To quickly identify a mineral sample, geologists use:

For the answer to the question above, the geologists must look closely at the physical properties of a mineral. These properties can include the color, streak, hardness, cleavage, specific gravity, crystal form, and others factors.

Explanation:
Even geologists will have a tough time distinctive minerals. There area unit over four,000 better-known minerals, and close to 80-100 new one's area unit discovered annually. Of these, solely some hundred are thought of common.

To help with identification, geologists should look closely at the physical properties of a mineral. These properties will include color, streak, hardness, cleavage, relative density, crystal type, and others. By observing them one can predict properties.
