When slabs of rock are moved apart
because of tension it leads to which
of these?
A. an anticline, where the rock will fold upward.
B. a reverse fault, where the hanging wall will slide
upward.
C. a normal fault, where the hanging wall will slide
downward.
D. a strike-slip fault, where the hanging wall will
move horizontally.
When tensional stresses pull crust apart, it breaks into blocks that slide up and drop down along normal faults. The result is alternating mountains and valleys, known as a basin-and-range.
