Science Rocks Igne
Science Rocks- Igneous -Grade 8
| Question | Answer |
|---|---|
| The concept that the present is the key to the past. | Uniformitarianism |
| A group of minerals bound together. | Rock |
| Rocks formed by cooling and hardening of hot molten rock from inside the earth. | Igneous Rocks |
| Hot molten rock beneath the earth's surface. | Magma |
| Hot molten rock above the earth's surface. | Lava |
| Rocks fromed by hardening and cementing of layers of sediments. Made from: Rock fragments, plant and animal remains, and chemicals that form on lake and ocean bottoms. | Sedimentary Rocks |
| Rocks formed when already existing rocks are changed by heat and pressure into new kinds of rocks. | Metamorphic Rocks |
| Rocks formed from slowly cooling magma under the ground. | Intrusive/Plutonic Rocks |
| Rocks formed by quickly cooled lava on the earth's surface. | Extrusive/Volcanic Rocks |
| High in Silica, Aluminum, Sodium, Potassium, and Oxygen | Felsic Magma/Rocks |
| High in Iron, Magnesium, Manganese, and Nitrogen. | Mafic Magma/Rocks |
| Low in Iron, Magnesium, Manganese, and Nitrogen. | Felsic Magma/Rocks |
| Low in Silica, Potassium, and Sodium. | Mafic Magma/Rocks |
| Light colored rocks. | Felsic Magma/Rocks |
| Dark colored rocks. | Mafic Magma/Rocks |
| Magmas include Quartz, Potash Feldspar, Muscovite, and Plagiosclase. | Felsic Magma/Rocks |
| Magmas include Biotite, Horneblande, Augite, Labradorite, and Bytownite. | Mafic Magma/Rocks |
| Rocks include Granite, Syenite, Monzonite, Rhyolite, Trachytes, and Dacites. | Felsic Magma/Rocks |
| Rocks include Gabbro, Peridotie, Dunite, Basalt, and Limburgite. | Mafic Magma/Rocks |
| Slower, cooler, thicker magma. | Felsic Magma |
| Faster, hotter, thinner magma. | Mafic Magmas |
| Characteristic structure of a rock given by its size, shape, and arrangement of its mineral crystals. | Texture |
| Crystal size depends on _________________ and ________________. | the amount of time to grow in liquid magma. And the amount of dissolved gases in the magma. |
| Large mineral grains are formed when ____________________. | the magmas are trapped in the crust and harden slowy. |
| Rocks containing crystals surrounded by a fine grained mass. | Porphyry |
| Family that includes Quartz, Feldspar, Mica, Granite, and Obsidian and is made from felsic magmas. | Granite |
| Family that includes Olivine, Hornblende, and Biotite and is made from mafic magmas. | Gabbro |
| Family that has a color and composition in between Granite and Gabbro families and includes Pyroxenite, Dunite, and Peridotite. | Diorite |
