Applying ScienceHow can you identify minerals?

You have learned that minerals are identified by their physical properties, such as streak, hardness, cleavage, and color. Use your knowledge of mineral properties and your ability to read a table to solve the following problems.

Properties of Minerals Mineral Hardness Streak Copper 2.5-3 Copper-redGalena 2.5 Dark gray

Gold 2.5-3 YellowHematite 5.5-6.5 Red to brownMagnetite 6-6.5 Black

Silver 2.5-3 Silver-white
