Earthquakes
Types of Stress/Faults
100
The outermost layer of Earth
What is the crust
100
The theory that the tectonic plates have moved over time.
What is Continental Drift
100
What type of boundary involves two plates moving away from each other?
What is divergent boundary
100
What type of plate boundary do earthquakes typically occur?
What is transform
100
This type of stress was modeled using the silly putty... two rocks were being pulled apart, causing thinning in the middle
What is tension
200
The layer of the Earth where there are convection currents.
What is the mantle
200
This is the layer that is divided into tectonic plates.
What is the crust
200
Two plates collide with each other at what type of boundary?
What is convergent boundary
200
What type of waves are released when an earthquake occurs?
What is seismic waves
200
This type of stress forms mountains.
What is compression
300
The Earth is made up of this many layers.
What is four.
300
The mantle is constantly slowly moving in different directions due to what?
What is convection currents
300
At a convergent boundary between two continental plates, what land form is most likely to occur?
What is mountains
300
What other destructive force can occur because of an earthquake?
What is tsunami
300
What type of stress occurs when two plates are sliding past each other?
What is shearing
400
This layer is liquid, and composed of iron and nickel.
What is the outer core.
400
What is land feature is formed at a divergent plate boundary between two oceanic plates?
What is mid-ocean ridge
400
Describe what happens at a transform boundary.
What is two plates rub against each other in opposite directions

What is not currently (no)
400
What type of fault occurs when to plates are moving away from each other?
What is normal fault
500
This section of the Earth is molten, and can be compared to the consistency of taffy.
What is the mantle.
500
Where does subduction of an ocean plate occur?
What is trenches
500
Volcanoes are most likely to occur where?
What is along the boundary of two colliding continental plates (convergent continental plate boundary)
500
