Force acting on a rock.
A break in the rock or crust.
Where can you find a lot of faults?
Stress that pushes together.
Stress that pulls apart.
Stress that pushes the rocks/ plates past each other in different directions.
Which type of stress forms a reverse fault.
Which type of stress forms a strike-slip fault?
Which type of stress forms a normal fault?
The shaking and trembling that results from the movement of the rock under the crust.
Causes an Earthquake
Forces of plate movement.
Where do Earthquakes begin?
The area beneath the crust that's under stress.
The point on the Earth's surface directly above the focus of an earthquake.
What forms during an Earthquake?
Seismic waves that that compress and expand the ground.
Seismic waves that vibrate from side to side.
Waves that move slower, but are more harsh.
A scale of earthquake intensity
A scale that rates an earthquake's magnitude based on the size of its seismic waves
Moment magnitude scale
A scale that rates earthquakes by estimating the total energy released by an earthquake
Liquid and solid
What can P waves go through?
What can S waves go through?
How to find the epicenter
draw circle, find the radius of each circle, that is the distance from that seismograph to the epicenter.
