Is color the best physical characteristic for mineral identification?
Specimen color is the least reliable method of mineral identification. Better characteristics are streak, density, and crystal structure.
What is the most unreliable characteristic of a mineral?
Color is often considered the most unreliable characteristic of a mineral because it can vary widely even within the same mineral species. Factors such as impurities, alteration, and external conditions can all influence the color of a mineral, leading to inconsistencies in color as a reliable identification feature.
A sometimes misleading characteristic when identifying a mineral?
color
Which rock characteristic below is is the color of powdered mineral?
the answer is STREAK
What characteristic is used to determine the color of a mineral's powder?
The characteristic used to determine the color of a mineral's powder is known as its "streak color." This is achieved by scratching the mineral against an unglazed porcelain plate to observe the color of the powdered residue left behind. Streak color can sometimes differ from the visible color of the mineral.
Which mineral characteristic is NOT determined by the way the atoms within a mineral are arranged?
color, streak and age
Color of powered mineral?
It's referred to as the streak, the color of which is used as an identifying characteristic of minerals.
What is a characteristic that depends on which parts of the visible light spectrum are reflected from a mineral?
Color is a characteristic that depends on which parts of the visible light spectrum are reflected from a mineral. Different minerals absorb and reflect certain wavelengths of light, resulting in the colors we observe.
What is the least reliable physical property for mineral identification?
Color is the least reliable physical property for mineral identification because many minerals can have the same color but different properties.
Is color a characteristic property of an element?
No, color is not a characteristic property of an element. The color of an element can vary based on its form or the conditions it's exposed to, but it is not a defining characteristic of the element itself.
Why is streak color more reliable thn mineral color as an identifying characteristic?
Streak color is more reliable than mineral color because it reflects the true color of a mineral in its powdered form, which eliminates the influence of surface impurities and variations. Mineral color can vary widely due to factors like weathering, impurities, and different crystal structures, leading to potential misidentification. In contrast, streak color remains consistent for a given mineral, making it a more dependable characteristic for identification in mineralogy.
Which characteristic is most responsible for the color of different types of rocks?
The mineral constituents of rocks are the major source of their color.
