Here's why:

* Reverse Fault: In a reverse fault, the hanging wall (the block above the fault plane) moves upwards relative to the footwall (the block below the fault plane). This upward movement causes the hanging wall to have a steep dip (angle) relative to the horizontal.

* Dip: The dip refers to the angle at which a rock formation is tilted.

Other types of faults:

* Normal Fault: The hanging wall moves downwards relative to the footwall.

* Strike-Slip Fault: The blocks move horizontally past each other.
