Example:
Imagine trying to judge the flavor of a fruit just by looking at its skin. Just as a fruit may look one way on the outside but taste different on the inside, a mineral can appear a certain color in its natural form but show its true color when powdered. The concept of streak in mineralogy is like cutting into the fruit to taste its true flavor—it's about revealing the mineral's genuine color, which, like the flavor, cannot be accurately judged from the exterior alone.
Practice Version
Streak: A color of a mineral in its powdered form streak. Streak is the color left behind when a mineral is scratched across a porcelain tile, helping to identify it.
