Vocabulary:
earthquake: Is the shaking and trembling that results from the movement of rock beneath the Earth's hard surface.

stress: A force that acts on rock to change its shape or volume.

shearing: Stress that push a mass of rock in two opposite directions.

tension: A force that pulls on the crust, stretching the rock so that it becomes thinner in the middle.

compression: It is a force that pushes rock together, making it higher in the middle.

strike-slip fault: A fault made by shearing.

normal fault: Faults from tension inside of Earth's crust.

reverse fault: Compression produces reverse faults.

mountain building: Made by normal faults.

deformation: It is when there is a change in shape or volume in the Earth's crust.

fault: When Earth's crust breaks and slabs of rock slip past each other.

hanging wall: A block of rock that forms the upper half in a fault.

fault-block mountain: A mountain that was formed under a normal fault that has uplifted a block rock.

folds: After Earth has been compressed, a bend of rock forms where the compressed place was.

syncline: After compression in Earth's crust that causes a downward fold in rocks.

plateau: A landform that has more or less land level with and is higher than sea level.

Outline

 * Types of stress
 * Shearing
 * Pushes rocks in opposite directions
 * Causes rocks to break
 * Causes rocks to slip apart
 * Causes rocks to change shape
 * Tension
 * Stretches rock: thin in middle
 * Like pulling on warm gum
 * Occurs: two plates moving apart
 * Stress force
 * Compression
 * Squeezes rock
 * Rock will fold or break
 * One plate will push another
 * Like giant trash compactor(Rock)
 * Deformation
 * Earth's crust changes volume/shape
 * Crust changes slowly
 * Speed time=change in deformation(to see)
 * Crust: bend, stretch, tilt, fold, or slide
 * Kinds of fault
 * Strike-slip fault
 * Shearing causes Strike-slip faults
 * Normal fault
 * Tension forces causes Normal faults
 * Reverse fault
 * Compression causes Reverse faults
 * Faults
 * Hanging wall
 * footwall
