A geologist working in a national park finds a mineral. He is carrying a kit that contains a penny, a hand lens, a piece of tile, a geologic hammer, and a jackknife. Describe how the geologist can use items to determine some of the mineral's characteristics?
Help............. an fast please
Penny for hardness. Hand lens for luster. Tile to get powder for color. Hammer to break and identify fractures. Pocket knife to see if brittle, flexible, or malleable.
((My hands hurt))
1st, Don't spam words. 2nd. Hope your hands are okay even if this is a late reply and thanks for the answers above. @Sliverstream

what would answer be
Sure, I can help you with that. To determine some of the mineral's characteristics, the geologist can use the items in his kit in the following ways:
1. Penny: The geologist can use the penny to perform a scratch test. By scratching the mineral's surface with the penny, he can assess the mineral's hardness. If the mineral scratches the penny, it has a hardness greater than 3. If the penny scratches the mineral, it has a hardness less than 3.
2. Hand lens: The hand lens can be used to closely examine the mineral's physical characteristics such as color, luster (how it reflects light), cleavage (how it breaks), and crystal structure. The geologist can observe these details to help identify the mineral.
3. Piece of tile: The geologist can use the tile to perform a streak test. By rubbing the mineral against the tile, it will leave a streak of powdered mineral. The color of the streak can provide information about the mineral, which may be different from its external color. This can help with mineral identification.
4. Geologic hammer: The geologist can use the geologic hammer to break off a small piece of the mineral from a larger sample. By examining the broken surface, he can observe the mineral's internal characteristics such as its texture, grain size, and any visible crystals. This information can also aid in identification.
5. Jackknife: The jackknife can be used to test the mineral's cleavage. The geologist can use the knife blade to try and split the mineral parallel to its crystal planes. If the mineral easily splits, it has good cleavage. If it resists splitting, it may have poor cleavage or fracture instead.
By combining the information gathered from these different tests and observations, the geologist can determine several characteristics of the mineral, which can help in its identification and classification.
