100
This type of volcano is wide and flat and produced by many gentle basaltic eruptions. 
What is a shield volcano?
100
Earthquake are typically found along what types of geologic features?
What are plate boundaries and faults? 
100
This type of plate boundary occurs when two plates move apart. 
What is a divergent boundary?
100
This is the state of matter of the outer core. 
What is liquid? 
100
This is the name of the last supercontinent.
What is Pangea?
200
Major examples of this explosive volcano are Mt. St. Helens and Mt. Vesuvius.
What is a composite volcano?
200
This is the point on Earth's surface that is used to describe an earthquake's location.
What is the epicenter?
200
Crust is neither created or destroyed at this type of plate boundary. 
What is a transform boundary?
200
The inner core is made of solid iron and nickel due to this. 
What is the pressure?
200
What is the primary reason why Wegener's theory of continental drift was rejected?
What is he lacked a mechanism of plate movement? 
300
This type of volcano is made of piles of pyroclasts and is typically fairly small. 

What is a cinder cone?

300

This type of earthquake wave does not travel through liquids, helping seismologists determine the interior structure of Earth. 

What are s-waves?

300
This type of fault is produced by compression forces. 
What is a reverse fault? 
300

The crust and uppermost portion of the mantle comprise this.

What is the lithosphere?
300

This is the record of Earth’s magnetic field recorded in igneous rocks at the time of their formation. 

What is paleomagnetism?
400
This type of volcano produces massive, catastrophic eruptions due to the size of the underlying magma chamber. 

What is a caldera?

400

A magnitude 8 earthquake is this many times stronger than a magnitude 5 quake.

What is 1000 times? 

400
The Himalaya Mountains form at what type of plate boundary? 
What is a continental-continental convergent boundary?
400
This the line between the crust and mantle.

What is the Moho? 

400
These are the two discoveries that eventually led to widespread acceptance of the theory of plate tectonics. 
What are paleomagnetism and seafloor spreading?
500
This type of volcano is associated with divergent boundaries, like that found in Iceland. 

What is a fissure volcano?

500

This is why tsunamis are so destructive by the coast, but are barely noticeable over the open ocean. 

What is the seafloor rises along the coast, causing a tsunami's energy to compress and increase wave height. 

500
When two tectonic plates collide, the plate that ________________ is the __________ plate. 

What is subducts and denser. 

500
This layer of the mantle is found below the lithosphere and produces convection currents that drive plate tectonics.
What is the asthenosphere?
500
What reptile fossil is found in both South America and Africa, serving as strong evidence that those continents were once together?
What is mesosaurus?
