Answer to Question 1

Luster describes how mineral surfaces reflect light. Crystal faces are flat, smooth surfaces on mineral exteriors with regular geometric forms. Density is the measure of the mass of a material divided by its volume. Hardness is the resistance to scratching on a smooth surface. Cleavage describes planes along which a mineral breaks and the shape of the resulting fragments. Streak is the color of the residue remaining from scratching a mineral on a non-glazed porcelain plate. Color results from the interaction of light with the mineral.
