1: CAMPING | What a beautiful view! | AUSTIN NELSON & JOSH MURRAY | 6th period Earth systems
2: Igneous rock | Pumice | Obsidian
3: EXAMPLES: obsidian, pumice, granite. | Granite | Igneous rock is formed from the cooling of magma or lava | Also it can be transformed into metamorphic rock by heat and pressure
4: Sandstone | Shale | Sedimentary | Conglomerate
5: sedimentary rocks is formed by compression of eroded rock in bodies of water layer by layer and eventually forms a rock | Examples: sandstone, shale, conglomerate | Sedimentary rock is transformed into metamorphic rock, which is caused by the pressure exerted on it by the earths crust. It is also transformed into igneous rock, which is caused by tons and tons of pressure and usually heat either external or created by the pressure exerted on the rocks.
6: METAMORPHIC MARBLE SLATE HORNFELS
7: Metamorphic rock is formed by the melting of sedimentary and/or igneous rock. | Metamorphic rock which is exposed to increasing heat and pressure from various sources can eventually melt, when melted it then solidifies, and becomes igneous rock. Can be transformed through erosion, deposition, cementation, melting, cooling | EXAMPLES: marble, slate, hornfels
8: SILICATE | CHEMICAL COMPOSITION: silicon+oxygen STRUCTURE: crystalline structure(6 kinds): isolated tetrahedron, ring, chain, double chain, sheet, framework EXAMPLES: quartz, micas, olivines
9: MINERALS MAJOR CHARACTERISTICS: crystalline structure, cleavage, hardness, density, luster, streak, color SPECIAL FEATURES: fluorescence, magnetism, taste
10: NON-SILICATE | CHEMICAL COMPOSITON: anything other than silicon+oxygen STRUCTURE: crystalline structure(5 kinds): oxides, sulfides, sulfates, halides, and carbonates EXAMPLES: gold, graphite, diamond
11: MINERALS | MAJOR CHARACTERISTICS: crystalline structure, cleavage, hardness, density, luster, streak, color SPECIAL FEATURES: fluorescence, magnetism, taste
12: EXAMPLES: synthetic ruby, synthetic diamond, synthetic emerald | SOLIDIFICATION OF A MELT
13: HOW THIS OCCURS: Cooling reflects the removal or dispersion of that heat away from the melt, allowing the atoms to move less freely, to gather closer together, and eventually to reform chemical bonds | HOW SCIENTISTS USE PROCESS IN THE LAB TO GROW SYNTHETIC MINERALS: melted substance are mixed together then cooled to form synthetic minerals.
14: PRECIPITATION OF A SOLID HOW SCIENTISTS USE PROCESS IN THE LAB TO GROW SYNTHETIC MINERALS: mix and substance and a solution to cause a reaction that forms a solid.
15: HOW THIS OCCURS: a substance is put into a solution and a reaction occurs which cause a solid to form from the mixture EXAMPLES: salt, sugar, malachite
16: SOLID-STATE DIFFUSION
17: HOW THIS OCCURS: the movement and transport of atoms occurs because of the presence of defects in solids EXAMPLES: synthetic sapphire, synthetic topaz, synthetic quartz
