Review Minerals-8

I used this piece of calcite to scratch this penny. Then I used the penny to scratch the piece of calcite. What does that tell us?

  1. It tells us that I did the test wrong.

    No. The test was done correctly.
  2. It tells us that they both have the same hardness.

    Yes! You test the hardness of a mineral by testing to see what will scratch it. If two substances scratch each other, they have the same hardness.
  3. It tells us that calcite is not a mineral.

    No. Scratching a specimen will not tell you if it is a mineral.
  4. It tells us that calcite has cleavage.

    No. You do not test for cleavage by scratching a mineral.
