitude
200
Records earthquake intensity
What is a seismograph
200
Measures earthquake strength based on the size of the area of the fault that moves, the average distance the fault blocks move, and the rigidity of the rocks in the fault
What is the moment magnitude scale
200
Causes rock to move side-to-side perpendicular to the direction of the wave
What are S-Waves
200
Plates move away form each other to form rifts and mid-ocean ridges
What is a Divergent Boundary
300
A giant ocean wave that forms after a volcanic eruption, submarine earthquake, or landslide
What is a tsunami
300
Tracing of the earthquake that is recorded by a seismograph
What is a seismogram
300
Expresses the intensity, or amount of damage caused by an earthquake
What is the Mercalli Scale
300
Causes the ground to move perpendicular and horizontal to the direction the wave is traveling
What are Love Waves
300
Plates move towards each other and collide to form trenches, mountains, volcanoes, and island arcs
What is a Convergent Boundary
400
The location within Earth along a fault at which the first motion of the earthquake occurs?
What is the Focus
400
The location of an earthquake
What is an epicenter
400
The name of the first seismoscope invented by Chang Heng of China's Han dynasty
What is Houfeng Didong Yi
400
Causes the ground to move with a rolling motion like ocean waves
What are Rayleigh Waves
400
Plates slide past each other while moving in opposite directions in which form faults
What is a Transform Boundary
500
The sudden return of elastically deformed rock to its undeformed shape
What is Elastic Rebound
500
The study of earthquakes and seismic waves
What is seismology
500
Instrument that measures and record motions of the ground, including those of seismic waves generated by earthquakes, nuclear explosions, and other seismic sources
What is a seismometer
500
Seismic waves that travel throught the interior of the Earth
What are Body Waves
500
Cannot pass throught the core because they have large shadow zones
