| 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 |
| siliacates | a salt in which the anion contains both silicon and oxygen, |
| cleavage | a sharp division |
| crystallazation | mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs |
| inorganic rock | a rock that doesn't have living organism matter |
| metamorphic rock | 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 (an event or situation, typically one that is bad or undesirable) to happen suddenly, unexpectedly, or prematurely |
| 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 |
| sedimentary rock | types of rock that are formed by the deposition of material at the Earth's surface and within bodies of water |
