Vocabulary
hanging wall
 * earthquake**- the shaking and trembling that results from the movement of rock beneath Earth's surface
 * stress**- a force hat acts on rock to change it's size or volume
 * shearing**- stress that pushes a mass of rock in two opposite directions
 * tension**- stress that pulls and stretches a rock
 * compression**-stress that squeezes a rock together
 * deformation**- any change in volume or shape of earth's crust
 * fault**- a break in earth's crust where rocks slip past each other
 * strike-slip fault**- a fault where rocks in opposite directions slip past sideways
 * normal fault**- a fault that is at an angle so one block of rock is on top the other on the bottom, the bottom one is the
 * hanging wall**- a block of rock that lie above the fault
 * foot wall**- a block of rock that lies below the fault
 * fault black mountain**- a moutian made when a fault lifts up a block of rock
 * fold**- when compression bends parts of earth's crust
 * anticlines**- a fold in rock bending upward
 * syncline**- a fold in rock, bending downward
 * plateau**- large area of flat land above sea level

Introduction

 * Earthquakes are a reminder the crust can move.

Stress in the Crust

 * Earth's plates create powerful forces.

Types of Stress

 * Shearing
 * Tension
 * Compression

Kinds of Faults

 * Strike-Slip Fault
 * Normal Fault
 * Reverse Fault

Friction Along Faults

 * How a rock moves on a fault is according to friction

Mountian Building

 * Mountians formed by faulting
 * Fault block mountians
 * Mountians formed by folding
 * Anticlines and Synclines
 * Plateaus
