Boundary type where many of the world's largest volcanoes occur.
What is a subduction zone?
100
Fracture in the earth's crust where movement on one or both sides has occurred.
What is a fault or fault boundary?
100
Name of the range found along the western coast of South America.
What are the Andes Mountains?
200
A fault where no movement has occurred for a long period of time.
What is a locked fault?
200
molten rock that escapes onto the earth's surface
What is lava?
200
Name of the unusually long fault found in California.
What is the San Andreas Fault?
200
Form that strong vibrations traveling through the earth take.
What are seismic waves?
200
This Washington state plateau formed when fluid, basaltic lava flowed onto the earth's surface, cooling in horizontal layers over a long period of time.
What is the Columbia Plateau?
300
Earthquake depth that causes the most damage.
What is a shallow focus earthquake?
300
eruption type formed when magma with a low gas content erupts
What is a quiet eruption?
300
Boundary where 2 plates slide or grind past each other.
What is a transform fault boundary?
300
This causes large forces to build up within the lithosphere.
What is plate movement?
400
The reason a "locked" fault is so dangerous to the surrounding area.
What is potential energy or energy built up over time?
400
eruption type formed when magma with a high gas content erupts
What is an explosive eruption?
400
Boundary formed when 2 plates collide into each other.
What is a convergent boundary?

What is the melting point?
500
Boundary formed when 2 plates move away from each other.
What is a divergent (fault) boundary?
500
This process occurs below 650 km's along subduction zones and prevents earthquakes from happening at these depths.
