Earth's Layers
Density
Plate Tectonics
Earthquakes
Volcanoes
100
This is the thinnest layer of the Earth.
What is crust?
100
As temperature increases, this decreases.
What is density?
100
This is the name of a boundary whose plates move toward each other.
What is Converging?
100
This is the point inside the Earth where earthquakes begin.
What is Focus?
100
This type of volcano has steep sides and erupts violently.
What is Cinder Cone?
200
This layer is made up of the crust and the upper rigid mantle.
What is the lithosphere?
200
A substance whose molecules are tightly packed together has this kind of density.
What is high density?
200
This boundary is two plates sliding past each other.
What is transform fault?
200
This is the first wave of an earthquake to be detected.
What is a P-wave?
200
This volcano is dome shaped and erupts non-explosively.
What is Shield?
300
This layer is made up of solid iron.
What is the inner core?
300
Convection takes place in the mantle with this as the heat source.
What is the core?
300
Plate tectonics take place in this layer of the Earth.
What is Lithosphere?
300
This is what a break in the earth's crust is called.
What is a fault?
300
This volcano has traits of the two other types of volcanoes.
What is Composite?
400
This layer has three different parts.
What is mantle?
400
A substance with high density will do this.
What is sink?
400
Plant and animal fossils provide evidence for this theory.
What is Continental drift?
400
This occurs from a large quake under the ocean.
What is Tsunami?
400
This is what molten rock is called when it is under ground.
What is Magma?
500
These three things increase as you move toward the center of the Earth.
What is pressure, density, and temperature?
500
The motion of warm material that rises, cools off, and sinks again, producing a continuous circulation of material is called this.
What is Convection current?
500
This man saw the perfect fit of two countries which made him think that the continents were once all together.
Who is Alfred Wegner?
500
This scale estimates how much energy is released during an earthquake.
What is the Richter Scale?
500
This is responsible for forming the Hawaiian Islands.
What is a hot spot?
