When rocks break and move, it depends on the scale and cause of the movement. Here are a few possibilities:

* Erosion: This is the process of rocks being worn down and transported by forces like wind, water, or ice.

* Mass Wasting: This refers to the downward movement of rock, soil, and debris due to gravity. Examples include landslides, rockfalls, and mudflows.

* Tectonic Plate Movement: This is the large-scale movement of Earth's crustal plates. When plates collide or move past each other, they can cause earthquakes and rock formations to shift.

* Faulting: This is the breaking and movement of rock along a fracture in the Earth's crust.

So, the specific term for what happens when rocks break and move depends on the context.
