Continental crust that extends down into the mantle

100
Elastic Strain
when a material (crust) bends and stretches like a rubber band
100
Plate tectonics
Plate movement, earthquakes, volcanoes
100
3 kinds of Seismic Waves
Primary Secondary Surface
100
Igneous Rocks are described as...
INTRUSIVE
200
The main "force" causing initial pressure on the crust/rocks.
STRESS (what you're feeling right NOW)
200
Plastic Deformation
a material (crust) bends and stretches beyond its elastic capacity
200
A Fault
is where the crust moves/earthquakes happen
200
Primary Waves
FIRST type of seismic wave we experience during an earthquake
200
Basaltic Magma-What does it have?
that has the most iron/Least silica
300
Focus
Point BENEATH the crust where the waves originate.
300
Tensional Stress
stress called that pulls crust/rock apart
300
A Normal Fault
fault that experiences the "pulling apart" of the crust
300
Surface Waves
the most destructive type of seismic wave/LAST to occur
300
Silica
What makes volcanoes extra explosive/STICKY substance found in continental crust.
400
Tension
The stress that pulls the rock material APART at fault zones
400
Shear Stress
stress that causes a material to twist or slide
400
What does the crust do at a Reverse Fault?
the type of fault that occurs most often at *convergent* plate boundaries. Crust comes together.
400
What occurs On FAULT zones!
Where most earthquakes occur here
400
Orange County
Where Ms. Sinks Lives on the weekends
500
Compression
Stress that occurs when the rock material is squished or squeezed closer together.
500
Elastic and Plastic
two types of STRAIN
500
San Andreas Fault is WHAT kind of fault?
a strike-slip fault
500
Primary Secondary Surface
the three types of seismic waves
500
