A hypothesis for mineral identification could be that specific physical and chemical properties, such as hardness, color, luster, and crystal structure, can be used to accurately classify minerals into distinct categories. For example, "If a mineral exhibits a Mohs hardness of 7, a vitreous luster, and a cubic crystal habit, then it is likely to be identified as quartz." This hypothesis can be tested by examining various minerals and comparing their properties to known standards.
Color is the least reliable of a mineral's characteristics used in its identification.
Color is the least reliable physical property for mineral identification because many minerals can have the same color but different properties.
Sample E on the Mineral Identification Gizmo is Quartz. It has a hardness of 7 on the Mohs scale, a white streak, and breaks with a conchoidal fracture.
I'm sorry, but I do not have access to specific tools or external platforms like Gizmo, so I cannot provide the mineral type for Sample H. However, mineral identification typically involves assessing properties such as color, hardness, luster, and streak. If you can provide more details about Sample H, I would be glad to help with the identification process.
The color of a mineral can be influenced by various factors, such as impurities, weathering, and the presence of trace elements, making it inconsistent. Different minerals can also exhibit the same color, leading to confusion in identification. Additionally, some minerals may appear in multiple colors, further complicating their identification based solely on color. Therefore, relying on color alone can be misleading, and other tests are necessary for accurate mineral identification.
Sample B on the Mineral Identification Gizmo is calcite.
The powder indicates the true color of the mineral and is an aid in mineral identification. That can also be called a streak.
Specimen color is the least reliable method of mineral identification. Better characteristics are streak, density, and crystal structure.

The mineral identification flow chart outlines a process for determining the composition of a mineral sample by first identifying its physical properties such as color, luster, hardness, and cleavage. Based on these properties, the flow chart guides the user to perform specific tests, such as acid reaction or streak test, to further narrow down the possible mineral compositions. Finally, the flow chart leads to the identification of the mineral based on its unique combination of properties.
Diamond is often considered the hardest mineral in identification keys, scoring a perfect 10 on the Mohs scale of mineral hardness. Its exceptional hardness makes diamond a useful reference point for comparing the hardness of other minerals.
Color is generally considered the least reliable mineral identification property because many minerals can have a variety of colors due to impurities or variations in chemical composition.
Hardness and streak color are very important. The color of the mineral helps some, as well.
