6. what is a streak test in mineral identification? determining the color of a minerals powder form measuring the reflectiveness of a mineral assessing the minerals hardness testing how a mineral breaks
Answer
Brief Explanations:
A streak test in mineral identification involves rubbing a mineral across an unglazed porcelain plate to see the color of the powder (streak) it leaves behind. This powder color can be more consistent and diagnostic than the mineral's surface color. Measuring reflectiveness is related to luster, assessing hardness is done with Mohs scale, and testing breakage is about cleavage or fracture.
