| a type of cairn (rock piles left by hikers) | Inukshuk |
| on going | Process |
| made of one or more minerals, glass, organic matter | Rock |
| formed by cooling and hardening of molten material | Igneous rock |
| molten material from a volcano found on the surface | Lava |
| igneous rocks formed when magma cools quickly on the surface (exterior) | Extrusive |
| igneous rock formed when magma cools slowly below the surface (inside) | Intrusive |
| light colored igneous rock, rich in silicon and oxygen | Granitic |
| dark colored igneous rock, rich in iron and magnesium | Basaltic |
| the process by which Earth materials form and change | Rock Process |
| Coarse-grained rocks where individual grains can be seen with naked eye have _____ | phaneritic texture |
| fine-grained rocks whose grains are not visible with the unaided eye have ______- | aphanitic texture |
| rocks that contain large minerals surrounded by smaller minerals have _____ | porphyritic texture |
| During the cooling of magma, different minerals will ________ at different temperatures | crystallize |
| The relationship between temperature and crystallization is called | Bowen's reaction series |
| minerals and rocks are made of _________ materials | different |
| granite is made of a _______ of materials | mixture |
| basaltic rocks are _______ colored | dark |
| quick cooling of lava results in ________ grains | fine |
| cooling magma results in _______ grains | large |
| banding occurs in ________ rocks | foliated |
| Two types of metamorphic rocks are | foliated or nonfoliated |
| rocks that change due to temperature and pressure increases or changes in composition | metamorphic |
| radioactivity, heat and pressure can produce | magma |
| the type of metamorphic rock produced depends on | heat, pressure and composition |
| _________ can be used to produce electricity | coal |
| granite has larger mineral grains than | rhyolite, andesite and basalt |
| mixing _________ with waste coal changes acidic waste to alkaline ash | limestone |
| waste coal is used to produce | electrical and thermal energy |
| granite is a mixture of minerals such as: | mica, feldspar, hornblende and quartz |
| in the process of cogeneration, | both electrical and thermal energy are used |
