3. What are "faults"?

A fault is a form of disruptive distortion, where both sides of a rock layer are extended with relative movement along the fracture (fault plane). According to the cross-section with respect to the sloping angle, we can divide the rocks into the hanging wall and the footwall. It is not possible to retrieve the actual movement at the time of the formation of the fault; the faults are mainly divided into groups based on their relative movement. For example:
