Rocks and Minerals

QuestionAnswer
Cleavage The tendency of crystals, certain minerals, rocks, etc., to break in preferred directions so as to yield more or less smooth surfaces.
Crystal A clear, transparent mineral or glass resembling ice.
Fracture To break or crack.
Gem A cut and polished precious stone or pearl fine enough for use in jewelry.
Hardness The comparative ability of a substance to scratch or be scratched by another.
Luster The state or quality of shining by reflecting light; glitter, sparkle, sheen, or gloss.
Magma Molten material beneath or within the earth's crust, from which igneous rock is formed.
Mineral Any of a class of substances occurring in nature, usually comprising inorganic substances, as quartz or feldspar, of definite chemical composition and usually of definite crystal structure.
Ore A metal-bearing mineral or rock, or a native metal, that can be mined at a profit.
Silicate Any of the largest group of mineral compounds, as quartz, beryl, garnet, feldspar, mica, and various kinds of clay, consisting of SiO 2 or SiO 4 groupings and one or more metallic ions, with some forms containing hydrogen.
Specific Gravity The ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume.
Streak A portion or layer of something, distinguished by color or nature from the rest; a vein or stratum.
Basaltic The dark, dense igneous rock of a lava flow or minor intrusion, composed essentially of labradorite and pyroxene and often displaying a columnar structure.
Cementation The heating of two substances in contact in order to effect some change in one of them, especially, the formation of steel by heating iron in powdered charcoal.
Compaction The consolidation of sediments resulting from the weight of overlying deposits.
Extrusive Noting or pertaining to a class of igneous rocks that have been forced out in a molten or plastic condition upon the surface of the earth.
Foliated Consisting of thin and separable laminae.
Granitic A coarse-grained igneous rock composed chiefly of orthoclase and albite feldspars and of quartz, usually with lesser amounts of one or more other minerals, as mica, hornblende, or augite.
Igneous Rock Rocks formed by the cooling and solidifying of molten materials. Igneous rocks can form beneath the Earth's surface, or at its surface, as lava.
Intrusive Having been forced between preexisting rocks or rock layers while in a molten or plastic condition.
Lava The molten, fluid rock that issues from a volcano or volcanic vent.
Metamorphic Rock Rock that was once one form of rock but has changed to another under the influence of heat, pressure, or some other agent without passing through a liquid phase.
Non-Foliated
Rock Mineral matter of variable composition, consolidated or unconsolidated, assembled in masses or considerable quantities in nature, as by the action of heat or water.
Rock Cycle A continuous process by which rocks are created, changed from one form to another, destroyed, and then formed again.
Sediment Mineral or organic matter deposited by water, air, or ice.
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. Sedimentary rocks are often deposited in layers, and frequently contain fossils.
