Because each mineral will have properties that when considered together will uniquely identify it. For example, I have two crystals, both are very hard, optically transparent, chemically resistant to acid and alkali, mechanically inelastic, brittle, electrical insulators, non-magnetic etc etc etc. One is green and the other is clear. One of them might be olivine and the other might be quartz due to their color alone. Other properties, if measured, could make me more certain, but I have a good guess already. The more properties you measure,the more possibilities you can eliminate until you have only one possibility to consider. The green one might be an emerald and the clear one could be a diamond. What property do I still have to measure? Try refractive index? That would clinch it.
The seven characteristics used to identify minerals are color, streak, luster, hardness, cleavage, fracture, and specific gravity. These properties can help differentiate one mineral from another based on their unique physical and chemical properties.
Streak is not used to identify every mineral because some minerals have the same color streak, making it unreliable for differentiation. Additionally, some minerals are too hard to leave a streak, while others may create a variable streak due to impurities. As a result, streak is just one of several properties used to identify minerals.
Three common methods used to identify bacteria include Gram staining, biochemical tests, and molecular techniques such as polymerase chain reaction (PCR) or sequencing of the bacterial genome. These methods help to determine the characteristics of the bacteria, such as cell wall composition, metabolic characteristics, and genetic makeup, which aid in identification.
Specific gravity is a useful property to help identify minerals because it can provide insights into the mineral's density compared to water. By measuring the specific gravity of a mineral, geologists can narrow down potential mineral identifications based on known specific gravity values for different minerals. However, it is not always a definitive method for mineral identification and is usually used in conjunction with other tests and observations.
Minerals can change color based on small impurities.

The eight characteristics used to classify minerals are color, streak, luster, cleavage, fracture, hardness, specific gravity, and crystal form. These properties help geologists identify and differentiate between different types of minerals based on their physical and chemical characteristics.
The seven characteristics used to identify minerals are color, streak, luster, hardness, cleavage, fracture, and specific gravity. These properties can help differentiate one mineral from another based on their unique physical and chemical properties.
Color, luster (appearance of light reflecting off the surface), streak (color of a mineral in powdered form), hardness (ability to resist scratching), cleavage (tendency to break along flat surfaces), and specific gravity (density compared to water) are physical characteristics used to identify minerals.
Minerals can be recognized and distinguished based on physical properties such as color, luster, hardness, cleavage or fracture, specific gravity, and crystal habit. These properties can help in identifying different minerals as they each have unique characteristics that can be used for classification.
yes it is

Magnetism can be used to identify minerals by observing their response to a magnetic field. Some minerals are attracted to a magnet, some are repelled, and some show no response at all. By studying these behaviors, geologists can help to identify certain minerals based on their magnetic properties.
Luster and composition are two characteristics used to classify minerals.
The scale used to identify minerals is called the Mohs scale of mineral hardness. It ranks minerals from 1 (softest) to 10 (hardest) based on their ability to scratch or be scratched by other minerals.
I think its Specific Gravity :)
When minerals are hit with a hammer, they may break, fracture, or shatter, depending on their hardness and crystal structure. Some minerals will form cleavage along specific planes, while others will show irregular fractures. This property can be used to help identify minerals based on their physical characteristics.
