Depending on the substance which is fractured, a fracture reduces strength or inhibits transmission of light . asperity is the measure of how resistant unshakable matter is to various kinds of stable shape change when a force is applied proper(postnominal) Gravity is the ratio of the density (mass of a unit volume) of a subst ance to the density of a given reference s! ecular Streak the color left by a mineral dragged across a rough surface Associated Minerals are minerals that are found in a small quantity with a more major mineral at a locality. glorious Localities Excellent specimens of diverging groups of white prismatic crystals Other material Properties and Characteristics: Fluorescence the emission of light by a substance...If you want to entreat a full essay, order it on our website: OrderEssay.net
