Many rocks can be, but some would require other tests to aid in identification.
Multiple attributes help geologists determine what sort of rock a particular sample is. The most notable are appearance, and color, reaction to different acids.
you can tell by looking in it and tell by the color that is in side of it. or you can ask someone that know allot about rocks
Describe how this rock sedimentary is formed
No, you cannot identify a mineral using only one characteristic. There are many that are the same color, for example, or the same hardness or with the same sort of streak.
but
In organic, with characteristic physical properties
A mineral crystal. Minerals form a crystalline structure.
Color, due to the effects of impurities, is the least reliable identifying mineral characteristic.
man-made
What is mineral oil and what are its physical properties and its formula
In organic, with characteristic physical properties
The same mineral can come in a variety of colors and different minerals can be the same color.
Specimen color is the least reliable method of mineral identification. Better characteristics are streak, density, and crystal structure.
A mineral crystal. Minerals form a crystalline structure.
The characteristic property of the mineral pyrite is sand it is very shiny
Color, due to the effects of impurities, is the least reliable identifying mineral characteristic.
rough, sharp
Hardness, which is measured by the Mohs Scale, which goes from 1, very soft, like talc, to 10, very hard, like diamond.
it is hardness
The mineral is hematite.
According to Wikipedia's definition of mineral, no. "A mineral is a naturally occurring solid chemical substance formed through biogeochemical processes, having characteristic chemical composition, highly ordered atomic structure, and specific physical properties."
An accessory mineral is a mineral present in small amounts in a rock, but not considered to be characteristic of the rock.
