Identifying Minerals
When it comes to identifying minerals, the best property for Caroline to use is the crystal structure. Crystal structure refers to the arrangement of atoms within a mineral, and different minerals have distinct crystal structures.
By examining the crystal structure, Caroline can compare it to known minerals and identify the mineral she is looking at.
Color, size, and weight can sometimes provide clues, but they are not reliable indicators for identifying minerals because many minerals can come in different colors, sizes, or weights.
Crystal structure is a more reliable and distinctive property to focus on.
