Answer:

Luster, hardness , colour , clevage and magnetism

Step-by-step explanation:

1. Luster makes sure the light is reflected by the mineral.

2. On the 10-point Mohs scale, which is basically a scratch test, hardness is measured. Take an unidentified mineral and scrape it like a fingernail with an object of known hardness.

3. Zurite, for instance, is often a deep blue, and malachite is gray.

4. In minerals that appear to divide along one or more flat surfaces or planes, cleavage may be observed.

5. Magnetite, for instance, has a heavy pull that even weak magnets can draw. But there is only a poor attraction to other minerals, particularly chromite (a black oxide) and pyrrhotite (a bronze sulfide.)

Answer:

you can classify a mineral by its appearance and other properties. The presence of a mineral is defined by the color and luster, and the color of the powdered mineral is described by the band. Every mineral has a distinctive density. To compare the hardness of rocks, the Mohs Hardness Scale is used.
