Know the definitions of the following words and be able to match them on the test:
Hardness – the ability to resist scratching
Color – in some minerals, it is very unique, like bright blue
Streak – color produced by a mineral’s powder on a piece of tile
Luster – how a mineral reflects light
Density – the ratio of the mass of a substance to its volume
Crystal System – general shape of a mineral, like cubic
Cleavage – the way a mineral splits along a flat surface
Fracture – how a mineral looks when it breaks apart irregularly
Magnetism – when a compass reacts to the presence of a mineral
Fluorescence – the ability to glow under UV light
