A naturally occurring inorganic solid with a crystalline form.
mineral
The color of a mineral in powdered form
streak
when a mineral breaks along preferred planes of weakness creating sets of smooth parallel sides
cleavage
minerals the break with irregular surface exhibit.
fracture
the physical property that measure a mineral’s resistance to scratching
