Which of these statements best describes a normal fault?

1.) one fault block moves up relative to the other one.

2.) two fault blocks move in the same direction.

3.) two fault blocks move past each other horizontally (not moving up or down).

4.) one fault block moves down relative to the other one.

4.) One fault block moves down relative to the other one. In other words, where there is a fault between the two blocks, inclined away from the left block, and the 'hanging' side moves down, this is a normal fault.If the 'hanging' side moves up relative to the other block, then it is a reverse fault.The Front Ranges of the Canadian Rockies are underlain by major reverse faults that put older rock on top of younger.
