crystallization | The process by which crystals are formed. |
cubic | A crystal form characterized by three equal axes at right anglr\es to each other. |
conglomerate | The conversion of a substance from a liquid to a gaseous. |
fossil | A solid substance in which the particles are arranged in an orderly,repeatable pattern |
hardness | The resistance of the surface of a mineral to scraching by another substance. |

luster | The way a mineral reflects light. |
magma | the hot, liquid rock within the Earths crust. |
metallic luster | describes a mineral that is usually dark in color,is always opaque, even on its thin edges, and shines like polished metal. |
metamorphic | A type of rock formed when igneous, sedimentary, or even other metamorphic rocks are subjected to extreme heat and/or pressure deep below the Earth's surface. |
mineral | A naturally occurring , solid, inorganic substance with a definite chemical composting and usually |
Mohs scale of hardness | A scale of hardness used in mineralogy. |
monoclinic | Noting or pertaining to a system of crystallization in which the crystals have three unequal axes, with one oblique intersection. |
nonmetallic luster | Describes a mineral that is usually light colored and whose surface appears glassy, greasy, brilliant, pearly, silky, or dull. |

property | Any quality that serves to describe or define an object, material, or relationship. |
rock | A naturally occurring inorganic solid usually comprised of a mixture of different and other minerals |
sedimentary | a type of rock formed by the solidification of layers of sediments |
silicon | one of the most abundant elements on Earth; its electrical properties enable it to be used in electronic devices. |
