Earth's Formation
Earth's Structure
Plate Tectonics
Earthquakes
Volcanoes
100
This is the unifying theory of geology.
What is understanding the Universe
100
This is the separation of Earth's layers after formation
What is differentiation
100
The boundary where plates are spreading apart
What is divergent
100
The point in which the Earth first moves creating an earthquake.
What is focus or hypocenter
100
Molten rock at the surface of the Earth is called this.
What is lava
200
13.8 billion years ago, this occurred.
What is the big bang
200
This is the boundary between the crust and mantle
What is the Moho
200
When one plate goes under another it is called
What is subduction
200
The fastest seismic wave
What is P or primary
200
The type of lava that has low viscosity and produces shield volcanoes.
What is basaltic
300
We know that the Universe is expanding because of this phenomenon with light waves.
What is red shift
300
The crust plus the upper mantle are collectively known as this.
What is the lithosphere
300
This is created when polar reversals occur at a spreading center
magnetic striping (or anomalies)
300
This type of seismic wave does the most damage.
What is surface waves
300
This category of rock is formed by volcanism.
What is igneous
400
This is the disk shaped feature that forms a new solar system.
What is a circumstellar disk.
400
This type of crust is light, thick, and typically composed of felsic minerals.
What is continental crust
400
The theory that Alfred Wegener developed.
What is continental drift
400
S-waves appear after p-waves because they cannot travel through this.
What is liquid
400
This feature is typically found on the overriding plate of a subduction zone.
What is volcanic arc
500
This is what happens when a star explodes
What is a supernova
500
This is the only layer of the Earth that is not solid
What is outer core
500
The oldest ocean crust is found here.
What is around the edges of continents, or far away from spreading center.
500
Wadati-Beniof earthquakes are found in this type of plate boundary.
What is subduction zone
500
Hawaii is an example of this type of volcanism
What is hot spot
