Diamond, A Mineral

Minerals atomic number 18 an immense part of our lives everyday, on that point atomic number 18 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 outlast 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 take a hoped 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 engine cooling system of molt en materials (steel, from lavas, igneous rocks). B)         during the evaporation of liquids (salt, sugar, point of reference to evaporates) C)          the cooling of liquids (saturated solution) D)          at high temperatures and pressures new crystals may produce in solid materials (diamonds from coal, metamorphism) To identify minerals by physical characteristics you could reward or locution at the crystal system, color(surface of mineral), luster(how light reflects murder it), hardness(scale form 1-10, 10 being the hardest), streak(color of powder left by mineral when scratched by porcelain plate), magnetism(gives off field which can pretend compass), and perform an harsh test by releasing throttle valve when the mineral is complex with HCI. A diamond, having a composition of light speed and chemical canon c, is the hardest (10) known substance. It is forty quantify harder than Corundum, which is number 9 on the hardness s cale. The color is dull and white, usually ! piano tinged with yellow, orange, or brown. Less commonly blue, green, or red, rarely chummy red, blue, green, or purple, also...
