| what are strata? | layers in sedimentary rock |
| What kind of sedimentary rock can be can be cemented together by calcite or quartz? | clastic |
| what kind of sedimentary rock is made by fossils? | organic |
| What kind of sedimentary rock is made from dissolved minerals? | chemical |
| What is the process called in which sedimentary rocks are arranged in layers? | stratification |
| Process other than heat that causes metamorphism? | pressure |
| Process in which crystals in minerals change in size or composition | recrystallization |
| metamorphic rock in which mineral grains are not arranged in planes or bands | nonfoliated |
| a change in the shape of rock caused by force | deformation |
| metamorphic rock in which mineral grains are arranged in bands | foliated |
| result of large pieces of rock deep within the earths crust colliding | regional metamorphism |
| Which of the following is not true of metallic minerals | they do not conduct heat well |
| Which of the following is not a characteristic of a mineral | it is a living material |
| What are the two major groups of minerals | silicates and nonsilicates |
| The grouping silicates and nonsilicate minerals are based on | chemical composition |
| A silicate mineral must contain | silicon and oxygen |
| nonsilicate minerals include | native elements |
| In addition to reclamationa good way to reduce the enviromental effects of mining is to | recycle mineral products |
| The color of powder that a mineral leaves on a piece of white unglazed porcelain is called the minerals | streak |
| Which is not true of minerals | they are liquids |
| which of the following is not a class of nonsilicate minerals | micas |
| Halides when flourine, chlorine, iodine, or bromine combine with any of the following elements except | oxygen |
| What is a mineral deposit that is large enough and pure enough to be mined profitably called | ore |
| What kinds of mines are open pit mines and quarry mines | surface mines |
| what is the name for nonmetallic minerals that are valued for their beauty and rarity rather than their usefulness | gemstones |
| a repeating pattern of atoms ions or molecules in a mineral called | crystalline structure |
| an addition to silicon and oxygen, silicate minerals usually contain | other elements |
| halides and oxides are classes of | nonsilicate minerals |
| the potentially harmful effects of farming can be reduced by | reclamation of the land |
| which mineral is the most resistant to scratching | diamond |
| besides air and water what can change the color of a mineral | impurities |
| which of the following is not a type of luster | super metallic |
| on what type of surface does a fracture happen | curved |
| what is the softest mineral on the moh's hardness scale | talc |
| what is the color of a mineral in powdered form called | streak |
| A mineral must have a definite ? structure | crystalline |
| a minera l that is composed of only one element is called a | native element |
| Calcite and fluorite glow under ultraviolet light. This special property is called | Flourescence |
| MInerals such as halite and gypsum are left behind when ? evaporates | salt water |
| Minerals that contain uranium or radium can be detected by using a | geiger counter |
| more than 90 percent of earths crust is made up of | silicate minerals |
| One of the more common silicate minerals is ? which is the main component for most rocks on earth | feldspar |
| The way a mineral breaks depends on the arrangement of | atoms |
| When you say an object is shiny or dull you are describing its | luster |
| tear shaped bodies that form when magma moves upward | pegmatites |
| Environment in which groundwater works it way downward and is heated by magma and then reacts with minerals | hot-water solutions |
| Minerals formed when surface and groundwater carry dissolved materials into lakes and seas where they crystallize | limestones |
| Environment in which bodies of salt water dry up | evaporating salt water |
| Magma body that moes upward and cools before it reaches the surface, forming crystals | pluton |
| Where minerals form when rocks are altered by changes in pressures, temperature, or chemical makeup | metamorphic rocks |
| The process of returning land to its original condition | reclamation |
| The removal of minerals that are located at or near the surface of the earth | surface mining |
| A mineral deposit large enough and pure enough to be mined for profit | ore |
| A mineral that has a shiny surface, does not let light pass through, and is a good conductor of heat and electricity | metallic mineral |
| Naturally formed, inorganic solid with a definite crystalline structure | mineral |
| Tendency of some minerals to break along smooth, flat surfaces | cleavage |
| Natural mineral deposit that is large enough and pur enough to be mine for profit | ore |
| The ratio of mass to volume of a substance | density |
| The way a surface reflects light | luster |
| A material's resistance to being scratched | hardness |

| The special property of some minerals that can be detected by a Geiger counter | radioactivity |
| The special property that some minerals show when they come in contact with acids | chemical reaction |
| The special property of some minerals to attract iron | magnetism |
| The special property of calcite that causes a double image | optical property |
| open pits, quarries, and some coal mines | surface mines |
| used to make electronic equipment and aircraft parts | metallic minerals |
| large, tear-shaped bodies of magma where many gemstones can form | pegmatites |
| formed by changes in pressure, temperature, or chemical makeup | metamorphic rocks |
| used to make concrete and glass products | nonmetallic minerals |
| forms from slowly cooled magma that solidifies into a pluton | feldspar |
| forms in metamorphic rock | garnet |
| forms in tear-shaped pegmatites in hot fluid | topaz |
| forms when a body of salt water evaporates | gypsum |
| used to make fireworks | carbonates |
| used to make toothpaste | sulfates |
| used to make batteries | sulfides |
| copper and gold, for example | native elements |
| The smallest part of a element | atom |
| A substance made of two or more elements that have been joined by chemical means | compound |
| A solid whose atoms, ions, or molecules are arranged in a pattern | crystal |
| A substance that cannot be broken down into simpler substances by chemical means | element |
