_____ is the irregular break of a mineral
Sati [7]

Answer:

I'm not sure if this is right, but i believe the right answer would be fracture.

Explanation:

In geology, a fracture is any separation in a geologic formation, such as a joint or a fault that divides the rock into two or more pieces. A fracture will sometimes form a deep fissure or crevice in the rock. Fractures are commonly caused by stress exceeding the rock strength, causing the rock to lose cohesion along its weakest plane.

hope this helps :)
