Solids that are amorphous. Of which perhaps glass is the best known example. [But glass is not a mineral] Materials such as TiO2 are amorphous solids.
If a mineral doesn't have cleavage, it is said to have fracture. Fracture refers to the way a mineral breaks along irregular, non-flat surfaces. This can include minerals breaking into uneven, jagged pieces or splintering in a more random pattern.
When an isotope is unstable, it is said to be radioactive.

No, not all minerals have crystalline structures. Some minerals, called amorphous minerals, do not have a regular crystalline structure and instead have a disordered atomic arrangement. Examples of amorphous minerals include opal and glass.
They are said to exhibit fracture instead of cleavage.
That is referred to as fracturing.
When minerals do not display cleavage, they are said to have a fracture. Fracture describes the way a mineral breaks when it does not have cleavage planes. This can result in irregular or random patterns of breakage.
It means that the chemical bonds of the mineral aren't too strong along the lines and that when you break the mineral it'll break along those lines. please go to www.freewebs.com/mccniu (minerals aren't on it)
When minerals break, they can either have fracture of cleavage. Fracture is what you're looking for, and like you said, it's what happens when the mineral breaks and leaves uneven surfaces. A good example of a fractured mineral is quartz. Cleavage, on the other hand, occurs when minerals break along weak atomic bonding planes. Cleavage creates your flatter, more geometric surfaces. Look at mica. It creates what look like sheets of paper due to it's excellent cleavage.
If a mineral doesn't have cleavage, it is said to have fracture. Fracture refers to the way a mineral breaks along irregular, non-flat surfaces. This can include minerals breaking into uneven, jagged pieces or splintering in a more random pattern.
When minerals break along certain planes, it is known as cleavage. Typically, the pieces will be the same form and be bounded by smooth, flat surfaces. Cleavage is determined by the number of cleavage directions and the angle(s) between them.If the mineral breaks in an irregular, jagged or splintered edge, it is said to have a fracture.

Cleavage means to Split.Cleavage is most often used with the following 3 meanings:MITOSIS: a phase during Mitosis when cells split and multiplyGEOLOGY: The splitting of a complex crystal/mineral formation into a simpler oneINFORMAL USE: The viewable split between a woman's breasts
Cleavage
Someone said, "No. Most minerals have a variety of different colors." but that isn't true. Minerals and rocks can be classified by color, streak, luster, cleavage, hardness, and specific gravity. Hope this helps! By: Fizzycandy10
