What Rocks above the fault surface are forced up and over the rocks below the fault surface?

The rocks that are forced up and over the rocks below the fault surface are referred to as "hanging wall" rocks. This occurs in a specific type of fault known as a thrust fault, where compressional forces cause the hanging wall to move upward relative to the footwall, which is the block of rock below the fault surface. This movement can result in significant geological features, such as mountain ranges.
