landforms like mountains and coal fields
none of the above
Two plates moving away from each other can create _______ at a boundary under the ocean, creating new crust.
subduction
divergence
sea-floor spreading
tension
A zone of ______ is created when old crust is destroyed and deep ocean trenches are formed.
sea-floor spreading
transform boundary
subduction
mid-ocean ridges
What kind of stress force is found at a transform boundary?
transform
strike-slip
compression
shearing
What type of boundary experiences tension?

When two plates move toward each other, it is called a _____ boundary and it can eventually become a _____ fault.
convergent; reverse
convergent; normal

In the 1900's, scientists mapped mid-ocean ridges using
deep-sea diving
sonar
satellites
submarines
Oceanic crust becomes thicker as it heats up.
True
False
Oceanic crust is usually more dense than continental crust.
True
False
Oceanic crust becomes thicker as it cools.
True
False
What is the reason behind the movement of the lithospheric plates?
continental drift
continuous convergent boundaries
convection currents in the mantle
conduction
A rift valley is formed when two plates move away from each other under water.
True
False
Which of the following normally causes volcanoes?
sea-floor spreading
subduction
convergent boundaries
reverse faults
**DON'T MISS THIS QUESTIONS ON THE TEST. IT IS WORD FOR WORD.** A fold in rock that bends upward into an arch is called a(n)
anticline
syncline
plateau
canyon
The point beneath Earth’s surface where rock breaks under stress and triggers an earthquake is called the epicenter.
True
False
What can you conclude from this image of a seismogram? Select all that apply.
The surface waves were 2-3 times larger than the P waves.
The P waves were recorded first, then the S waves, then the surface waves.
It will help determine when the next earthquake will be.
By measuring the distance between the P and surface waves, they can determine how far away the earthquake's epicenter was.
Which scale relies on human observation for measurement?
moment magnitude
Richter
modified Mercalli
Which scale best measures the magnitude of a local earthquake?
moment magnitude
Richter
modified Mercalli
Which scale rates the total energy released by an earthquake?
moment magnitude
Richter
modified Mercalli
In a normal fault, the hanging wall is "above" the fault line and the footwall is "below" the fault line.
True
False
