|
The location where two plates meet
What is a boundary?
|
The instrument used for measuring earthquakes
What is a seismograph?
|
The fastest of all seismic waves
What is a P-wave (primary)?
|
The fault along the Pacific Coast

|
The super-continent that once existed
What is Pangea?
|
The TWO locations where an earthquake may occur
What is a boundary or a fault?
|
The record of seismic activity
What is a seismogram?
|
The second seismic wave that is found on a seismogram.
What is a S-wave (secondary)?
|
The fault in the Midwest United States
What is the New Madrid Fault?
|
The idea that the plates underneath Earth's surface move.
What is the theory of plate tectonics?
|
If two plates moves together it is called this
What is a convergent boundary?
|
This scale is used to measure the magnitude of an earthquake.
What is the Richter Scale?
|
The slowest of all seismic waves
What is a surface wave?
|
The fault on the East Coast
What is The Ramapao Fault?
|
This scientist stated that it is not the continents that move but the plates
Who is Henry Hess?
|
If two plates move apart it is called this
What is a divergent boundary?
|
This scale is used to measure the intensity of an earthquake.
What is the Mercalli Scale?
|
The seismic activity that occurs under water
What is a tsunami?
|
This is where earthquakes begin, it is underneath the Earth
What is the focus?
|
One piece of evidence that continental drift occurred
What is fossils of animals OR fossils of plants or rock formations?
|
If two plates that slide past one another it is called this
What is a transform boundary?
|
It is important to locate this, the place on Earth where seismic activity begins.
What is the epicenter?
|
The frequency of seismic activity in the world
What is everyday?
|
This is the type of fault where the crust is extended
What is a normal fault?
