WebSep 11, 2024 · As rocks undergo brittle deformation, they may produce cracks in the rocks. If no appreciable displacement has occurred along these cracks, they are called joints. If appreciable displacement does occur, they are referred to as faults. We will first examine dip-slip faults, in which the movement along the fault is either up or down. Web1. When motion on a fault is vertical, it is called a dip-slip fault. Two types of dip-slip faults can be distinguished by the relative movement of the hanging wall and foot wall of a fault. a. If the hanging wall moves down relative to the foot wall, then it is a normal fault . b. hazyview optometrist

Blocks on opposite sides of the San Andreas fault move horizontally. If a person stood on one side of the fault and looked across it, the block on the opposite side would appear to have moved to the right. Geologists refer to this type fault displacement as right-lateral strike-slip. hazyview outdoor activities
