CCKH+2.1

Vocabulary:

 * Earthquake**: The shaking and trembling that results from the rock beneath Earth's surface.
 * Stress**: The force that acts on rock to change its shape or volume.
 * Shearing**: Stress that pushes a mass of rock in opposite directions.
 * Tension**: Stress that pulls on the crust, stretching rock so that it is thin in the middle.
 * Compression**: Stress that squeezes rock until it folds or breaks.
 * Deformation**: Any change in the volume or shape of Earth's crust.
 * Fault**: A break in Earth's crust where of slabs of the crust slip past each-other.
 * Strike-slip fault**: The rock on either slide of the fault where slip past each-other with little up-or-down motion.
 * Normal Fault**: a type of fault where the hanging wall slides downward; caused by tension in the crust.
 * Hanging wall**: The half of the fault that lies above.
 * Footwall**: The half of the fault that lies below.
 * Reverse fault**: a type of fault where the hanging wall slides upward.
