es(WK1&2)part II

• result of the way minerals absorb light; easily identified but not as reliable as streak.(PHYSICAL PROPERTIES OF MINERALS)

  Color
• color of the mineral in powder form; pulverizing minerals shows their true colors & is more visible.(PHYSICAL PROPERTIES OF MINERALS)

  Streak
• measure of minerals’ resistance to scratching; the harder it is, the greater the resistance from scratching.(PHYSICAL PROPERTIES OF MINERALS)

  Hardness
• describe how minerals break into pieces.- mineral fracture: breaks in a direction when there is no cleavage.(PHYSICAL PROPERTIES OF MINERALS)

  Cleavage and Fracture
• how minerals’ crystals are arranged; hand lens is a necessary tool to check this.(PHYSICAL PROPERTIES OF MINERALS)

  Crystalline Structure/Crystal Lattice
• extent of light that can pass through; degree of transparency may depend on thickness.(PHYSICAL PROPERTIES OF MINERALS)

  Transparency/Diaphaneity
• ability of a mineral to attract or repel other minerals.(PHYSICAL PROPERTIES OF MINERALS)

  Magnetism
• level of resistance or reaction to stress; can tell if brittle, malleable, elastic, etc.(PHYSICAL PROPERTIES OF MINERALS)

  Tenacity
• reaction to light; determine how brilliant or dull the mineral is.(PHYSICAL PROPERTIES OF MINERALS)

  Luster
• distinct smell released from a chemical reaction when subjected to water, heat, air, friction.(PHYSICAL PROPERTIES OF MINERALS)

  Odor
• measures density; how heavy a mineral is by its weight to the water.(PHYSICAL PROPERTIES OF MINERALS)

  Specific Gravity
