Texture
arrangement of grains in a rock and the way they are connected
Layering
bands of different compositions, or the alignment of inequant grains
Composition
what minerals are present
Mineral
homogenous, naturally occurring, solid inorganic substance with a definable chemical composition and internal structure of atoms in a lattice
Euhedral
where space allows
Anhedral
where space is limited
Silicate
based on the silica tetrahedron; increasing order and Si concentration; determine many properties from cleavage to viscosity of melt to temperature of melting
The Silica Tetrahedron
one silicon, 4 oxygens, strong bonds
Mineral properties
color, streak, luster, hardness, crystal shape/habit, cleavage, others
Rock
a coherent, naturally occurring solid, consisting of an aggregate of minerals or a mass of glass
Igneous rock
solidified melt, intrusive and extrusive
Sedimentary rock
aggregate of cemented pieces of preexisting rock or chemical precipitate
Metamorphic rock
changing an existing rock through heat and pressure without melting
Rock cycle
the process through which rocks are formed, changed, destroyed, and recycled into new rocks; driven by both internal and solar power
Mineral classes
Silicates, Oxides, Sulfides, Sulfates, Halides, Carbonates, Native Elements
Bedrock
rocks still attached to the Earth?s crust
Outcrop
an exposure of bedrock on the surface, either natural or man-made
