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
Identifying the Problem
The table includes hardness and streak color for several minerals. How can you use these data to distinguish minerals? ____________________________________________________________________________________________
