Fault Diagram Questions A) What type of strike-slip fault is shown in the diagram in Figure la? B) What type of strike-slip fault is shown in the diagram in Figure 1b? C) Referring to Figure 2, in a normal fault does the block containing the hanging wall move up or down with respect to the footwall block? D) Still referring to Figure 2, in a thrust or reverse fault does the block containing the hanging wall move up or down with respect to the footwall block?

Question
Fault Diagrams Several fault diagrams and related questions to get you visualizing movement along a fault. Your textbook and the Canvas modules will be very helpful here. Enter your answers in the text field below. Faults, the fractures in rock along which movement or slip has occurred, are classified according to the orientation of the fault and the relative movement of the rock on either side of the fault. Strike-slip faults In the strike-slip fault, the fault plane-the plane or surface along which movement occurs-is generally vertical. Movement of the blocks on either side of the fault is parallel to the strike of the fault. They can be further defined by the direction in which the ground on either side of the fault appears to have moved. For example, if, as you look across the fault, the block on the opposite side seems to have slipped to the left then the fault is called a left-lateral strike-slip fault. If the slippage has been to the right, then the fault is called a right-lateral strike-slip fault. (Above) Figure 1a |(Above) Figure 1b Normal faults and reverse faults Thrust or reverse fault- -Normal fault Figure 2 above displays two other types of faults, normal faults and thrust (reverse) faults. The block containing the hanging wall "hangs over" the block containing the footwall. The footwall is the surface on which you would put your feet if you walked up the plane of the fault. The hanging- wall block would "hang over" your head.
