100
Wegner's theory that the continents shifted.
What is Continental Drift.
100
Volcanoes of this type are broad and dome shaped.
What is shield volcanoes.
100
Strike-Slip Faults are similar to this type of boundary.
What is a transform-fault boundary.
100
An earthquake scale that uses Roman Numerals to denote different intensities of earthquakes.
What is the Mercalli Scale.
200
The very center of the earth which is comprised of solid iron and nickel.
What is the inner core.
200
Tectonic plates move at this approximate distance per year.
What is a few centimeters.
200
Volcanoes of this type erupt with ash and rock, but not with lava.
What is cinder cone volcanoes.
200
At a reverse fault, this wall is higher than the other.
What is hanging wall.
200
These waves cause the most damage.
What are surface waves.
300
The layer of the earth that contains hot, flowing rock and also goes by the name of asthenosphere.
What is the lower mantle.
300
A type of boundary where two plates move away from each other.
What are divergent plates.
300
Volcanoes of this type erupt with lava and ash.
What is composite volcanoes.
300
At this type of fault, there is no change in height.
What is the strike-slip fault.
300
A magnitude at or above this value would indicate major damage.
What is 6.0.
400
Where convection and convection currents take place.
What is the mantle.
400
Most plates contain these two types of crust.
What are oceanic and continental crust.
400
The result of one convergent plate sliding under another, and also one of the causes of volcano formation.
What is subduction.
400
When the earth's crust is stretched apart or cracked at a normal fault line, this wall will move downward and will also cause basins to form.
What is the hanging wall.
400
Factors for earthquake damage include magnitude of earthquake, distance from the epicenter, type of construction, and this.
What is local geology.
500
The earth's layers that make up the lithosphere.
What are the crust and the upper mantle.
500
The San Andreas Fault Line is on the boundary of these two plates.
What are the Pacific Plate and the North American Plate.
500
This thin area of lithosphere lies away from plate boundaries and may give way to volcano formation.
What is a hot spot.
500
Along the San Andreas Fault Line, this has caused the Transverse Ranges to lift.
What is compression due to plate movement.
500
This type of ground would roll and shake more in the event of an earthquake.
What is loose, soft, wet ground.
