2: Sedimentary Rock | -Formed in layers -Often found near water sources because the rock forms at the bottom of the surface when carried down streams, rivers, etc. -Sedimentary rock can be transformed by pressure, chemicals, and heat
3: Examples: - Limestone | -Sandstone | -Conglomerate
4: Igneous Rock | - Igneous Rock is formed when magma cools and hardens. - It can be transformed into metamorphic rock with chemicals, pressure and heat just like sedimentary.
5: Obsidian | Pumice | Scoria
6: Metamorphic Rock | How are they formed? Metamorphic rocks are rocks that have "morphed into another kind of rock. They were once sedimentary or igneous. The Rock is under tons and tons of pressure. Metamorphic rocks are rocks that were already either sedimentary or igneous rocks that have transformed to metamorphic
7: Gneiss | schist | Slate
8: Silicate | Silica tetrahedron, silica tetrahedron is an anionic species, which consists of a silicon atom covalently bound to four oxygen atoms. The silicon atom is in the geometric center of the tetrahedron and at each of the four points of the tetrahedron is an oxygen atom. The structure has an overall charge of negative four and is represented as SiO 4 4 .
9: Quarts | Feldspars | Mica
10: Non-Silicates | Every other mineral that does not have a silica tetrahedron in its structure is placed as a Non-Silicate. There are six sub groups of non-silicates they are; Carbonates, Oxides, Sulfides, Sulfates, Halides, and Native metals.
11: Gold | Graphite | Sulfur
12: Solidification of a melt | When the liquid (magma, lava, etc.) cools down and falls below a certain temperature and begins to solidify. This is like getting water and putting it in the freezer to make it a solid. Igneous rocks are examples too because the lava cools and hardens to make a rock.
13: Water being frozen | Obsidian | Scoria
14: Precipitation of a solid | Precipitation of other minerals does not have a solids melting and cooling and its structure is placed as a precipitated solid. They synthetically grow the minerals by injecting synthetics inside the rock that stimulates rapid growth.
16: Solid state diffusion | The method for introducing dopant atoms into semiconductors. In silicon solar cell processing starting substrates are typically uniformly doped with boron giving a p-type base. The n-type emitter layer is formed through phosphorous doping
