Characteristics of a Mineral
1. All minerals are made naturally by the
Earth.
Mineral Characteristics
2. Minerals are inorganic. They are not
made by and do not contain living or
once living things.
Mineral Characteristics
3. Minerals are always a solid.
YES!!!
Mineral Characteristics
4. Minerals have an orderly arrangement of
repeating atom patterns. (crystals)

5. Minerals have a definite chemical
composition. (a specific recipe)
For example,
diamonds are always
made of Carbon (C)
only.
Salt is always made
of Sodium and
Chloride (NaCl)
