This is the most recent super-continent that came together around 200 million years ago.
Pangaea
100
This was the "how" or the mechanism for the Continental Drift theory that Harry Hess discovered.
What is sea-floor spreading.
100
This layer of the earth is the thinnest and is composed of loose rocks and soil.
What is the crust?
100
This is the type of rock that is formed by cooling magma or lava.
What is igneous?
100
This is the most destructive type of wave.
What are surface waves?
100
Seen below, number 3 is pointing to this; a circular basin or depression.
What is the crater?
100
This is the land form created at a continental to continental convergent boundary.
What are folded mountains?
200
This is the scientist that put forward the Continental Drift Theory.
Who is Alfred Wegener
200
These are the currents in the mantle that power the movement of the plates.
What are convection currents.
200
This layer of the Earth is composed of liquid iron and nickel. It also creates the Earth's magnetic field.
What is the outer core.
200
This is the most explosive type of volcano. It is also made up of layers of ash and lava.
What is the composite or stratovolcano.
200
These type of seismic waves can travel through solids but not liquids.
What are S-waves (secondary).
200
Seen below, number 11 is pointing to this; the large underground pool of molten rock sitting underneath the Earth's crust.
What is the magma chamber?
200
Subduction zones create these two land forms.
What are volcanoes and trenches?
(volcanic arc of islands also excepted)
300
The puzzle like fit of these two continents helps support the continental drift theory.
What are Africa and South America.
300
The plate that subducts at a subduction zone is always this.
What is denser?
300
This layer of the Earth is the thickest and is composed of magma.
What is the mantle?
300
The Hawaiian islands are this type of volcano. They have low, gentle slopes and are the largest type of volcanoes.
What is shield volcano.
300
This scale, which is numbered 1-10, measures the strength or magnitude of an earthquake.
What is the Richter scale.
300
Seen below, number 1 is pointing to this; the small pieces of pulverized rocks, minerals, and volcanic glass created during an eruption.
What is the ash cloud?
300
As seen here, at an oceanic to oceanic divergent boundary this type of landform is formed. 
What is a mid-ocean ridge?
400
This is why other scientists did not originally support Continental Drift Theory.
There was no known mechanism as to how the continents could be moving.
400
These TWO types of plate boundaries create subduction zones.
What are convergent oceanic to oceanic and convergent oceanic to continental?
400
This layer of the Earth is composed of solid iron and nickel.
What is the inner core?
400
This volcano has steep angled sides, throws blobs of lava in the air that fall as cinders, and is build over a short period of time.
What is a cinder cone volcano.
400
These waves are called "push/pull" waves because they compress and extend as they move through the earth.
What are p-waves (primary).
400
Seen here, this type of fault is caused by shearing forces.
What is a strike-slip fault?
400
This type of land form is created at a continental to continental divergent boundary.
What is a rift valley?
500
An example of this type of evidence for the Continental Drift Theory is mountains on different continents matching up as if they were created together and then separated.
What is rock layer and land form evidence?
500
When age is compared, continental is this compared to oceanic.
What is older?
500
The crust and the upper mantle together make this.
What is the lithosphere?
500
Volcanoes that are sleeping or have not erupted recently, but may erupt again are called this.
What is dormant?
500
The point within the earth where the earthquake originates.
What is the focus.
500
Seen here in this picture, this type of fault is created when the hanging wall moves downward compared to the foot wall. It is caused by tension forces.
What is a normal fault?
500
These two land forms are created at an oceanic to oceanic convergent boundary.
What is a trench and a volcanic arc of islands?
600
These scratches in the rock on different continents provide Glacial evidence for the continents once being all together.
What are striations.
600
Continental crust is thicker and made of granite. Oceanic crust is thinner and made of basalt. This crust is denser.
What is oceaniccrust?
600
The convection currents take place in this part of the mantle (also known as the middle mantle).
What is the asthenosphere?
600
Active volcanoes can be found at convergent and divergent boundaries, but they can also be found in these spots in the middle of a plate.
What is a hot spot?
600
These giant waves are created by underwater earthquakes or landslides and can devastate coastal areas. They travel an average of 450 mph.
What are tsunamis?
600
As seen here in this picture, reverse faults are created when the hanging wall moves upwards compared to the footwall. This type of force creates these faults.
What is compression?
600
This is the land form created at a transform boundary.
What is a fault?
700
Seen here, this type of evidence supports the Continental Drift Theory because of the difficulty these ancient organisms would have had traveling to all these continents.
What is fossil evidence?
700
Sing this song, to the tune of the Adam's Family, to remember what is happening at the plate boundaries.
What is
Da-da-da-dah (snap snap) Da-da-da-dah (snap snap) Da-da-da-dah Da-da-da-dah Da-da-da-dah (snap snap)
Convergent is colliding
Divergent is dividing
Transform is sliding
We are the plate boundaries
700
As you get deeper inside of the Earth the temperature and pressure do this.
What is increase?
700
This is the active volcano and earthquake area found around the Pacific Rim.
What is the Ring of Fire?
700
This is the number of seismic stations required to triangulate the epicenter of an earthquake.
What is three?
700
As seen here, igneous intrusions are created when magma cools under the Earth's crust. The label e is this type of igneous intrusion.
What is a sill?
700
These two land forms are created at an oceanic to continental boundary.
What is a trench and volcanoes?
