Mineral:
Naturally occurring
Gypsum
Solid
Definable chemical composition
Orderly arrangement of atoms (in crystal lattice)
Crystal: a single solid continuous crystalline solid bounded by flat crystal faces

diamond
A polymorph - two different
minerals of identical composition
(here graphite)
2
Shares two oxygen
Shares two-three oxygen
SiO44Independent (Olivine)

Rock Groups
Rock - coherent, naturally
occurring aggregate of minerals
(and/or glass)
Bedrock (attached to crust)
Outcrop (exposed)
4
Formed from freezing of molten
rock (magma): Igneous Rock
5
Formed from cementing of fragments or
precipitation out of water: Sedimentary
Formed by subjecting
other rocks to high
pressures and
temperatures (in solid
state - no melting
allowed!): metamorphic
