100
The movement or trembling of the ground that is caused by a sudden release of energy when rocks along a fault move.
What is an earthquake?
100
These waves travel through the Earth's interior.
What are body waves?
100
Most earthquakes happen here.
What are tectonic plate boundaries?
100
These are the three types of tectonic plate boundaries where earthquakes occur.
What are divergent boundaries, convergent boundaries, and transform boundaries?
100
A fault.
What is a break in the Earth's crust where blocks of crust slide relative to one another?
200
Waves of energy that travel through the Earth away from an earthquake.
What are seismic waves?
200
This wave is the most dangerous.
What is a surface wave?
200
This is the relationship between tectonic plates and earthquakes.
What are tectonic plates move in different directions and different speeds, breaking the Earth's crust into faults, which cause earthquakes?
200
This is where two tectonic plates slide past each other horizontally.
What are transform boundaries?
200
This type of boundary causes normal faults.
What are divergent boundaries?
300
Seismic waves that squeeze and stretch rock.
What are P waves?
300
P and S waves are this type of wave.
What are body waves?
300
Elastic deformation leads to earthquakes; this kind is more like clay being molded.
What is plastic deformation?
300
This is where two tectonic plates push together.
What are convergent boundaries?
300
This may cause subduction, or make mountains.
What are convergent boundaries?
400
The return of deformed rock to it's original shape.
What is elastic rebound?
400
This wave is the fastest.
What is a P wave?
400
This is a break in Earth's crust where blocks of rock slide relative to one another.
What is a fault?
400
These boundaries form strike-slip faults.
What are transform boundaries?
400
The San Andreas fault zone is primarily along a transform boundary, meaning it has this kind of faults.
What are strike-slip faults?
500
Seismic waves that move from side to side.
What are S waves?
500
This wave cannot travel through liquid.
What is a S wave?
500
Places along plate boundaries where large numbers of faults are located.
What is fault zones?
500
This is when two tectonic plates are pulled apart.
What are divergent boundaries?
500
This is how faults are related to earthquakes.
What is the sudden movement of a fault, causing the Earth to move, releasing energy in all directions.
