Earth's Layers
Earthquakes
Faults
Volcanoes
Continental Drift
100
The thickest layer of the Earth
What is the mantle?
100
The origin of an earthquake.
What is the focus?
100
Faults are considered this.
What are a breaks in the lithosphere where blocks of rock move?
100
An opening in the crust where magma can come to the surface.
What is a volcano?
100
The plate boundary where tectonic plates push together.
What is convergent?
200
The hardest and coolest layer of the Earth
What is lithosphere?
200
These waves come from earthquakes
What are seismic waves?
200
The block of rock moves "up hill" at this type of fault.
What is a reverse fault?
200
One of these may come out of a volcano.
What are ash, lava, gasses, and/or rock.
200
Plate boundary where tectonic plates spread apart.
What is divergent?
300
A thick tar-like hot rock
What is the asthenosphere?
300
Earthquakes under the surface of the ocean can cause these.
What are tsunamis?
300
When an object presses on, pulls on or presses against another object, you get this.
What is stress?
300
This volcano is more flat than a cinder cone volcano
What is a shield volcano?
300
The plate boundary where tectonic plates scrape past each other.
What is transform
400
A solid metal layer
What is the inner core?
400
The point on the surface directly above the beginning of an earthquake.
What is the epicenter?
400
When blocks of rock suddenly slip along a fault this type of shaking of the ground will happen.
What is an earthquake?
400
Mt. St. Helens, in the state of Washington, is not a shield, or cinder cone volcano but this type of volcano.
What is a composite volcano?
400
The scientist that created the idea of continental drift.
Who is Alfred Wegener?
500
The most dense layer.
What is the inner core?
500
The instrument used to detect seismic activity.
What is the seismograph?
500
Blocks of rock move side-ways on either side of the fault plane along this type of fault.
What is a strike-slip fault?
500
This suffocating volcanic effect may affect more area than the other volcanic effects.
What is volcanic ash?
500
This method of heat transfer is considered the reason continental and oceanic crust moves.
What is convection?
