As the rocks of the crust undergo stress, they slowly change shape and volume. They also move up or down or sideways. Deformation: Deformation The breaking, tilting and folding of rocks. Three types Compression Tension ShearingCompression: Compression Squeezes the rocks of the crust Moves rocks closer together, making them denser and smaller in volumeTension: Tension Pulls on the rocks of the crust, causing them to stretch out over a larger areaShearing: Shearing Pushes rocks of the crust in two opposite directionsFault: Fault A break or crack along which rocks move The block of rock above the fault is the hanging wall The block of rock below the fault is the foot wallNormal Fault: Normal Fault If tension is acting on a fault, the hanging wall will move down relative to the foot wall.Reverse Fault: Reverse Fault If compression is acting on a fault, the hanging wall will move up relative to the foot wall.Thrust Fault: Thrust Fault When compression causes the hanging wall to slide over the foot wall.Lateral / Strike-Slip Fault: Lateral / Strike-Slip Fault One block moves to the left or right in relation to the other blockFolds: Folds Sometimes when stress is applied to the rocks of the crust, the rocks bend but do not break An upward fold is called an anticline A downward fold is called a syncline You do not have the permission to view this presentation.
