Diamond, A Mineral

Minerals atomic number 18 an immense part of our lives everyday, on that point argon everywhere 2200 different kinds of minerals, and 3,000 minerals are in the earths crust. Anything to be classified as a mineral they must be natural, have inorganic elements or compound, a clear chemic composition, a definite internal crystalline structure and detain but non least, fast(a). Of the nearly 2,000 minerals that have been named only 11 are among the more(prenominal) important rock- figureing minerals. Quartz, feldspar, mica, ferromagnesian minerals, calcite, gypsum, halite, igneous rocks (fire hurled rocks), extrusive or volcanic rocks, sedimentary rocks, and metamorphic rocks are the 11 among the important rock-forming minerals. They are the building blocks of rock, most of the rock-forming minerals are compounds of silicon and oxygen. Minerals can form under a variety of conditions, such as: A)         during the locomotive engine cooling system of molten mater ials (steel, from lavas, igneous rocks).

B)         during the evaporation of liquids (salt, sugar, adduce to evaporates) C)          the cooling of liquids (saturated solution) D)          at high temperatures and pressures new crystals may initiate in solid materials (diamonds from coal, metamorphism) To identify minerals by physical characteristics you could bump or locution at the crystal system, color(surface of mineral), luster(how light reflects out it), hardness(scale form 1-10, 10 being the hardest), streak(color of powder left by mineral when scratched by porcelai n plate), magnetism(gives off field which ca! n hazard compass), and perform an harsh test by releasing bollix up when the mineral is complex with HCI. A diamond, having a composition of one C and chemical canon c, is the hardest (10) known substance. It is forty generation harder than Corundum, which is number 9 on the hardness scale. The color is colorless and white, usually piano tinged with yellow, orange, or brown. Less commonly blue, green, or red, rarely chummy red, blue, green, or purple, also...
