Document Summary
Strain change in shape that deformation causes. Stress the push, pull, or shear that a material feels when subjected to a force; the force applied per unit area over which the force acts. Elastic/ductile deformation objects change shape without visibly breaking. Tension a rock is pulled apart. Shear stress one side moves sideways past the other side. Pressure special stress condition where the same push acts on all sides of an object. Fault a fracture on which sliding occurs. Thrust fault a gently dipping reverse fault; the hanging wall block moves up the slope of the fault. Reverse fault a steeply dipping fault on which the hanging block slides up. Strike slip fault one block slides past another horizontally, parallel to to the strike line. Normal fault hanging wall block moves down the slope of the fault. Anticlines folds that have arch like shapes in which the limbs dip away from the hinge.
