| Question | Answer |
|---|---|
| naturally occurring | made from nature |
| inorganic | made from non-living plants or organisums |
| soild | an object that has a definite shape and volume |
| definite chemical formula | when a mineral has to have a certin mineral and a certin amount of that mineral to be the same mineral |
| crystal structure | a crystal is a solid, goemetric form that result from a repeating pattern of atoms or molecules |
| color | the hue of a mineral (not a good way to identifiy a mineral) |
| streak | the color of a minerals powder |
| luster | the way a mineral reflects light |
| clevage | a way that a mineral breaks, smooth and have flat surfaces |
| fracture | a way that a mineral breaks, in no form or pattern, unevenly |
| density | the amount of matter in a given amount of space |
| hardness | the minerals resistence to being scratched |
| special properties | special properties (naturally magnetic, double image...etc...) |
| alloy | a solid mixture of 2 or more elements, at least 1 is a metal |
| ore | a rock that contains a metalor other useful mineral that can be sold for profit |
| what are the 3 types of mines? | open pit, strip, and shaft mines |
| open pit mine | miner use giant earth moving equitment to dig a tremendous pit and remove ore deposits |
| strip mine | earthmoving equipment scraps away soil to expose ore |
| shaft mine | often have a network of tunnels that extend deep into the groud following the viens of ores |
| what scale is used to rate the hardness of a mineral? | the mohs hardness scale |
| what is the softest mineral on the mohs hardnesas scale? what is its rating? | talc with a rating of 1 |
| what is the hardest mineral on the mohs hardness scale and what is its rating? | diamond with a rating of 10 |
| what are the 3 ways a MINERAL CAN BE FORMED? | by metamorphism, from solutions, and when magma and lava cool |
| what are the 3 different types of rock? | igneous rock, metamorphic rock, and sedimentary rock |
| how does an igneous rock form and what are the 2 subgroups? | when magma and lava cool and the 2 subgroups are extrusive and intrusive |
| how does metamorphic rock form and what are the subgroups? | it forms through heat and pressure, and the 2 groups and non-foliated(without parallel bands) and foliated( with parallel bands) |
| how does sedimentary rock form and what are the subgroups? | sedimantary rock goes through the processes of weathering, erosion, deposition, cementation, and compaction and the subgrougs are clastic, chemical and organic |
| organic sedimentary rock | sedimentary rock that formed from living or once living things |
| clastic sedimentary rock | formed when sediments buried compacted and cemented together by calcite or quartz |
| chemical sedimentary rock | formed when when water, usually seawater, evaporates |
| what are the processes in which ignous rock forms? | melting and cooling |
| what are the processes in which metamorphic rock forms? | heat presure and chemical reaction |
| what are the processes in which sedimentary rock forms? | weathering erosion deposition compaction cementation |
