normal fault A normal fault occurs when the hanging wall moves down (Divergent Boundaries release tension and rocks slide down) reverse fault A reverse fault occurs when the hanging wall moves up (Convergent Boundaries push rocks up and over)
How is a thrust fault formed? A thrust fault is formed when compressive stresses act over great distances. A thrust fault is a reverse fault in which the fault plane dips 45 degrees or less from the horizontal.
What type of fault occurs when rock on opposite sides of a fault plane move horizontally past each other? A Strike-slip Fault A Strike-slip Fault
How do Horsts and Grabens differ? Horsts Horsts are large blocks of crust that have been thrust upward between faults… Grabens Grabens are large blocks of crust that have dropped down between faults…
