Crystal | Solid in which atoms are arranged in repeating patterns |
Fracture | When a mineral breaks into pieces with arclike rough or jagged edges |
Gem | Rare precious highly prized mineral that can be cut polished and used for jewelry |
Hardness | measure of how easily a mineral can be scratched which is determined by the arrangement of a minerals atoms |
Luster | The way that a mineral reflects light from its surface two types of metallic and nonmetallic |
Mineral | Naturally occurring inorganic solid with a specific chemical composition and a definite crystalline structure |
Silicate | Mineral that contains silicon oxygen and usually one or more other elements |
Specific gravity | Ratio of the mass of a substance to the mass of an equal volume of h2O at 4 Celsius |
Streak | Color a mineral leaves when it is rubbed across an unglazed porcelain plate or when it is broken up and powdered |
Tetrahedron | A geometric solid having four sides that are equilateral triangle |

Bowenâs reaction series | Sequential what is Google group bunch pattern in which minerals crystallize from Cooling magma |
Extrusive rock | Fine grained hurt me as rock that is formed one more on Rockwells quickly and solidifies on earths surface |
Fractional crystallization | Processes in which different minerals crystallize from magma at different temperatures are moving elements from magma |
Granitic rock | White colored interested igneous rock that has high silica content |
Igneous rock | Intrusive or extras of rock forms from the cooling and crystallization of magma or lava |
Intrusive rock | coarse grained igneous rock that is formed when molten rock cools slowly and solidifies inside earths crust |
Kimberlite | Rare ultramafic rock that can contain diamonds and other minerals formed on the under very high pressures |
Lava | Magma that flows out onto earths surface |
Partial melting | Process in which different minerals melt into magma different temperatures changing its composition |

Porphyritic texture | Rock texture characterized Buy large well form crystals surrounded by final green crystals of the same or different mineral |
Texture | Massage shaved and distribution of the crystals or dreams that make up a rock |
Vesicular texture | Characterized by containing vesicles or holes formed by gas bubble |
