What is the seismic wave that can pass through solid, liquid and gas and is the fastest seismic wave and the first to arrive at a seismograph station?
P Wave
100
What is a Hot Spot?
A stationary magma intrusion that periodically erupts as a volcano on the surface as a tectonic plate continues to move but does not move with the tectonic plate
100
What is a Fold?
A bend of rock layers produced from compression forces
100
What is a Normal fault?
A fault where the Footwall moves up and the Hanging wall moves down?
200
When ocean to ocean plates come together, they form a?
Subduction Zone
200
What is a seismic wave that can only travel through solid material and arrives second at a seismograph station ?
S wave
200
How many seismograph stations are required to locate the epicenter of an earthquake?
THREE
200
What is an Anticline?
An upward fold of rock layers
200
What is a reverse fault?
A fault where the Footwall drops down and the Hanging wall moves up
300
What is the boundary called when two plates pull apart?
A divergent boundary
300
P Waves and S Waves
What are the two Body Waves called?
300
the earthquakes origin usually inside the Earth.
What is the focus?
300
What is a Syncline?
A downward fold
300
What is a fault called where the surface layers of rock slip or slide past each other?
A Strike-Slip fault
400
What is the name of the transform boundary located in California?
The San Andreas Fault
400
What is the machine called that records the earthquake?
Seismograph
400
What is the epicenter located?
Directly on the Earth's surface above the earthquake's origin
400
What is a Monocline?
A fold where one side is bent down or upwards. Looks like a step.
400
What is a Fault Block Mountain?
Produced when large blocks of the Earth's crust drop down relative to other blocks
500
What type of feature is formed when an ocean plate dives under a continental plate?
A trench
500
What scale is used that measures an earthquake's magnitude?
The Richter Scale
500
Which seismic wave causes the most damage?
The Surface Wave or L Wave
500
What is Stress?
The amount of force per unit area. A constant steady pressure will fold the rock but too much will cause it to snap and fault, thus producing an earthquake.
