Definitions:

Displacement

The movement of a body or object from one position to another, often used in geology to describe the shift in position of rock layers along a fault.

Rotation

The act or process of an object turning around an axis, leading to day and night cycles on planets like Earth.

Thrust Faults

Thrust faults are a type of fault where the upper block, or hanging wall, moves up and over the lower block, or footwall, typically occurring at a low angle and often associated with mountain building.

Normal Faults

A geological fault in which the hanging wall moves down relative to the footwall, typically resulting from extensional forces.
