Question | Answer |
natural resources | materials that are found on earth and are used by people |
renewable | something that is commonly found and used, can be used over and over again |
nonrenewable | harder to find, more valuable, worth more money, harder to get, might be older |
Crystal shape | the shape of the crystal
example: tetrahedron, cube, octahedron, and rhombohedron |
luster | how shinny an object is |
property | observations like the one you made con be used to identify different minerals |
transparency | property of weather an item can be seen through |
Octahedron | 8 sides and each side is a triangle |
fluorite | a non-living solid found naturally on earth it is made of calcium and fluorine atoms arranged in crystalline structure |
crystalline structure | specific set of atoms that are arranged in a repeating pattern, in the right environment, minerals form large crystals because they have this |
geologist | people who study rocks, minerals, and other non-living parts of the earth |
mineral | non-living materials that are found naturally on earth, normally hard, has structure |
rock | made of minerals, some of these minerals are harder to find, although others are very common and easy to find |
igneous | forms when magma cools |
magma | the heat/melted rocks that when this cools it turns into an igneous rock |
metamorphic | high heat and/or high pressure of the Earth |
sedimentary | sediments ( tiny rock pieces ) cementing together |
erosion | |
rock cycle | how one type of rock becomes another |
sediment | parts of rocks, shells, and dead organisms that have been worn down into small pieces, by the effects of wind and water |
trade off | something that you do that results in something else to happen; we bought a mined rock, but it costs more |
________________ rocks can contain fossils | sedimentary |
In __________________ rocks, you can see bands | metamorphic |
______________ rocks can be smooth or glassy or there are large visible crystals that can can be seen by the human eye | Igneous |
