Hardness
Degree of resistance that opposes a mineral to be scratched by another.
Recistance
Ability to resist.
To identify a mineral we have to look at its color, lustre, brightness, shape and hardness.
To see the hardness we can use the scale of mohs

A man not make
Inorganic
This don´t come from living things
Solid
Not liquid and not gas
