There isn't one singular geological term for "breakage" as it can encompass various processes and features. However, here are some geological terms related to breakage, depending on the context:

For breaking of rocks:

* Fracture: A general term for any break or discontinuity in a rock.

* Fault: A fracture in the earth's crust where there has been movement.

* Joint: A fracture in the earth's crust where there has been no movement.

* Cleavage: A tendency of a mineral to break along specific planes of weakness.

* Fissure: A narrow crack or opening, often extending downward.

* Breaching: A significant rupture or opening in a geological formation.

For breaking of geological formations:

* Erosion: The process of wearing away or breaking down rock and soil by natural forces like wind, water, or ice.

* Weathering: The process of breaking down rocks, soil, and minerals through contact with the Earth's atmosphere, water, and biological organisms.

For breaking of tectonic plates:

* Subduction: The process where one tectonic plate moves beneath another.

* Collision: The process where two tectonic plates collide.

To give you a more specific answer, I need to know the context of the "breakage" you're referring to. For example:

* Are you talking about the breakage of a rock?

* Are you talking about the breakage of a mountain?

* Are you talking about the breakage of a tectonic plate?

Once you provide more context, I can give you a more specific and accurate answer.
