If a fault or intrusion cuts through an unconformity, the fault or intrusion is younger than all the rocks it cuts through above and below the unconformity.
If a fault or intrusion cuts through an unconformity, the fault or intrusion is younger than all the rocks it cuts through above and below the unconformity.
A normal fault is a fault in which the hanging wall has moved downward relative to the footwall.

What is the relative age of a fault that cuts across three horizontal sedimentary rock layers?A. The fault is older than the middle layer. B.The fault is younger than all the layers it cuts across.C. The fault is the same age as the top layer. D. The fault is older than all the layers it cuts across == ==
Younger than all three sediments.

This is true of normal faults. In thrust or reverse faults, the hanging wall moves up relative to the footwall and in strike slip faults, it moves horizontally relative to the footwall.
Reverse Fault
joint does not show any relative movement as fault does
A fault in which the hanging wall has moved upward relative to the footwall
