GEOL 1100 Lecture Notes - Lecture 2: Magnesium, Radioactive Decay, Hydrosphere
Document Summary
Earth"s 4 spheres : lithosphere, hydrosphere, atmosphere, biosphere. A mineral has 5 key components : solid, inorganic (not living, natural (nature can make it, specific chemical composition, crystal-like patterns or structures, 14 types of ice minerals. Is ice a mineral? yes, it checks off on the 5 key components list. Are the 2 key factors to make a crystal structure: silicon, oxygen, aluminum, magnesium, iron, sodium, potassium, calcium (si & o are the 2 most abundant of the list, si & o = foundation bonding pair. ) most commonly used first is mg and fe. When magma starts to cool/slowing down the bonds become more stable: minerals are made when bonds become stable, exception: mg,fe,ca love to bond when temperature is high. * in a single tetrahedral, you can not add calcium because it is too heavy : ca is too big to fit in the structure of one tetrahedral, olivine does not get to use ca i.
