TermDefinition
Ion an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
Crystal a piece of a homogeneous solid substance having a natural geometrically regular form with symmetrically arranged plane faces.
Inorganic not consisting of or deriving from living matter.
Mineral a solid inorganic substance of natural occurrence.
Silicates a salt in which the anion contains both silicon and oxygen, especially one of the anion SiO42−
Cleavage a sharp division; a split.
Crystallization is also a chemical solid–liquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs.
Igneous Rock is formed through the cooling and solidification of magma or lava.
Metamorphic Rock is a type of rock which has been changed by extreme heat and pressure.
Metamorphism alteration of the composition or structure of a rock by heat, pressure, or other natural agency.
Precipitate cause (a substance) to be deposited in solid form from a solution.
Rock Cycle an idealized cycle of processes undergone by rocks in the earth's crust, involving igneous intrusion, uplift, erosion, transportation, deposition as sedimentary rock, metamorphism, remelting, and further igneous intrusion.
Density the degree of compactness of a substance.
Fracture the cracking or breaking of a hard object or material.
Hardness the quality or condition of being hard.
Luster a gentle sheen or soft glow, especially that of a partly reflective surface.
Streak a long, thin line or mark of a different substance or color from its surroundings.
Lava hot molten or semifluid rock erupted from a volcano or fissure, or solid rock resulting from cooling of this.
Sediment matter that settles to the bottom of a liquid; dregs.
Sedimentary Rock Rock that has formed through the deposition and solidification of sediment, especially sediment transported by water (rivers, lakes, and oceans), ice ( glaciers ), and wind.
Sedimentation Sediment is the accumulation of sand and dirt that settles in the bottom of lakes.
Extrusive relating to or denoting rock that has been extruded at the earth's surface as lava or other volcanic deposits.
Intrusive causing disruption or annoyance through being unwelcome or uninvited.
Volcanic Rock is a rock formed from magma erupted from a volcano
Magma hot fluid or semifluid material below or within the earth's crust from which lava and other igneous rock is formed by cooling.
Rock the solid mineral material forming part of the surface of the earth and other similar planets, exposed on the surface or underlying the soil or oceans.
Vein a fracture in rock containing a deposit of minerals or ore and typically having an extensive course underground.
Gemstone a precious or semiprecious stone, especially one cut, polished, and used in a piece of jewelry.
Ore a naturally occurring solid material from which a metal or valuable mineral can be profitably extracted.
Ore Deposit is an accumulation of ore.
Cementation the binding together of particles or other things by cement
Lithification is the process in which sediments compact under pressure, expel connate fluids, and gradually become solid rock.
Organic of, relating to, or derived from living matter.
Foliation the process of being split into thin sheets or laminae.
