** Mineral **- a naturally occurring inorganic solid formed through geolical processes that has a characteristic chemical composition, a highly ordered atomic structure, and specific physical properties.

~ **Minerals** are formed by natural processes. ~ ** Minerals ** are not alive and never were alive. ~** Minerals ** can come from magma or solutions such as water or any other type of liquid.

__ **Characteristics of a Mineral ** __ Characteristics of a **mineral** are traits given to a ** mineral ** that help identify that ** mineral **. Such charcteristics include color, luster, streak, fracture, hardness, and cleavage.

A ** mineral ** is having a specific chemical composition and physical structure.A native ** mineral ** is a

 * **__ Color __-** The recognition of colors in **minerals** goes back to our pre-historic ancestors who used charcoal and iron oxides to color cave paintings which still retain their original intensity. Visible spectrum: ** Red, Orange, Yellow, Green, Blue, Indigo, Violet **
 * **__ Luster __ -** the way a ** mineral ** reflects light from its surface, there are two types metallic and non metallic
 * **__ Transparency (or diaphaneity) __-** describes if you can see through something or not
 * **__ Crystal Systems __-** is a class of point groups.
 * **__ Technical Crystal Habits __** - is a description of the shapes and aggregates that a certain ** mineral ** is likely to
 * **__ Descriptive Crystal Habits __-** terms are more descriptive than the technical crystallographic terms and are therefore easier to understand
 * **__ Twinning __-** Twin Crystals are crystals of the same ** mineral ** species that grow attached to each other at certain angles.
 * **__ Cleavage __-** a ** mineral ** that splits relatively easily and evenly along one or more flat planes is said to have cleavages**.**
 * **__ Fracture __-** is when a ** mineral ** breaks, but the surface is not regular, does not show cleavage
 * **__ Hardness __-** a measure of how easily a ** mineral ** can be scratched. Based on the Mohs scale of hardness which compares the hardness of one ** mineral ** to ten easily recognized ** minerals **.
 * **__ Specific Gravity __-** how heavy something feels when compared to what you would expect,

 * <span style="font-family: Tahoma,Geneva,sans-serif;">**__ Notable Localities __-** The place or region in which a rock, series of rock, or formation is typically exposed.

<span style="font-family: Tahoma,Geneva,sans-serif;">**__Special properties Of Minerals __ ~__ Streak __-**The color of a **mineral** when it is powdered is called the ** streak ** of the **mineral.... the streak of a mineral helps us find the the type of mineral .. you can find the streak by taking the mineral and striking it against a streak plate and the streak color helps us find out what type of mineral it is** ​~__ Hardness __-a measure of how easily a ** mineral ** can be scratched. Based on the Mohs scale of hardness which compares the hardness of one ** mineral ** to ten easily recognized ** minerals **. ~__ Color __-**The recognition of colors in **minerals** goes back to our pre-historic ancestors who used charcoal and iron oxides to color cave paintings which still retain their original intensity.
 * ~__ Luster __-** word used to describe the way light reflects off of the surface of a ** mineral
 * ~__ Shape __-**The characteristic surface configuration of a thing; an outline or contour
