100
This is the process where new oceanic crust forms along a mid-ocean ridge and older oceanic crust moves away from the ridge.
What is Seafloor Spreading?
100
This is the Principle of Superposition.
Answers will vary, but should be similar to: "What is in undisturbed rock layers, the oldest rocks are on the bottom."
100
This type of plate boundary occurs when the plates move away from each other.
What is a Divergent Plate Boundary?
100
This type of plate boundary creates a normal fault.
What is a Divergent Plate Boundary?
100
Volcanoes can form at these two types of plate boundaries.
What are Divergent Plate Boundaries, and Convergent Plate Boundaries (O-C).
200
This is the cycling of materials based on differences in temperature and density. It is the cause of all plate motions.
What are "Convection Currents?"
200
This type of volcano has recently erupted but does not have any current volcanic activity.
What is a "Dormant" volcano?
200
Which type of plate boundary creates a strike slip fault?
What is a Transform Plate Boundary?
200
This type of fault occurs when two blocks of rock are pushed together.
What is a Reverse Fault?
200
This is another name for a long underwater chain of volcanoes between two diverging plates.
What is a Mid-Ocean Ridge?
300
This type of force moves a tectonic plate by grabbing the bottom of the plate as the convection current in the mantle moves along.
What is Basal Drag?
300
This section of rock is found above the fault line, and is important to focus on as you determine if it is a Normal or Reverse fault.
What is the "Head Wall?"
300
What type of plate boundary is shown here? 
What is a Convergent Boundary between an Oceanic and Continental Plate?
300
This type of fault is shown below.
What is a Reverse Fault?
300
Which type, or types, of magma create an explosive eruption.
What are Felsic & Intermediate magmas?
400
This type of force is shown here. 
What is Ridge Push?
400
This type of fold creates a downward "U" shape and is considered a "basin" in its three dimensional form.
What is a "Syncline?"
400
What type of surface features would you expect to find at this plate boundary? 
What are an Ocean Trench, Volcanoes, and Faults?
400
This type of fault is shown here.
What is a Strike Slip Fault?
400
Hawaii is an example of this type of volcano.
What is a Shield Volcano?
500
Why is the Theory of Plate Tectonics considered a better explanation than the Continental Drift Hypothesis?
Answers will vary, but should be similar to:
"Plate Tectonics us considered a unifying theory because it also helps explain aspects about the age of rocks, differences between oceans and continents, as well as the connecting ideas about where and how volcanoes form and when and where earthquakes occur."
500
This is a break in Earth's lithosphere where one block of rock moves toward, away from, or past another.
What is a Fault?
500
What type of natural hazard(s) could occur at this plate boundary?
What are Earthquakes & Volcanic Eruptions?
500
This type or types of boundary, can cause an earthquake.
What are Divergent, Convergent, and Transform Boundaries.
500
Hawaii formed at this type of location that creates volcanoes.
What is a Hot Spot?
