faults fit(s) this type of movement?
A. Normal fault.
B. Reverse fault (thrust fault).
C. Right lateral fault.
D. Left lateral fault.
E. Left-lateral normal fault.
(2) Which of the following movements describes the “left-lateral nor-
mal fault”?
A. The movement is vertical, the hanging wall moves up relative to
the foot wall.
B. The movement is horizontal (or lateral), each block moves to the
right of the opposite block.
C. The movement is horizontal (or lateral), each block moves to the
left of the opposite block.
D. The movement is combined by the normal fault movement and
left-lateral fault movement.
