Answer
Brief Explanations:
Minerals are naturally - occurring, inorganic solids with a definite chemical composition and a characteristic crystal structure. Cleavage is the tendency of a mineral to break along smooth, flat surfaces. Streak is the color of a mineral in its powdered form, usually obtained by rubbing it across an unglazed porcelain plate. Luster describes the way a mineral reflects light, such as metallic, non - metallic (e.g., vitreous, pearly). Color is the visible hue of the mineral, which can be affected by impurities. Hardness is a measure of a mineral's resistance to scratching, often determined using Mohs scale of hardness.
