| Question | Answer |
|---|---|
| Example of an extrusive igneous rock that floats | pumice |
| What forms in nature, is a solid, has a definite chemical make up and a crystal structure? | mineral |
| type or rock that forms when molten rock or lava cools | igneous rock |
| the process in which existing rock changed by heat and pressure | metamorphism |
| NC state rock | granite |
| What forms when an igneous rock cools slowly? | large crystals |
| materials like rock pieces, minerals, and plant remains that settle out of water or air | sediments |
| process by which natural forces break down rocks | weathering |
| a naturally forming solid made of one or more types of minerals | rock |
| speed of cooling of an extrusive igneous rock | fast |
| original rock that was changed into a new metamorphic rock | parent rock |
| extrusive igneous rock made of natural glass but no minerals | obsidian |
| What forms when an extrusive igneous rock cools fast? | little or no crystals |
| What happens to molten material to form an igneous rock? | cooling |
| Type of sedimentary rock made of plant remains but no minerals | coal |
| place where metamorphic rocks form | deep in earth |
| What happens for an existing rock to form a new igneous rock? | melting |
| Set of natural processes that form, change, break down, and reform rocks | rock cycle |
| rate of cooling of an igneous rock to form large crystals | slow |
| process of sediment getting picked up and moved from one place to another | erosion |
| type of rock where loose pieces of sediment get pressed and cemented together | sedimentary |
| most likely place to find igneous rocks | near volcano |
| rock that forms under intense heat and pressure and changes into new rock | metamorphic |
| type of igneous rock that cools from lava | extrusive |
| arrangement of minerals in a metamorphic rock that are in flat, parallel bands | foliation |
| place most likely to find sedimentary rocks | near bodies of flowing water |
| type of rock that forms large crystals | intrusive |
| inorganic solid material found in nature | mineral |
| usually made of 2 or more minerals. | rock |
| How many minerals have been identified? | 4,000+ |
| have solid materials arranged in a repeating pattern. They can have smooth surfaces, sharp edges, and points. | crystals |
| Common table salt is the mineral __________, and it is made of tiny cube crystals. | halite |
| breaking of a mineral, which is caused by weaknesses within the mineral's arrangement of atoms. | cleavage |
| This mineral can reflect light and split into thin sheets. | mica |
| when minerals break with rough, jagged edges (ex. quartz) | fracture |
| scratching a mineral sample across an unglazed white tile is a ______ test. | streak |
| When conducting a streak test, is the streak always the same color as the mineral? | No |
| how light reflects from a mineral's surface (ex. shiny, dull, pearly) | luster |
| This characteristic is determined by the Moh's scale. | hardness |
| classifies minerals from 1 to 10 | Moh's scale |
| a Moh's scale score of 1 means that the mineral is ________. | soft |
| a Moh's scale score of 10 means that the mineral is _______. | hard |
| minerals that are rare and valuable- they can be cut and polished and have no blemishes or cracks and have beautiful luster and or color. | gems |
| A mineral which contains something useful and sold for profit contains this. | ore |
| produced when melted rock cools (can be intrusive or extrusive) | igneous rocks |
| When volcanoes erupt in fissures, the lava cools very quickly and does not allow crystals to form. These types of rocks usually has a glassy and smooth appearance. | extrusive |
| These kinds of rocks are formed when magma cools slowly below the earths surface. Minerals in magma have time to produce large crystals. | intrusive |
| liquid rock below the surface of the earth | magma |
| liquid rock above the surface of the earth | lava |
| made when pieces of other rocks, plant, and animal matter, or dissolved minerals collect to form layers | sedimentary rocks |
| these form over millions of years from biomass (ex. coal and chalk and limestone, which is made from fossils of tiny animals and algae) | biochemical rocks |
| old rock that changes by heat or pressure, and changes into new hard, dense rock. (recycled) | metamorphic rock |
| metamorphic rock that has bands of minerals | foliated |
| metamorphic rocks that have no distinct layers | non-foliated |
| the cutest, most clever, and witty girl in the whole wide world (or at least in Youngsville...) Hint: She has a high shiny luster and a cleavage on her bottom. | Gabrielle BK Valentine |
| produced when melted rock cools (and can be intrusive or extrusive.) | |
| the parent rock who helps her daughter study millions of science words, braids her hair, and cooks the best soup, and she broke off into a smaller, equally as clever, fashionable, and sassy daughter rock | Nikki Valentine |
