3. Which is the way a mineral breaks apart in an irregular way? Mineral Cleavage Crystal Fracture

The way a mineral breaks apart in an irregular way is referred to as Fracture.

Explanation:

Minerals have two main types of breakage patterns: cleavage and fracture.

1. Cleavage: This is the tendency of a mineral to break along flat, even surfaces. Minerals that exhibit cleavage will break in a predictable manner, reflecting their internal crystal structure.

2. Fracture: Fracture occurs when a mineral breaks in a more irregular or uneven manner. This type of breakage does not follow any particular planes of weakness in the crystal structure, resulting in a jagged or rough surface.

So, in summary, the correct term for the irregular breaking apart of a mineral is Fracture.
