Examine the pictures carefully. Decide what kind of fault is shown in each. Then explain how movement along the fault caused the changes you see. Write your answers in the spaces provided. Evidence of Movement Along Faults 1. Fault 1 Type of fault: _____________________ The two blocks of rock on either side of the fault moved ______________in __________directions. The road and fences broke at the_____________ line, and the two halves of each structure were displaced. 2. Fault 2 Type of fault: _________________ The block in the bottom of the picture (the_____________ wall) moved upward along the fault. The river could no longer flow__________ the fault. Instead, the water collected at the base of the fault (on the __________ wall) to form a ____________. Without water flowing into it, the part of the river on the ______________wall ran dry. 3. Fault 3 Type of fault: _________________ The block in the bottom of the picture (the _____________ wall) moved _____________ along the fault, creating a ______________ where the river crosses the ________________.
