Minerals
| Term | Definition |
|---|---|
| naturally occuring | Created by nature. |
| inorganic | Cannot be created using any living thing, only NON-living. |
| solid | Minerals have a definite volume, and shape |
| crystal structure | particles of a mineral lines up in a pattern over and over again |
| define chemical composition | A mineral has definite chemical make-up of certain elements. |
| mohs hardness scale | Identifies hardness from softest to hardest of ten minerals. |
| color | Easily observed physical property. |
| streak | The color of the minerals powder is easily observed |
| luster | Its reflection of light in the minerals surface. |
| density | How tightly packed the matter is in the mineral. |
| crystal system | The minerals actual polygon shape, example cube, or hexagon. |
| clevage | Mineral breaks along a flat surface, smooth break. |
| fracture | Mineral breaks in an irregular way, jagged and uneven. |
| Crystallization through melted materials | form from magma that cools inside the crust or lava that cools on the surface. Magma cools slowly creating large minerals, and lava cools quickly creating small minerals. |
| Minerals in Hot Water Solution | Magma heats water to very high temperatures, when the hot water cools the water and leaves the solution that creates the crystallization. |
| Minerals form when solutions evaporate. | minerals form when solutions evaporate |
| gemstones | Using minerals such as rubies and sapphires for jewelry |
| metals | Using minerals such as aluminum, iron, copper, and silver, to make other items we use or want. |
| other useful minerals | Example: talc= talcum powder |
| prospector | someone who looks for ore deposits. |
| mining | Where ore deposits are mined. |
| strip mines | Equipment scrapes away the earth's surface to find ores |
| open pit mines | Used when ores or on the earth's surface, but at least 100 meters down |
| types of mines | Strip mines Open Pit mines Shaft mines smelting |
| ores | a rock that contains metal or useful minerals |
| shaft mines | are deep in the earth’s surface following the veins of an ore. |
| smelting | The process that is used after the ore is removed from the mine and the metal is removed from the ore. |
| where minerals are found | Many rare and valuable minerals are found in or near volcanic activity, mountain building, and bodies of water |
| rocks | Make up the earth's crust, that are made of a mixture of minerals and other materials |
| classifying rocks | Texture: the look and feel of the rocks surface; the grain: what gives the rock its texture. 1. Grain size 2. Grain shape 3. Grain pattern 4. No visible grain |
| mineral composition | geologists use a microscope to observe the shape and size of the rock’s crystals. |
| origin | 1. Sedimentary: forms in layers 2. Igneous: forms from magma or lava 3. Metamorphic: formed deep underground |
| igneous rocks | formed from intense heat that comes from magma or lava. |
| extrusive rocks | igneous rocks formed from lava that erupted onto Earth's surface |
| intrusive rocks | igneous rocks formed from magma that hardens beneath Earth's surface. |
| texture | depends upon the size and shape of the crystals |
| Porphyritic texture | large crystals surrounded by small crystals, which form when magma cools in two stages. |
| use of Igneous rocks | Used because they are hard, dense, and durable |
| basalt | gravel |
| pumice | cleaning and polishing |
| types of rocks | Basalt: gravel Pumice: cleaning and polishing Perlite: soil mixes Obsidian: sharp tools Granite: building materials |
