100
This is the stored energy of a particle because of its position. 
What is potential energy?


100

The match of these coastlines gave Wegener his first piece of evidence for continental drift.

What is South America and Africa?

100
This layer of the Earth is its outermost layer. 
What is the crust?
100
At this type of plate boundary, tectonic plates move apart. 
What is a divergent plate boundary?
100
This is where an earthquake starts. 
What is the focus?
200
These are substances in which the particles can flow freely. 
What are fluids (liquids and gases)?
200

This refers to the rock markings that glaciers have left behind.

What is paleoglaciation?

200
This layer of the Earth is its thickest layer. 
What is the mantle?
200
This occurs when two oceanic plates collide. 
What is subduction?
200
This type of seismic wave only travels through solids. 
What is secondary waves. 
300
This is the movement of a fluid caused by density differences.
What is a convection current?
300
These islands were formed when a tectonic plate passed over a stationary hot spot.
What is the Hawaiian Islands?
300
This layer of the Earth is liquid. 
What is the outer core?
300
The mountains of the Himalayas formed as a result of this. 
What is continental-continental plate convergence?
300
This is a number that rates the strength of an earthquake. 
What is magnitude?
400
This is the transfer of energy by waves. 
What is electromagnetic radiation?
400
This is the process in which Earth's magnetic field completely reverses its direction. 
What is magnetic reversal?
400

This layer of Earth has temperatures from 50000C to 60000C.

What is the inner core?
400
This causes tectonic plates to slide past each other. 
What are convection currents in the mantle?
400
This type of volcano is produced from very thick magma. 
What is a composite volcano?
500
These are materials that do not transfer heat easily. 
What are insulators?
500
This is formed when magma cools and hardens when it breaks through Earth's surface at a spreading ridge. 
What is new sea floor?
500
This layer of Earth is composed of partly molten rock containing iron and magnesium. 
What is the mantle?
500
This produces a volcanic island arc. 
What is oceanic-oceanic plate convergence?
500
This type of volcano forms over hot spots. 
What is a shield volcano?
