Answer:
Color, Most minerals have a distinctive color that can be used for identification. In opaque minerals, the color tends to be more consistent, so learning the colors associated with these minerals can be very helpful in identification.As with other tests, repetition usually pays off. Always try to use a sharp edge or point, rather than just dragging the mineral across the streak plate willy-nilly. While some soft minerals give a streak easily no matter how you drag them, others will not streak well unless you use a small surface area of the mineral to get the streak.Minerals are naturally occurring substances, with a definite chemical composition and ordered internal structure that is found beneath the earth’s surface.appearance makes it rather easy to distinguish from all other rocks. It is composed of the elements that make quartz, feldspar and iron/ magnesium minerals that have cooled so quickly that the minerals could not develop and crystallize. Colors vary from black to red, black & red (mahogany), gray, green, iridescent, snowflake.Some minerals, such as quartz, only form in one particular shape. Others, such as calcite, can be found in multiple shapes. Sometimes shape isn’t enough and you need to use other tests to help you identify a mineral. Hardness – How hard or soft a mineral is can tell you right away what mineral it could or could not be.Minerals that break this way do so because their atoms are arranged so that they break apart from each other along these planes. Mica is an example of a mineral that has cleavage.
