What are the physical properties used to identify minerals?

• color, luster, hardness, streak, cleavage, fracture, specific gravity, and crystal form

• shape, size, weight

• temperature, pressure, density

• smell, taste, sound

What is mineral cleavage?

• The tendency of a mineral to break along smooth, flat surfaces.

• The ability of a mineral to resist scratching or abrasion.

• The color of a mineral when it is powdered.

• The process of a mineral forming from molten rock.

What is mineral fracture?

• Mineral fracture is the process of a mineral forming fractures or cracks over time.

• Mineral fracture is the way a mineral breaks or fractures when subjected to stress or force.

• Mineral fracture is the result of a mineral being heated to a high temperature.

• Mineral fracture is the way a mineral changes color when exposed to light.

What is the difference between cleavage and fracture?

• Cleavage is the tendency of a mineral to break along curved surfaces, while fracture is the tendency of a mineral to break along straight surfaces.

• Cleavage is the tendency of a mineral to break along rough surfaces, while fracture is the tendency of a mineral to break along smooth surfaces.

• Cleavage is the tendency of a mineral to break along smooth, flat surfaces, while fracture is the tendency of a mineral to break along irregular or rough surfaces.

• Cleavage is the tendency of a mineral to break along irregular or rough surfaces, while fracture is the tendency of a mineral to break along smooth, flat surfaces.
