It often does not match the observable color of the specimen. Differences between streak and observable color can be due to inclusions, staining, refraction, impurities, or exposure to heat and radiation.

What are the properties used to identify minerals?

luster streak shape density color (not always reliable tho mulltiple types of minerals can have the same color) odor tenacity reaction to acid cleavage magnetism electrical properties


Why is color not a reliable physical characteristics when indentify a mineral?

Two different minerals can be the same color or two of the same minerals can be different colors.


What physical property is is unreliable as an identification clue for minerals?

Color is unreliable as an identification clue for minerals because different minerals can have the same color and the same mineral can exhibit different colors due to impurities.


Why is the color of the mineral not a reliable test for the identity of the minerals?

Because many different minerals may look the same, Like quartz and diamond, they are the same color, clear, but are very different minerals.

What is the problem with using only color to identify a mineral Give an example of a mineral that demonstrates your answer?

The color of many minerals is highly variable. Many minerals are found in many different colors. Eg. while malachite is always green, and sulfur always yellow, quartz can come in shades of purple, green, blue, red, yellow, brown, pink, etc., and tourmaline, garnet, calcite, and fluorite are equally color variable.


What is the least reliable physical property for identifying minerals?

Color is the least reliable physical property for identifying minerals because many minerals can have the same color but different compositions.


Why is the color of mineral not a reliable test test for the identity of the mineral?

The color of a mineral can vary depending on impurities present in the crystal structure. So, two minerals of the same color may not necessarily be the same mineral. Therefore, relying solely on color as a identification test can lead to misidentification of minerals.


Why is color often an unreliable property in identifying minerals?

Color can vary within the same mineral due to impurities or environmental factors. Additionally, many minerals come in a variety of colors, making it difficult to identify them based on color alone. Therefore, color is often not a definitive property for identifying minerals.


When a minerals color is changed by weathering its streak also changes true or false?

False. No matter what happens to the mineral, the streak will always remain the same.
