Where do earthquakes most often originate?
In the oceans.
At faults.
Near the South Pole.
In Earth's outer core.
The San Andreas Fault that runs through California is an example of:
a normal fault.
a reverse fault.
a strike-slip fault.
What type of plate boundary are volcanoes most often found at?
convergent
divergent
transform
both convergent and divergent
Mapping earthquakes epicenters and volcanic eruptions helps scientists:
determine the location of tectonic plate boundaries.
predict future earthquakes.
predict future volcanic eruptions.
all of the above.
What is an earthquake?
A rupture in Earth's crust.
A large slab of the Earth's lithosphere.
A large rift that develops between diverging tectonic plates.
A disturbance or shaking of Earth's surface.
What is the difference between a focus and epicenter of an earthquake?
There is not difference.
The focus is the location of the earthquake on the Earth's surface and the epicenter is the point within Earth where the earthquake starts.
The focus is the point within Earth where the earthquake starts and the epicenter is the location of the earthquake on the Earth's surface.
The focus is the point within Earth where the earthquake starts and the epicenter has nothing to do with earthquakes.
What is a fault?
A fracture or break in the Earth's crust.
An irregularity in Earth's crust.
A boundary between oceanic crust and continental crust.
A very thin region of Earth's crust.
What is a normal fault?
A fault that occurs where plates push together.
A fault that occurs where plates pull apart.
A fault that occurs where plates slide past each other.
What is a reverse fault?
A fault that occurs where plates push together.
A fault that occurs where plates pull apart.
A fault that occurs where plates slide past each other.
What is a strike-slip fault?
A fault that occurs where plates push together.
A fault that occurs where plates pull apart.
A fault that occurs where plates slide past each other.
Which fault is this?

What is seismology?
The study of rocks.
The study of volcanoes.
The study of weather.
The study of earthquakes.
What type of wave causes the destruction associated with an earthquake?
P-Waves
S-Waves
Surface waves
Longitudinal waves
What is a volcano?
A deep region where two tectonic plates converge.
A type of mountain.
A rupture in Earth's crust through which magma can escape.
A rift in Earth's crust through which water seeps down towards Earth's core.
What is the difference between lava and magma.
Lava is hot and magma is cool.
Magma is inside the Earth and lava flows on the Earth's surface.
Magma flows on the Earth's surface and lava is found inside the Earth.
There is no difference, they are the same thing.
Earthquakes and volcanoes most often occur at:
high elevations.
deep in the ocean.
near the equator.
the boundary of tectonic plates.
