100
This is the hot material that comes out of a volcano
What is lava?
100
This wave comes first.
What is a primary wave? (also accept P waves)
100
These shifting plates are more than meet the eye, sliding side to side.
What is a transform boundary?
100
This is the denser, wetter plate.
What is an oceanic plate?
100
The layer we walk on. Pizza and Pie also have this.
What is the crust?
200
This material is a combination of mud, water, and lava.
What is a lahar?
200
This wave comes after the first wave.
What is a secondary wave? (also accept S wave)
200
These plates pull apart from one another. May be associated with the book.
What is divergent?
200
The less dense plate. Not to be confused with the breakfast of the same name?
What is a continental plate?
200
The metal ball in the center of the earth.
What is the inner core?
300
This volcano erupted in Washington State in 1980.
What is Mount St. Helens?
300
A scale to measure an earthquake.
What is the Richter Scale?
300
These destructive plates do as the Beatles say and, "Come Together".
What is convergent?
300
This landmass contained all of the continents known today as one.
What is Pangea?
300
This layer is made up of iron and Nickel. However it is a liquid.
What is the outer core.
400
How a liquid resists flowing.
What is viscosity?
400
A P wave can travel through these materials.
What are all materials?
400
When one plate moves underneath of another.
What is a subduction zone?
400
Either of the two supercontinents. (One point for one, two for both).
What is Laurasia? What is Gondwana?
400
Convection currents occur in this layer. Located below the surface.
What is the mantle?
500
This is the area with the most volcanoes. This is a volcanic reigon fed by underlying mantle.
What is The Ring of Fire? What is a hot spot?
500
This device contains a pen and paper. This is the product of the device.
What is a seismometer? What is a seismograph?
500
These two underwater features are created by the divergent boundaries. (Two Points)
What are Mid-Ocean Ridges and Rift Valleys?
500
The theory that the continents are drifting apart from one another, as well as the man that originally came up with the idea.
What is Continental Drift Theory? Who is Alfred Wegener?
500
These are the rigid and plastic layers inside of the Earth. Easily recognized due to their fancy names. (Two Points).
What are the Lithosphere and Asthenosphere?
