There are different types of fracture, such as:
* Conchoidal fracture: This is a smooth, curved fracture, like the inside of a seashell. It is often seen in quartz and obsidian.
* Hackly fracture: This is a jagged, uneven fracture, with sharp edges. It is often seen in metals.
* Fibrous fracture: This is a fracture that produces long, thin fibers. It is often seen in asbestos.
* Irregular fracture: This is a fracture that is simply uneven and does not fit any of the other categories.
So, the answer is fracture.
