Earth Layers
Earthquakes
Volcanoes
Fault Lines
Random
100
This layer is plastic allowing tectonic plates to move.
What is the asthenosphere?
100
This type of seismic wave is the most destructive.
What is a S-wave?
100
The Hawaiian Islands formed from this.
What is a hot spot?
100
Strike-slip faults are created by this type of boundary.
What is a transforming boundary?
100
One large continent that composed of all of the current day continents
What is Pangaea?
200
This layer makes up the tectonic plates.
What is the lithosphere?
200
The minimum number of stations used to locate the epicenter of an Earthquake.
What is 3?
200
This type of volcano has the possibility of erupting in the future.
What is a dormant volcano?
200
Sea-floor spreading takes place along this boundary
What is a divergent boundary?
200
The point UNDERGROUND at which the Earthquake begins.
What is the focus? Reminder: The epicenter is the position above ground on the Earth's surface.
300
This layer of the Earth has the highest pressure and temperatures.
What is the inner core?
300
Seismologist calulate the magnitude of an Earthquake by looking at these TWO features on a seismograph.
What is the S-P lag (distance from the earthquake) and the amplitude?
300
Darkening of the skies is most likely to happen after which type of eruption.
What is an explosive eruption?
300
A type of boundary that is formed when plates collide
What is convergent boundary?
300
This term describes how lava will flow.
What is the viscosity?
400
The ultimate cause for tectonic plate movement
What is convection of the asthenosphere? (Just convection is an acceptable answer)
400
As seismic waves travel farther, what happens to the difference in times of P-waves and S-waves
What is become bigger as the distance increases?
400
This type of volcano has pyroclastic material ejected and calm lava flow.
What is composite volcano?
400
New oceanic lithosphere forms as a result of
What is sea-floor spreading?
400
A change in the original shape of a material. When we are talking about earthquakes, it is due to stress and strain.
What is deformation
500
The deep interior of the Earth can be mapped using
What is seismic waves?
500
Seismologist use this to determine when an earthquake started and where it is located
What is a seismogram?
500
This term is used to explain when magma creeps outside of the magma chamber and solidifies as an igneous rock.
What is a dike?
500
What forms when continental crust converges with another continental crust
What is a mountain range (folded mountain range)? Ex: Himalayas
500
List the type of fault line that created Andes mountains in South America. Make sure to include what types of Earth's crust involved.
