RESPONSE:
For a material to be classified as a mineral, there are four requirements that it must have. The
requirements state that a substance must be a naturally occurring solid, formed by inorganic
processes, with a characteristic crystal structure, and a specific chemical composition. Each of
these requirements must be present in order to be classified as a mineral. The best ways to
differentiate between minerals is to study the luster, crystal form and habit, hardness, cleavage,
density, and color and streak. Each characteristic is essential for properly identifying minerals.
Luster describes how a mineral looks in the light, such as if it is shiny or dull. The crystal form
and habit of a mineral are the descriptions and shapes which also show what the mineral will
form in the future. Symmetry is also shown on the crystal forms, which is also the crystal form
and habit. Hardness is identified by the strength of the bonds and crystal structure. If a mineral
can endure scratches or other types of abrasion, its hardness level is high. If not, the hardness
is low. Cleavage refers to the shapes of the mineral after it has been broken. If the shapes and
structure of the mineral is rough and uneven, it is a fracture. If the mineral has parallel planes
and is smooth, it has cleavage. The color and streak of a mineral is not the best way to identify
a mineral, however it may be used for some identification. Chemical composition plays a factor
in the color and streak as some elements create strong color effects. Lastly, density how light or
heavy a mineral is. Minerals that have a high density have closely packed atoms, and minerals
that have low density have less closely packed atoms.
Rocks and minerals are not the same. Rocks are forms and structures of minerals that are
formed naturally and are composed together to form themselves. Minerals are naturally formed
chemical compounds that include atoms that form a certain structure. Minerals have distinct
properties to make it simple to identify one from another.
